specific Embodiment approach 3

[0076] Specific embodiment three: similar to specific embodiment two, for handheld therapy, the operator can wear special gloves with markers on the gloves to show the outline of his hand, and use multiple cameras to capture real-time images of the hand-held ultrasonic transducer and replay them immediately. Construct a three-dimensional space image, extract the contour of the ultrasonic transducer and the hand from the image according to the contrast of optical absorption, record the real-time position of the ultrasonic transducer according to the position changes of the glove and the contour of the ultrasonic transducer in the continuous images taken, and judge the Displacement of an ultrasound transducer over time. It is also possible to directly extract the contours of hands and ultrasonic transducers using image recognition technology.

specific Embodiment approach 4

[0077] Embodiment 4: The ultrasonic transducer is installed on a mechanical moving device (such as a 3-dimensional linear guide frame, a mechanical arm with 3-6 degrees of freedom, a hydraulic motion mechanism, etc.), and the ultrasonic transducer is calculated according to the position recording function of the mechanical motion mechanism. Transducer displacement over time.

[0078] Specific implementation plan five: Built-in or install miniature single or multiple motion gyroscopes in the ultrasonic transducer, the gyroscope generates position information with the movement of the ultrasonic transducer, and calculates the position of the ultrasonic transducer over time according to the position information of the gyroscope. displacement.

[0079] (2) Real-time monitoring of the acceleration or movement speed of the ultrasonic transducer

specific Embodiment approach 1

[0080] Embodiment 1: An acceleration sensor or a speed sensor can be used to monitor the acceleration or speed change of the ultrasonic transducer.

Abstract

The invention provides a position-monitoring method and a position-monitoring system for an ultrasonic transducer, which belong to the field of medical ultrasonic therapy. The position-monitoring method for the ultrasonic transducer includes the following steps: acquiring the treatment position change of the ultrasonic transducer; and adjusting the operating parameters of the ultrasonic transducer according to the acquired treatment position change, so that preset ultrasonic irradiation energy can be obtained at the treatment position. The technical scheme of the invention can enhance the safety of the ultrasonic transducer in use and increase the quality of ultrasonic therapy.

Description

technical field [0001] The invention relates to the field of medical ultrasonic therapy, in particular to a method and device for monitoring the position of an ultrasonic transducer. Background technique [0002] It is well known that the interaction of ultrasound with human tissue can produce several biological tissue effects. These biological tissue effects can be divided into thermal effects and non-thermomechanical effects according to the local sound intensity of ultrasonic waves and the sound wave emission mode. Tissue thermal effect refers to the absorption of ultrasonic energy by cells causing them to heat up to thermal necrosis. Tissue non-thermomechanical effects refer to phenomena such as cell morphology changes, rupture, and apoptosis due to the increase in cell activity caused by acoustic cavitation, acoustic flow, and local small-amplitude vibrations. The physical factors that affect the effect of ultrasound on biological tissues include the focused form of t...
