Description

In the framework of a 2022 PRIN Project a new system for computed tomography based on a Timepix4 sensor coupled with CdTe semiconductor has been developed in collaboration between the Department of Physics of the University of Ferrara and the Department of Physics and Astronomy of the Univesity of Bologna.
A small area sensor with 512x448 pixels of 55 micron size each onstitutes an array of photosensitive detector with spectrometric capability. Acquisitions with conventional low power laboratory microfocus X-ray tubes may undergo to photon energy thresholding or binning for selective CT reconstructions and specific materials characterization in the object under analisys. Promising achievements require fine calibration work, detector imaging performace characterization, data processing workflow development in order to be reached. The present work shows how the system has been designed and built and the first tests with X-rays made in Bologna.
