Problems solved by technology

However, since this method needs to insert a temperature sensor into the human body, which will not only cause pain to the patient, but also cause wound infection, it is difficult to apply the direct physical measurement method to the actual treatment of the thermotherapy machine
[0008] Non-destructive temperature measurement is a method of directly obtaining the temperature inside the human body without causing physical damage to the human body. There are many principles of non-destructive temperature measurement, such as CT, ultrasound, etc., but they are currently in the theoretical research stage.
[0009] In fact, doctors usually confirm the parameters used in treatment according to their own actual treatment experience, so the selection of treatment parameters is very random, and it cannot be guaranteed that each treatment parameter can achieve the best treatment effect

Abstract

The present invention relates to an ultrasonic heat therapeutic equipment and its focal temperature prediction method. Said ultrasonic heat therapeutic equipment includes: high-energy focusing ultrasonic source, B ultrasonic probe mounted in the interior of ultrasonic source, computer and control table, in which the described computer includes input unit for inputting therapeutic parameters, focal temperature inquiry unit which is connected with input unit and is used for inquiring corrected temperature reference listing according to inputted parameters to obtain focal temperature and output unit for outputting described focal temperature. It can implement non-destructive temperature measurement of focus, can protect human body against damage and can ensure optimum therapeutic effect.

Description

technical field [0001] The invention relates to a medical device for killing lesion tissue by using the ultrasonic (HIFU) wave source outside the patient's body to emit high-energy focused ultrasonic waves at the focal point to kill diseased tissues, in particular to an ultrasonic hyperthermia machine and a method for predicting the focal point temperature. Background technique [0002] At present, HIFU treatment device is one of the hot spots of medical research at home and abroad, and its clinical application has achieved good results. A practical in vitro HIFU hyperthermia machine generally consists of the following parts: [0003] A. High-energy focused ultrasonic source and drive circuit - used to generate high-energy focused ultrasonic. [0004] B. Positioning system - used to find the treatment target and move it to the focus of the ultrasound transducer. It includes a medical imaging system (mostly a B-ultrasound machine), a patient-carrying device (such as a bed s...
