Resolution and Interpolation


Resolution and Interpolation

Scanners vary in resolution and sharpness. Most flatbed scanners have a true hardware resolution of at least 300x300 dots per inch (dpi). The scanner's dpi is determined by the number of sensors in a single row (x-direction sampling rate) of the CCD or CIS array by the precision of the stepper motor (y-direction sampling rate).

For example, if the resolution is 300x300 dpi and the scanner is capable of scanning a letter-sized document, then the CCD has 2,550 sensors arranged in each horizontal row. A single-pass scanner would have three of these rows for a total of 7,650 sensors. The stepper motor in our example is able to move in increments equal to 1/300ths of an inch. Likewise, a scanner with a resolution of 600x300 has a CCD array with 5,100 sensors in each horizontal row. get your scanner spares from parts warehouse, its great

Most scanners have a scan area that is either letter size (8.5x11 inches, 21.6x27.9 centimeters) or legal size (11x14 inches, 27.9x35.6 centimeters).

Sharpness depends mainly on the quality of the optics used to make the lens and the brightness of the light source. A bright xenon lamp and high-quality lens will create a much clearer, and therefore sharper, image than a standard fluorescent lamp and basic lens.

Of course, many scanners proclaim resolutions of 4,800x4,800 or even 9,600x9,600. To achieve a hardware resolution with a x-direction sampling rate of 9,600 would require a CCD array of 81,600 sensors. If you look at the specifications, these high resolutions are usually labeled software-enhanced, interpolated resolution or something similar. What does that mean?

Interpolation is a process that the scanning software uses to increase the perceived resolution of an image. It does this by creating extra pixels in between the ones actually scanned by the CCD array. These extra pixels are an average of the adjacent pixels. For example, if the hardware resolution is 300x300 and the interpolated resolution is 600x300, then the software is adding a pixel between every one scanned by a CCD sensor in each row.

Another term used when talking about scanners is bit depth, also called color depth. This simply refers to the number of colors that the scanner is capable of reproducing. Each pixel requires 24 bits to create standard true color and virtually all scanners on the market support this. Many of them offer bit depths of 30 or 36 bits. They still only output in 24-bit color, but perform internal processing to select the best possible choice out of the colors available in the increased palette. There are many opinions about whether there is a noticeable difference in quality between 24-, 30- and 36-bit scanners.


Image Transfer

Scanning the document is only one part of the process. For the scanned image to be useful, it must be transferred to your computer. There are three common connections used by scanners:

    Parallel - Connecting through the parallel port is the slowest transfer method available.
    Small Computer System Interface (SCSI) - SCSI requires a special SCSI connection. Most SCSI scanners include a dedicated SCSI card to insert into your computer and connect the scanner to, but you can use a standard SCSI controller instead.
    Universal Serial Bus (USB) - USB scanners combine good speed, ease of use and affordability in a single package.
    FireWire - Usually found on higher-end scanners,FireWire connections are faster than USB and SCSI. FireWire is ideal for scanning high-resolution images.

On your computer, you need software, called a driver, that knows how to communicate with the scanner. Most scanners speak a common language, TWAIN. The TWAIN driver acts as an interpreter between any application that supports the TWAIN standard and the scanner. This means that the application does not need to know the specific details of the scanner in order to access it directly. For example, you can choose to acquire an image from the scanner from within Adobe Photoshop because Photoshop supports the TWAIN standard.

In addition to the driver, most scanners come with other software. Typically, a scanning utility and some type of image editing application are included. A lot of scanners include OCR software. OCR allows you to scan in words from a document and convert them into computer-based text. It uses an averaging process to determine what the shape of a character is and match it to the correct letter or number.

The great thing about scanner technology today is that you can get exactly what you need. You can find a decent scanner with good software for less than $200, or get a fantastic scanner with incredible software for less than $1,000. It all depends on your needs and budget.

Did You Know?

TWAIN is not an acronym. It actually comes from the phrase "Never the twain shall meet" because the driver is the go-between for the software and the scanner. Because computer people feel a need to make an acronym out of every term, TWAIN is known as Technology Without An Interesting Name!

