Contro system for the improvement of CMOS-Technology for X-RAY contrast phase imaging

Abstract

The present dissertation is intended describing the results of the research project developed at the μTomo Laboratory of the STAR light source, as part of the PON MaTeRiA Project at the University of Calabria. The project involved making the data acquisition and treatment tools by developing a complete software package in LabView language for remote control of the μTomo microtomography system. The programming consisted of control of the whole experimental station including five stepper motors and a flat panel detector necessary for the sample alignment and image acquisition. The first tomographic investigation performed by the μTomo beamline are reported and discussed. Furthermore, the software was evolved to be integrated into the STAR control system i.e. to run as an EPICS server in LabView language and permit the remote control on a EPICS platform at the same control level as the STAR source As part of the research project, in the framework of a scientific collaboration with the ID17 beamline dedicated to biomedical imaging, radiation biology and radiation therapy, of the ESRF Synchrotron in Grenoble (F), a Graphic User Interface was developed for the implementation of the Propagation-based phase-contrast imaging technique, the software was tested by carrying out two micro-CT experiments. For the sake of a clear description this dissertation was divided into four parts: Chapter I: Theoretical foundation, description of fundamentals on X-ray microtomography. Chapter II: Hardware Implementation, detailed description of acquisition system. Chapter III: Development and testing of Data Acquisition Software Chapter IV: Results and Discussion on benchmark experiments carried out to verify the micro-tomography systems performance
