<p>A radiation image detecting system with the image divided into pixels (Sij). In this system the pixel signals are detected with a method of coded aperture. The pixel signals corresponding to the pixels contained in square sub-matrix are obtained in the form of coded signals by being detected a plurality number of times successively with a plurality of sensor groups (a-b-e-f, b-c-d-e) which are made purposefully different from one another in the number, arrangement pattern and size of the sensors (A0, A1, B0, B1). Each sensor in every sensor group, in general, covers a plurality of pixels (A00, A01, A10, A11), but the sensors in some sensor groups does not completely cover all the pixels included in the sub-matrix with some pixels left in a state that no signal is detected therefrom. The output signals from sensors are arithmetically treated with a computing means (5) so as to finally give a radiation image consisting of of pixels supposed originally on the image receiving plane (3).</p> |
