In the recent years, researchers have made a huge step forward in the biomedical imaging arena through development of solid-state image receptors like photo sensitive flat-panel arrays, micro machinized piezo-lectric arrays and quantum dots. Images get stored into a computer by dividing the images into small segments called picture elements, or pixels. Each image pixel is then assigned a single numerical value.

That value denotes the color of the image assuming the image is indeed a colored one. If it's simply a black and white image, then a shade of gray, known in the field as gray level, is stored.

This is an educational documentary about the imaging in the biomedical field. We explain from a tech point of view.
