X-ray sources of nanosecond pulses based on semiconductor opening switch for CT

Abstract

This study describes the development of prototype CT scanners with 2 different pulsed X-ray sources. X-ray sources used in this work have a semiconductor opening switch. It is used to generate high voltage pulses and provides pulse repetition frequency up to 5 kHz. The work uses two pulsed X-ray sources, which have different peak voltages and pulse energies. Tomographic sections and 3D images for test objects are obtained, the advantages of pulsed X-ray sources compared to continuous sources are discussed.
