Abstract

The invention relates to a high-precision multi-frequency distributed medical impedance imaging measuring system and method.The system comprises a main control panel and at least three front end measurement collection panels.The main control panel is connected with an upper computer and the front end measurement collection panels.The front end measurement collection panels are connected with an electrode.The main control panel comprises a first communication module, a drive signal generation module, a second communication module, a first handshaking signal module, a synchronizing signal generation module and a main control chip.The main control chip is provided with the drive signal generation module, controls the synchronizing signal generation module to generate a clock synchronizing signal, and conducts communication with the front end measurement collection panels through the second communication module and the first handshaking signal module.Each front end measurement collection panel comprises an excitation switch selection module, a data collection module, a third communication module, a second handshaking signal module, a measurement controller and an interface module.Compared with the prior art, the high-precision multi-frequency distributed medical impedance imaging measuring system and method have the advantages that quick and accurate collection and safe isolation of impedance information under multiple frequencies are realized.

Description

technical field [0001] The invention relates to the technical field of electrical impedance measurement, in particular to a high-precision multi-frequency distributed medical electrical impedance imaging measurement system and method. Background technique [0002] Electrical impedance imaging technology is a non-invasive measurement technology for measuring the internal conductivity distribution of the measured object. It injects current excitation signals and collects voltage response signals through electrode pairs attached to the surface of the measured object, and can reconstruct the measured object by solving the electromagnetic field inverse problem. The conductivity distribution inside the measured object is displayed in images, providing users with intuitive detection information and reliable results. The distribution of conductivity is related to the physiological state and health status of the measured object and has high sensitivity. This technology has the advant...