Keeping patients safe

Amazingly no governmental regulation exists in the UK for the labelling of pathology specimens, leaving the decision of how these should be managed to the individual NHS trusts. Peter Brooks tells Laboratory News why this is one of the most important decisions they can make
The misidentification of samples in the pathology laboratory poses a risk of misdiagnosis to thousands of patients annually. Figures obtained by the Freedom of Information act reveal that between 2008 and 2009 almost 366,000 NHS specimens were mislabelled or ‘mixed-up’ in pathology laboratories. A total of 46 recorded cases during this time period were uncovered where mislabelling was found to have been related to patient death or a serious delay in treatment1.
The common occurrence of specimen misidentification can be a consequence of the insufficient protocols that many health service trusts have in place for labelling patient specimens. Errors can occur as a result of ineffective processes for identifying and tracking specimen cassettes and slides, leading to patients receiving incorrect diagnoses. This can result in patients undergoing unnecessary treatments or a failure to treat unreported conditions. To overcome this trusts and pathology laboratories must implement more advanced procedures for labelling and tracking specimens as they progress through laboratory workflows. Recently, there have been great improvements in reliable and effective technology that guarantees accuracy through automatic quality assurance and documentation to remove any potential error points during the process of specimen collection, grossing, staining, analysis and archiving.
Currently no governmental regulation exists in the UK for the labelling of pathology specimens, leaving the decision of how these should be managed to the individual NHS trusts. Many trust’s guidelines still only require specimens to be labelled manually. This prevalent practice of labelling samples by hand and lack of official policy results in a huge potential for error across the health service and the widespread incidence of specimen misidentification.
"Many technicians have no option but to write indentification information on the slide label by hand in order to match specimens with the right tissue block or patient, simply because they have no other means of doing so"
Misidentification of specimens in pathology laboratories can have significant consequences for patients through inaccurately matching slides to patient samples. In addition, a failure to treat unreported conditions can cause serious harm to patients who may also be subjected to unnecessary procedures as a result of misdiagnosis. A 2010 NHS report detailed that a pathology mix-up resulted in a patient with a benign breast condition receiving a malignant diagnosis and undergoing surgery, while another patient was wrongly given the all clear2. The cause was identified as a pathology mix-up as a consequence of specimen misidentification. The manual labelling of tissue containers and microscopic slides is still common practice today while batching of specimens and printed labels for multiple patients is also widespread. This means that although they are rare, incidences such as this can still occur.
It has been recognised by laboratory technicians for decades that the current process for identifying and tracking specimen cassettes and slides is not an accurate science. Many technicians have no option but to write identification information on the slide label by hand in order to match specimens with the right tissue block or patient, simply because they have no other means of doing so.
Highly inefficient and time-consuming, manual methods are unsurprisingly prone to potential errors, whether from illegible handwriting, incomplete sample details or the inability to track the processes that a sample has been through. Deciphering somebody else’s handwriting can be in itself problematic and prone to error. The amount of space that is designated to labelling on a slide or cassette can also be very limited meaning that vital information may be abbreviated or even omitted.
Durability of labelling is of great concern. Tissue cassettes and specimens can become unreadable after contact with chemicals or solvents or even just routine handling within a laboratory which can easily smudge text that has been handwritten. Unsatisfactory labelling is also likely to use poor quality adhesive that is not strong enough to withstand harsh chemicals, solvents or extreme temperatures. As a consequence there is a risk that labels will be removed during processing making it impossible for samples to be matched to a patient and wasting valuable time and money.
