HIFU probe adjustment frame and adjustment method based on ultrasonic imaging

Abstract

The invention belongs to the ultrasonic technology field and discloses an HIFU probe adjustment frame and an adjustment method based on ultrasonic imaging. The adjustment frame comprises a crossbeam arm, a first fixing device, a second fixing device and a controller. The first fixing device is connected to the crossbeam arm through a first swing arm and is used for fixing a high frequency imagingprobe. The second fixing device is connected to the crossbeam arm through a second swing arm and is used for fixing a low frequency HIFU probe. The controller is connected to the first swing arm and the second swing arm and is used for adjusting the position of the second swing arm and / or the low frequency HIFU probe according to the position parameter of the high frequency imaging probe. The position parameter comprises an angle between the first swing arm and the crossbeam arm, and / or an angle between the high frequency imaging probe and the first swing arm, and / or a target area position detected by the high frequency imaging probe. In the invention, a high frequency is considered and simultaneously a low frequency spectrum segment is covered, and the high frequency imaging and low frequency HIFU probes are used to realize simultaneous imaging and dynamic focusing.

Description

technical field [0001] The invention relates to the field of ultrasonic technology, in particular to an ultrasonic imaging-based HIFU probe adjustment frame and an adjustment method. Background technique [0002] High Intensity Focused Ultrasound (HIFU) is a technology that focuses ultrasonic waves onto diseased tissues (treatment targets) in vivo, and achieves the purpose of treating diseases through the mechanical, thermal, and cavitation effects of ultrasound. With the characteristics of non-invasive, non-radiation, deep treatment depth and low cost, it has been more and more popularized and recognized clinically. [0003] At present, there are two main ways of HIFU focusing: geometric focusing and phased array focusing. [0004] Geometric focus: eg figure 1 and figure 2 As shown, the focusing of the sound beam can be achieved by molding the piezoelectric layer of the probe into a concave shape or making a Fresnel ring distribution, or adding an acoustic lens in front...
