System for ablation zone detection

Abstract

A system for detection of an ablation zone, comprising: an ablation device configured to mechanically agitate at least a portion of at least a portion of tissue proximate to at least a portion of the ablation device by intermittently pumping fluid through at least a portion of the ablation device; Configured to: receive a plurality of return signals based on the delivered ultrasound energy from a plurality of respective portions of the tissue; and the computing device receives a plurality of return signals from the ultrasound device, detects in the plurality of return signals based on the microwave energy delivered to the tissue a plurality of corresponding Doppler frequency shifts, detecting the response of the tissue to mechanical agitation in the plurality of return signals, determining the characteristics of the ablation zone based on the plurality of Doppler frequency shifts; and causing the display device to represent at least a portion of the tissue by displaying Representation of image and ablation zone characteristics, the computing device is further configured to display on the display device an indication of the size and shape of the ablation zone on the ultrasound image based on the plurality of Doppler shifts and the response of the tissue to the mechanical agitation.

Description

technical field [0001] The present disclosure relates to the use of ultrasound for ablation prediction and monitoring, and more particularly, to the use of Doppler effect detected by ultrasound and elastography to predict and monitor ablation zone shape, size and progression. Background technique [0002] Ultrasound scans of the patient's body are often used to confirm the placement of surgical tools at the treatment site within the patient's body. However, once treatment has begun, there is no way to predict or confirm the area, extent and / or progression of treatment other than through the use of software models. The present disclosure provides improvements to the use of ultrasound scanning during treatment to predict and confirm the size, shape and location of the treatment area and the progress of the treatment process. Contents of the invention [0003] A method of ablation zone detection is provided according to the present disclosure. In one aspect of the present d...
