Abstract
Remarkably fast evolution of the diagnostic X-ray Computed Tomography (CT) in the past decade from single slice axial scanning to 64- slice helical imaging was driven by achievements in the areas of X-ray generation and detection, and data processing. We analyze in detail how the new imaging requirements translate into performance improvements of the Data Measuring System (DMS) of a CT scanner. This includes the x-ray detector, and the associated front-end electronics. Specifically, the paper enters in the requirements for the scintillator materials (crystalline, and ceramic), as well as for the photodetectors, including the new application of the back-illuminated silicon photodiodes. This paper also presents the new trends in data acquisition electronics, and high density optoelectronic packaging used in modern multislice DMS. Finally, the authors attempt to predict the future development of medical X-ray CT imaging, based on their professional experience, and imagination.
