How to evaluate the quality in a system of video-microscopy in the field of anatomic pathology

The acquisition of a video microscope image is explained by the concept of modulation transfer function to describe the quality of a microscope which should target a sensor of a video camera to allow around 50 pairs of lines per mm with a good contrast in the video-monitor. Taking this into consideration, high aperture lenses, a microscope with infinity optics, a low power video adapter and a high quality camera must be used.
