Multimedia detectors for medical imaging

A method for obtaining an image of a subject exposed to incident radiation comprising the steps of:

• exposing a detector to incident radiation projected through a sample,
• wherein the detector comprises a gas microstrip detector, including
• a substrate having on a first surface a plurality of alternating anodes and cathodes,
• a detector cathode spaced apart from and opposing the substrate first surface,
• a plurality of electrodes disposed on an opposite surface of said substrate and oriented substantially perpendicularly with respect to said plurality of alternating anodes and cathodes, said plurality of electrodes separated into a front zone and a back zone, and
• a zone for disposing a gaseous medium between the substrate and the detector cathode and for receiving incident radiation from the sample, wherein the incident radiation produces photons by ionization of the gaseous medium;
• absorbing the photons in said detector, by applying an electric field between the detector cathode and said plurality of electrodes to produce a first image signal detected by said front zone and a second image signal detected by said back zone;
• and
• producing an imaging signal from said first and second image signals.
