[Interpretation of autoradiogramms and images of biological objects with the electronically operating image analyzer. "Densitron II". 1. The mode of work, efficiency, and possibilities of application of the apparatus (author's transl)].

Mode of operation and general parameters of efficiency of the Densitron II, an automated, electronically operating image analyzer, are demonstrated in autoradiographs and histological preparations, as an example. In this apparatus, a condensation and preparation of data is effected by isolated representation on a TV colour monitor of all the image - points whose transparency is the same or lies within a determined, freely selected interval. Simultaneous estimation of both transparency and area is possible.
