Quantum Imaging X—ray CT Systems Based on GaAs Radiation Detectors Using Perspective Imaging Reconstruction Techniques

The work presents two generations of developed portable quantum X—CT mini-systems which utilize monolithic semi-insulating GaAs detectors. This contribution describes the present status of the assembling of the new portable X—ray CT mini system. Developed modification of the X—ray image reconstruction based on perspective imaging techniques has been experimentally verified on testing phantoms and practically implemented for processing images of real test objects. Performed measurement of the performance of the SI GaAs detectors and the integral spectra of ASIC DX64 readout chips are also mentioned.
