Abstract

The invention relates to a focused ultrasound device with two-dimensional imaging and HIFU treatment for small animals, comprising a platform, wherein the platform is connected with a pillar, the pillar is installed with a moving mechanism, and the moving mechanism is connected with a focusing transducer; The motion mechanism and the focusing transducer are electrically connected to the control host. As that small animal has the characteristic of small volume and shallow treatment depth, the invention adopts the design of a focused ultrasonic transducer with high working frequency, short focallength and fixed focus to realize miniaturization of the focused transducer and miniaturization of a focused ultrasonic device integrating two-dimensional imaging and treatment. The movement mechanism of the invention realizes the movement of the coronal plane of the small animal; focusing transducers enable imaging and treatment of the focal zone; a control panel enables 2D imaging and planned treatment; the invention realizes the visualization of coronal HIFU treatment in small animals, in order to reduce the manipulation time and improve the safety and effectiveness of HIFU treatment in small animals.

Description

technical field [0001] The invention relates to the research field of living tumor imaging and treatment, in particular to a focused ultrasound device for small animals with integrated two-dimensional imaging and HIFU treatment. Background technique [0002] HIFU refers to High Intensity Focused Ultrasound, and its treatment source is ultrasound. This technology focuses low-energy ultrasound outside the body on the target area in the body, and produces biological effects such as transient high temperature, cavitation, and mechanical action in the tumor, killing tumor cells in the target area. [0003] Currently, HIFU products treat humans. Usually, the tumor in the human body is a certain depth from the epidermis, about 10-160mm, and the tumor size is relatively large. Considering the propagation characteristics of human body ultrasound, HIFU products choose a lower frequency of ultrasound to produce a larger focal area; at the same time, the area of ​​the ultrasonic sound-...
