Photosensitive device and image detector including such a device, especially two-energy image detector
First Claim
1. An image detector comprising a photosensitive device including a matrix of photosensitive points (P1 to P9), the photosensitive points (P1 to P9) being connected to line conductors (L1 to L3) and to column conductors (FA1 to FA3, FB1 to FB3), wherein each photosensitive point (P1 to P9) includes a first and a second photosensitive cell (JA, JB) each capable of storing an information item, the two photosensitive cells (JA, JB) being superposed;
- and a first and a second scintillator substance (27,
58) which are sensitive to different energies of an incident radiation and emitting visible or non-visible light in response to the incident radiation.

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.
