Abstract:
1. A radiological imaging device, comprising: an X-ray source configured to transmit a luminous flux to a subject, means for controlling the source, an X-ray detector configured to detect a plurality of signals derived from an interaction of the luminous flux with the subject, means for digitally processing the plurality of signals, and means for viewing the plurality of signals, characterised in that: the X-ray source is a pulse source configured to generate pulses that have a pulse duration that is less than 1 ms and is greater than 0.1 ms, the means for controlling is configured to define the pulse duration of the pulses and an intensity of the pulses, and the X-ray detector has a response time that is less than 0.1 ms, the X-ray detector being a junction p/i/n comprising a zone p, a zone i, and a zone n, wherein the zone i is a relatively thick epitaxial layer made of an unintentionally doped semi-conductive material comprising GaAs and having a high atomic number to directly convert photons into electrons.
