Embodiment Construction

[0074] Combine below figure 1 , Figure 8 and Figure 9 To illustrate this embodiment, objective analysis is carried out based on the patient's specific location of symptoms of ultrasound focus therapy and the location where the device can focus.

[0075] Execute Step 1: Select a specific one of the three devices, and call image 3 , Figure 5 and Figure 7 Store the focus position information of the device, determine the focusable position, and store the attitude position information of the device and the delay information of the ultrasonic array required by the focus point into a data table for FPGA call.

[0076] Step 2: Smear the treatment agent on the sick area to ensure that the ultrasonic focusing device is seamlessly combined with the human body, and place the mechanical arm of the torso treatment device appropriately to prevent dead angles due to failure to reach the designated position during the calculation process.

[0077] Step 3: Determine the position (x, y...

Abstract

The invention, which belongs to the technical field of medical ultrasonic detection and treatment, provides a wearable medical ultrasonic therapeutic apparatus and an acoustic emission array positioning and acoustic beam focusing method. Using the apparatus and method provided by the invention, problems of difficulty existing fixation equipment installation and maintenance and limited focusing region can be solved. The method comprises the following steps: step one, designing a head-mounted device, a limb-mounted device, and a trunk-mounted device, calculating equipment attitude information, and storing the information in a table manner for convenient FPGA invoking; step two, selecting one device, installing the device, and adjusting an attitude device to prevent dead angle generation; step three, operating the device, collecting magnetic positioning device information on an array, calculating a spatial attitude of the array, and carrying out positioning to determine coverage of a therapeutic region by the device; step four, determining a therapeutic focusing center, looking up the table and carrying out calculation, adjusting the attitude position and an ultrasonic array emission time delay, and forming a focusing center; and step five, with a B type ultrasonic detection, feeding back the focusing position information in real time, carrying out closed-loop feedback adjustment, and correcting a focusing position attitude error.

Description

technical field [0001] The invention relates to a wearable medical ultrasonic treatment device and an acoustic emission array positioning and acoustic beam focusing method thereof, belonging to the technical field of medical ultrasonic detection and treatment. Background technique [0002] Ultrasonic detection and treatment technology has been developed rapidly since it was applied in the medical field. Since the development of high-intensity focused ultrasound (HIFU) technology, it has received widespread attention at home and abroad. It has created a new type of non-invasive surgery in vitro. For some special The treatment and rehabilitation of diseases is a creative breakthrough. At the same time, with the improvement of medical conditions, the improvement of control technology, and the improvement of people's requirements for medical treatment and postoperative recovery, the rapid development of HIFU technology has been promoted. [0003] Existing HIFU equipment adopts a...