Long-term storage can also present challenges to label preservation and the ability to track specimens for long periods. Traditional methods are ineffective as handwritten labelling can be susceptible to fading over time, causing particular challenges if specimens are being stored for legal reasons or for future testing. To overcome the issues faced on a day-to-day basis it is vital that pathology laboratories implement advanced means of labelling and tracking samples to ensure the risk of label illegibility and sample misidentification is minimal.
Accurate sample labelling is the best defence for pathology laboratories against misidentification errors and their consequences. In recent years, new innovative technology has emerged that makes safety a priority and recognises the importance of satisfactory identification and traceability. Labelling specimens using automated cassette printing at the time they are required is a proven method to reduce errors while improving processes and enabling laboratories to work more efficiently. Misidentification errors can be further prevented by using barcodes to identify samples and by scanning them to record transfers and to support test entry result, enabling sample data to be tracked as it proceeds through the laboratory workflow.
To address the risks associated with sample misidentification, new labelling and tracking solutions and devices have been developed by companies (for example Thermo Fisher Scientific) to ensure that the integrity of tissue samples is preserved. By removing the risk of sample mix-up, these solutions ensure that patients receive a quick and accurate diagnosis of diseases such as cancer. This new technology enables pathology laboratories to develop “closed-loop” specimen identification and tracking systems that use advanced labelling and barcode technology to significantly reduce errors and increase the efficiency of laboratory workflows.
By implementing printing at the workstation, pathology laboratories can automatically label cassettes and ensure samples can be identified accurately by offering instantly legible type and improved information content. High-quality printing capabilities now enable cassettes to be clearly marked with a 2D barcode that provides improved clarity for laboratory staff and significantly reduces the possibility for human error. By printing barcodes and text directly onto microscope slides, the slide is resistant to chemicals, protecting barcodes and text so they always remain readable, helping to avoid sample mix-up and misdiagnosis. Furthermore, barcode sample identification and data entry saves time, enabling staff to spend more time on diagnostic procedures rather than administrative work.
An inclusive workflow removes the possibility of errors caused through the manual labelling of slides and cassettes and ensures that when a sample is taken and processed through a laboratory, it is the same sample that is collected at the other end and the correct results that are passed on to the patient. The enhanced durability offered by new technologies mean that a sample can then be archived and retrieved without any risk of deterioration to the label or fading of the text, even under extreme conditions. This not only avoids irretrievable sample loss but also offers complete confidence to the technician and the patient that the correct sample has been identified. New technologies also enable laboratories to benefit from having records that prove that samples have been through specific workflow processes without any allowance for error or mix-up.
In addition to improving efficiency at every stage of sample processing, emerging identification and traceability systems also assist laboratories in meeting Good Lab Practice (GLP) standards by providing compatibility with LIMS and other data systems.
Sample misidentification poses a significant threat to thousands of patients annually and in the most severe cases, results in individuals receiving incorrect or unnecessary treatment or failed diagnoses. Over recent years, patient safety and patient care have increasingly become the focus for healthcare trusts in the UK. Pathology laboratories play a vital role in eliminating the likelihood of identification and traceability incidences and preventing the adverse events associated with specimen misidentification.
The traditional methods of sample identification widely used in pathology laboratories are not always effective, resulting in a significant risk to patients. New technology is assisting laboratories and healthcare trusts to implement solutions that guarantee the accurate labelling of specimens, enabling laboratory staff to identify samples and significantly reduce the prevalence of misidentified, lost or unusable samples and their related consequences. This means that patients can be confident that disease processes are diagnosed correctly and as rapidly as possible.

