Content:
Technical Fundamentals of Radiology and CT is intended to cover all issues related to radiology and computed tomography, from the technological point of view, both for understanding the operation of all devices involved and for their maintenance. It is intended for students and a wide range of professionals working in various fields of radiology, those who take images and know little about the workings of the devices, and professionals who install, maintain and solve technological problems of all radiological systems used in health institutions.
