Abstract： |
The present invention belongs to the field of basic biological tissue mechanical attribute measuring technology. The supersonic elastic imaging balance pressure measuring unit includes one extruded plate, one B-mode supersonic probe, N pressure sensors, one multi-channel data acquiring card and one computer. The B-mode supersonic probe and the N pressure sensors are installed on the extruded plate, the B-mode supersonic probe is located in the middle part of the plate and the N pressure sensors are distributed around the probe. The outputs of the N pressure sensors are connected to the multi-channel data acquiring card separately, and the multi-channel data acquiring card is inserted in the mainboard of the computer. The present invention utilizes several pressure sensors for regulating the tissue compressing direction and compressing amount to ensure the precision of supersonic elastic imaging. |
