Abstract
A detection array for ionizing radiation tomography for obtaining the image of at least one section of an object or organ. The array has at least one chamber (1) provided with a radiation-transparent entrance window (2) and in the chamber a detection stack (E1) incorporating a conductive polarizing plate (3) parallel to the sectional plane and a series of identical electrodes (5) parallel to the sectional plane. An insulating spacer (9) is placed between the electrodes (2) and the plate (5) and has, facing the window, at least one radiation-opaque intermediate plate (14) parallel to the sectional plane. This intermediate plate (14), the electrodes (5) and the polarizing plate (3) are disturbing elements which, separated by a distance d, make it possible to eliminate the artefacts for linear or quasi-linear inclusions in the object.
