Developing principles and functioning algorithms of the hardware-software complex for electrical impedance tomography of biological objects

This paper discusses the general principles of developing, and algorithms ofoperation of the hardware and software complex for electrical impedance tomography of biological objects, and proposes technical solutions for building the device as a whole, and in separate blocks. It is proposed to use the modular-assembly principle as the basis of the hardware-software complex. The advantages of the proposed approach and the possibilities of its implementation in the ready device are described. The requirements to the electrode belt are defined, and structural diagrams are developed for the measurement board, generator board and the microprocessor unit. The principles of interaction between main units are developed. The archiving unit and record-keeping procedures, display unit, control unit, the unit of communication with a PC are described. Attention is paid to development of the patient's records. The main algorithms for device operation are defined, and the operation diagram is proposed. The logics of the whole hardwaresoftware complex operation is explained. It is proposed to develop independent program products for measuring reconstruction and data visualization from a biological object. To ensure portability and mobility, a battery pack is provided in the cabinet. It is emphasized that special attention should be paid to the relation between the hardware and software complex and the modern methods and communication protocols for processing tomographic images, such as DICOM.
