A typical visual inspection device can only scan one color, and a device using "Hyperspectral Imaging (HSI)" technology can distinguish all the spectra in each pixel and have the superior ability to recognize objects according to the color characteristics. HSI technology has been widely used on satellites. Because the diseased body tissues and cells also have unique spectra, scientists have been trying hard to apply HSI to the medical field. The National Institute of Standards and Technology (NIST) website reported on June 12, 2012 that the research done by scientists in this institute will make HSI equipment better applied in the medical field.
The research team leader, Nese physicist Jeeseong Hwang, said, "Every time you let a machine scan something, you need to make sure it is looking for what you want, and you have to make sure that the image analysis algorithms used are from A set of data on multiple colors extracts the correct color information. We decided to create a method for calibrating HSI devices and test their algorithms.†Its team members are interested in one that is commonly used in gene research. DNA arrays, equipment called the "Microarrayer" (the device that can arrange hundreds of tiny sample droplets in a specific area on the surface of a micromanipulator slide, so named) were performed It was modified, programmed, and then used to select chemicals of different shades to be placed on the surface of the slide. The result was somewhat like dot-matrix printing and was used to calibrate HSI equipment and image analysis algorithms. “Scientists and engineers can customize such slides, and the unique colors on the slides accurately represent the cells they hope to recognize as a special 'chemical makeup' (determined by cell color) in the HSI device, Hwang said. "This is a particularly good way to ensure that the HSI device works correctly when applied to a patient so that the surgeon can see all or a diseased tissue of a tumor."
The study is part of a large-scale research project on NIST's "Evaluation and Verification of Optical Medical Imaging Devices." The results are published in the special edition of Biomedical Optics Express.
