Large flat plate current gathering resistance measurement device and method applied to breast cancer

Abstract

The invention provides a large flat plate current gathering resistance measurement device and method applied to breast cancer. The large flat plate current gathering resistance measurement device comprises an upper current gathering electrode array and a lower current gathering electrode array, which are in parallel arranged up and down and have the same upper and lower surfaces, wherein electrode regions of the upper current gathering electrode array and the lower current gathering electrode array are semi-circles with the diameter of 160mm; electrodes are arranged according to a honeycomb; the outer diameter of the electrodes is 4.5mm and the distance between the electrodes is 1mm; 392 electrodes are distributed in each electrode region; the upper current gathering electrode array and the lower current gathering electrode array can rotate for 360 degrees and breasts can be measured at any angle; when the upper current gathering electrode array and the lower current gathering electrode array are used for measuring, a partition measurement manner is adopted; each 7 electrodes in the 392 electrodes form a region group; each electrode occupies a small region; the 7 electrodes form one region group; the electrodes are triggered from a certain small region, span across two small regions along the vertical direction of an edge, turn leftward or rightward for 60 degrees and then span across one small region so as to reach the same group of electrodes; the electrodes of the same small group are measured simultaneously for each time until all the electrodes are detected. According to the large flat plate current gathering resistance measurement device and the method provided by the invention, the sensitivity of disturbance regions in breast tissues of the electrodes can be improved.

Description

technical field [0001] The invention belongs to the electrical impedance scanning imaging in the technical field of medical imaging, and in particular relates to a large-plate converging impedance measuring device and method applied to breast cancer. Background technique [0002] Since the electrical admittance (impedance) of human breast cancer focus tissue is greater (smaller) than that of normal breast tissue, breast cancer detection or diagnosis techniques based on measuring tissue electrical impedance or admittance have been developed rapidly. Since the concept of impedance is more familiar, such techniques are referred to as electrical impedance techniques. At present, this field has entered the stage of non-invasive in vivo measurement from isolated tissue measurement and invasive in vivo measurement. Electrical impedance scanning imaging technology (electrical impedance scanning, EIS) is a typical representative of electrical impedance technology in the field of bre...