 The Primera Signature is the world's smallest colour slide printer, which prints directly in CMYK process on special coated slides. Text, graphics and logos along with high-resolution linear and 2D bar codes on every slide significantly increases the efficiency in your lab and helps to reduce the risk of misidentification of specimens.

school furniture

There are such a large number of explanations why schools favor utilize fantastic school furniture. Some of the aforementioned explanations are in light of the fact that such school furniture fantastically improves picking up. School instruction gear is part and package of picking up and key to both educators and people. In this manner, to give a true picking up nature, the school furniture needs to be of high caliber. There are unexpected bits of furniture configured for diverse purposes. Case in point, school seats and work tables implied for general memorizing are not the same one utilized for exams. Subsequently, value furniture is of service for performing particular errands.

Value school furniture is configured for particular purposes. Case in point, lab school seats are planned in particular for the lab and classroom seats for the class. This denotes that the school seats utilized within the lab will empower understudies to fulfill lab work fittingly. This is since the seats in the lab are not the same as the aforementioned in the class. Along these lines, the school seats need to be special. These are truly fundamental not just for simplicity of studying but in addition security. When getting school training gear, the reason for which it being acquired for needs to be regarded.

A different vitality of value school furniture is that the furniture is ergonomically composed. This implies that people can sit on them for extend periods of time without encountering back wounds. Learners who utilize grave furniture come around to enduring lifelong back situations. This can meddle with their research projects right around different exercises. To stay away from so much, it is sagacious to purchase value school furniture that is planned to uphold the back of the learner. This school furniture will moreover permit the learner to feel easy when concentrating on. This interprets to phenomenal scholarly appearance that can just be attained with top notch school furniture.

Separated from lifelong back situations, there are moreover wounds that might be upheld when utilize easy value furniture. For instance, seats can break when understudies or educators are sitting on them. This will advance to wounds that might be severe. Thusly, to escape such breakages and damages, it is clever to purchase value school training supplies. This supplies is uncommonly intended for the school setting. Makers of value school training supplies, ordinarily fulfill checks to guarantee that their items are in incredible conditions. This controls a situation where a school appropriates substandard school furniture that postures a hazard to the learners.

An additional explanation why schools might as well utilize top notch school furniture is because of the price viability. Level value furniture, as specified above is certain to break. This not just aims damages but likewise creates a great deal of overheads in terms of repairs and shifts. Accordingly, school furniture ought to be of high caliber to recovery on some of the aforementioned expenditures. When top notch furniture is acquired, there should not be any require to be reinstated for a considerable length of time. This not just recoveries prices but additionally guarantees that memorizing is not hindered for any explanation. Consequently before acquiring school furniture, it is canny to recognize the value of every last trace of the pieces.

Identifying the need Located on Manhattan’s Lower East Side in New York City, the Bowery Mission has served the area’s homeless population for 130 years. Today, the Bowery Mission serves 18,000 meals every month through a variety of inhouse programs, including a residency program, an overnight shelter, a food bank and park outreach. Until recently, the shelter had very little in the way of a secure ID card program. Staff members received cut-and-paste IDs, and creating them was both time-consuming and laborintensive. No IDs were available for the shelter’s residents or guests. When the shelter’s chaplain saw a guest’s full-color photo ID card from another local soup kitchen, however, he realized better technology was available. “When I saw that badge, I got curious about what we could do with a real ID system,” said Pastor Reggie Stutzman, director of compassionate care for the Bowery Mission. Stutzman contacted Datacard Group, who connected with local dealer Metropolitan Data Solutions to put together an appropriate solution for the Bowery Mission. Datacard donated the system and supplies, and Metropolitan Data Solutions donated the time required to deliver, set up and install the solution, as well as train staff members how to use it and set up an initial batch of card designs. Assembling a solution The solution for the Bowery Mission includes a Datacard® SD360™ Plus card printer with full-color, two-sided printing capabilities, as well as Datacard® IDCentre™ Silver identification software, a Datacard® Photo Pointe™ solution for image capture and an initial batch of color ribbons and card stock. According to Stutzman, the Bowery Mission will use the solution to create photo IDs for staff members and two other key groups: men in the shelter’s nine-month residential program and its overnight guests. “It is important to give our homeless guests a free, legitimate photo ID they can use outside our facility,” Stutzman said. “Acquiring any kind of full-color ID card can be difficult, so many of our guests do not have one. Now we can give them one and make their lives that much easier.” Strengthening security Improving security is a secondary advantage of having the Datacard solution in-house. Currently, the Bowery Mission is building a photo database of its guests, which include a very high volume of people. “We see so many people every day,” Stutzman said. “The photo ID database will be very helpful. It will allow us to create a photo roster of guests, and help us differentiate residents from nonresidents. It will also help us identify people who have violated our policies and have been asked not to return for 30 days. Also, if the police need our help locating someone, having a current photo to work from is much easier.” About Datacard Group Datacard Group is building on a 40-year heritage of innovation and customer success.
