Abstract

The invention discloses a modular high-speed electrical impedance imaging device and a method for using the same. The device comprises N independent electrode modules, an MCU connected to the independent electrode modules, positive excitation and negative excitation connected to the MCU, and N independent electrode modules. Including independent electrode module 1, independent electrode module 2 to independent electrode module N, independent electrode module includes input port and output port, each independent electrode module is connected with output port through input port, MCU is connected with input port of independent electrode module , each independent electrode module is connected to an electrode. The present invention implements systems with different numbers of electrodes according to a unified design scheme by means of a system bus. This modular design method allows the system to be used in the usual 8, 16, and 32 systems without changing the system structure, and can even be directly used in more electrode systems to achieve three-dimensional multi-slice applications.

Description

technical field [0001] The invention belongs to the field of electrical impedance imaging, in particular to a modularized high-speed electrical impedance imaging device and a method of using the same. Background technique [0002] The electrical impedance imaging device is a multi-electrode control system, and the low-speed electrical impedance imaging device basically consists of 4 multiplex switches. High-speed electrical impedance imaging devices require simultaneous acquisition, so each electrode requires electrode amplification and digital-to-analog conversion detection processing, which makes the system much more complicated than low-speed devices. This brings about the problem that different numbers of electrodes used for different purposes require different system designs. [0003] Chinese patent CN2010800394959 Electrical Impedance Imaging discloses an apparatus for electrical impedance imaging comprising electrodes arranged on an electrode carrier in an arrangemen...
