Hardware and Software
A bench/fixed microscope or hand-held portable microscope can examine specimens like tissue samples, blood and objects with 2-7000x zoom magnification and a pixel resolution up to 2560 x 1920 pixels. Some models incorporate a swiveling camera head for angled viewing.
The microscope or high-resolution digital camera with magnifying properties connects via USB cord to a computer equipped with video acquisition software. Some microscopes come with a built-in hard drive and optical and flash drives. Other models have a memory stick port for recording without a computer.
Video microscopy enables medical professionals to increase capabilities even more through image processing. Samples can be sectioned, resolution improved, depth discrimination manipulated, light can be scattered and diffused, and the background eliminated. Taking a digital picture or video also safeguards the quality and longevity of the image.
Automated image analysis makes it easier to extract and analyze data without the factor of human error. For example, cells can be examined with statistical models that differentiate cancer cells from normal cells. Either a human can look at the cells first, and use automated analysis afterwards or use the automated model first, and a human interpretation afterwards.
