Problems solved by technology

Different manufacturers of magnetic resonance and database servers have different interfaces, and even run on different operating systems. It is impossible to develop different communication protocols and interfaces for different manufacturers, because this will bring more development and maintenance costs.
These limitations bring great difficulties to software design

Embodiment Construction

[0041] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0042] figure 1 The HIFU system based on MR guidance of the present embodiment mainly consists of three parts: MR device ( figure 1 Middle MRI), HIFU device (in this embodiment, P-HIFU device, namely figure 1 Medium P-HIFU) and control terminal (i.e. figure 1 Middle Console). Magnetic resonance (MR device) is mainly used to collect image information of lesions, which can be used for preoperative treatment planning, intraoperative treatment control (including real-time temperature measurement, etc.) and postoperative treatment effect evaluation. The P-HIFU device is mainly used to generate high-intensity focused ultrasound and control the positioning of the ultrasound probe. The control terminal controls the HIFU device 2 to perform surgical treatment of the patient according to the image information.

Abstract

The invention discloses an HIFU system based on MR guidance and a control method. The HIFU system comprises an MR device, an HIFU device and a control terminal. Information interaction is carried out between the MR device and the control terminal as well as between the control terminal and the HIFU device through message-oriented middleware. The control method comprises the following steps that at first, a current treatment position of the HIFU device is obtained, phase position data are obtained through calculation according to the current treatment position, and the HIFU device is started to carry out treatment; image information is displayed after being collected by the MR device, temperature distribution and heat metering distribution of the current treatment position are calculated according to the image information and displayed, and treatment is stopped after the preset effect is achieved. By means of the message-oriented middleware, interaction among the MR device, the HIFU device and the control terminal becomes easy, MR devices, HIFU devices and control terminals of different manufacturers are compatible, the development cost is reduced, and the openness and the flexibility of the system design are improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an MR-guided HIFU system and a control method. Background technique [0002] High-intensity focused ultrasound (HIFU) refers to the generation of ultrasound through a piezoelectric transducer with an alternating voltage. Through a certain focusing method, the ultrasound can be focused into a small focal spot. The sound intensity at the focal spot is the diagnostic ultrasound. (0.1W / cm 2 ) 4-5 times the order of magnitude, can reach 1000-10000W / cm 2 . High-intensity focused ultrasound utilizes the biological and mechanical effects of ultrasound in the human body, and can cause acute coagulation necrosis of tissues outside the body in a short period of time, so as to achieve the purpose of minimally invasive or even non-invasive treatment. [0003] High-intensity focused ultrasound was first used for craniotomy to treat Parkinson's disease; with the development of techno...
