Abstract
In scintigraphic cameras according to the invention, the treatment of the signals generated by each point of the image in the observation elements is carried out in two steps: a first device with a relatively short delay (0.55.mu.s) roughly localises the point and, at the same time, eliminates the signals outside a given energy band and corrects any inequalities of gain from one point to another of the image; a second device with a longer delay (3.mu.s), which receives the same signals, with a delay equal to that of the first device, and the results of the treatment effected in the latter, defines the precise position of each point.
