We used to use a traditional microscope for our research. When using a traditional microscope, we don’t have a large overview of the specimen, and the scope of the field is very small. Therefore, the tissues and specimens that we need to view are too big for our little microscope. It took too much time to evaluate the scores and conduct statistics. We sometimes have 600-800 slides to look through so that we can count specific cells and immunostained cells on each slide. The countless hours it takes to look through all the slides though a traditional microscope was unbearable. With our previous microscope, we would have to take 20 separate images to view the entire specimen. Then comes the problem with manually stitching the images together into one large image.
