Title:
COMPATIBILITY SYSTEM AND METHOD FOR SYNCHRONOUS WORKING BETWEEN MAGNETIC RESONANCE IMAGING AND FOCUSED ULTRASOUND THERMAL ABLATION
Document Type and Number:
WIPO Patent Application WO/2023/083165
Kind Code:
A1
Abstract:
A compatibility system and method for synchronous working between magnetic resonance imaging and focused ultrasound thermal ablation. The synchronous working compatibility system comprises a magnetic resonance device and a focused ultrasound device, and further comprises a signal collector (201) and a control circuit (202) connected to each other; during an imaging process of the magnetic resonance device, the signal collector (201) detects an RF signal (102) of the magnetic resonance device, and the control circuit (202) records a trigger moment of the RF signal, generates, on the basis of the trigger moment of the RF signal (102), an enable signal that triggers the focused ultrasound device to start heating, and controls the heating duration of the focused ultrasonic device according to an echo time TE. Compared with the prior art, the synchronous working compatibility system has the advantages of good compatibility, high safety and the like.
