title: The use of microcomputers for the quantitation of light intensity patterns using digitized video signals.
abstract: We have developed an inexpensive yet versatile microcomputer-based system for quantitating light intensity levels in autoradiographs. This system employs a standard video camera interfaced to an analog-to-digital convertor. A program has been written for this system which can measure intensities within a defined region of an autoradiograph, permitting an easy and accurate quantitation of spots or bands of irregular shape.
