Abstract

The invention applies to the field of clinical medicine and provides a focusing target adjusting system, method and device for magnetic resonance-guided focused ultrasound. The system comprises: a magnetic resonance scanning chamber, a scanning bed positioned in the magnetic resonance scanning chamber, a longitude probe moving guide fixedly connected to the front end of the scanning bed, a latitude probe moving guide perpendicularly and slidably connected to the longitude probe moving guide, an ultrasonic array probe slidably connected with the latitude probe moving guide, a magnetic resonancescanner slidably connected with the scanning bed, a human-machine interaction terminal positioned outside the magnetic resonance scanning chamber, a master industrial personal computer connected withthe human-machine interaction terminal, and a signal controller connected with the ultrasonic array probe, the magnetic resonance scanner and the master industrial personal computer. A fixed coordinate conversion relationship is established between the ultrasonic array probe and magnetic resonance images through the system, so that a focused target can be precisely adjusted through position shiftand phase adjustment of array elements of the ultrasonic array probe, and deep brain nerves are controlled.

Description

technical field [0001] The invention belongs to the field of clinical medicine, and in particular relates to a focus target adjustment system, method and device for magnetic resonance-guided focused ultrasound. Background technique [0002] Focused ultrasound can be used for tissue thermal resection, and magnetic resonance image-guided focused ultrasound therapy can better target location, preoperative planning, and intraoperative temperature monitoring. In the focused ultrasound treatment plan, the focus positioning method usually uses magnetic resonance acoustic radiation force imaging. Displacement, and will not cause tissue displacement at the non-focus) for phase encoding, so that the focus position can be determined, and the tissue displacement can be quantified. However, since there is no control system product for the fusion of magnetic resonance and ultrasound, the current magnetic resonance system and The ultrasound system uses an independent coordinate system, an...
