Abstract
In a device comprising one or a number of X-ray beams of suitable shape and at least one cell for detecting X-rays which have passed through the organ to be analyzed, the detection cells are ionization chambers comprising two parallel electrodes separated by a radiation-detecting medium for converting the X-rays to electron-ion pairs. The electrodes are connected to two terminals of a voltage source and the detection cells are associated with means for measuring the charge collected during a predetermined period of time under the influence of the X-rays.
