Development of a power supply for multi-angle electric impedance tomography complex

Abstract

In the present work, the development of a multi-channel power supply for the hardware part of the hardware-software complex of multiangle electric impedance tomography is considered. The requirements for the developed module are considered based on the selected hardware components, as well as the patient and medical personnel safety requirements, taking into account the standards developed by the International Electrotechnical Commission. Taking into account the formulated requirements, a structural, electrical schematic diagram of the power supply was developed, as well as a printed circuit board and an assembly drawing, and a prototype model was built. The issues of patient and medical personnel safety during the research using the multi-angle electric impedance tomography method with the use of the developed module are considered, including in the case of joint use with electrosurgical devices or defibrillators.
