ABSTRACT:
The invention relates to a photosensitive matrix (2) permitting the simultaneous acquisition of two images, especially radiological images, and which offers at the same time a maximum sensitivity and a maximum image resolution. The matrix (2) of the invention includes photosensitive points (P1 to P9) disposed in lines and in columns. According to a feature of the invention, each photosensitive point (P1 to 9) includes two photosensitive cells (JA, JB), the first ends (3A, 3B) of which are connected to a same line conductor (L1 to L3), and the second ends (4A, 4B) of which are connected to different column conductors.
