Ultrasonic therapy tissue temperature change display equipment using digital grey scale processing

Abstract

In ultrasonic therapy, the change of the grey scale of a B-mode ultrasound image of a treated point and the change of tissue temperature have a known relationship, so temperature change conditions corresponding to the treated point can be obtained by observing the change of the grey scale of the B-mode ultrasound image of the treated point so as to get an idea of treatment effect. The ultrasonic therapy tissue temperature change display equipment using digital grey scale processing of the invention comprises a B-mode ultrasound image acquisition module, a treated point grey scale determination module and a grey scale curvilinear graph display module which are sequentially connected. In the ultrasonic therapy, the digital grey scale processing of the B-mode image of the treated point is performed, the tissue temperature change conditions are monitored accurately in real time and a curve of the change in tissue temperature of the same treated point before and after treatment is directly displayed in a graphical mode, the anesthesia time of a patient in a treatment process is reduced, and the treatment efficiency is improved and the treatment is finished more safely and effectively.

Description

technical field [0001] The invention relates to the field of ultrasonic therapy auxiliary observation equipment, in particular to a device for displaying tissue temperature changes in ultrasonic therapy using digital grayscale processing. Background technique [0002] High-intensity focused ultrasound therapy is a new type of non-invasive treatment method, which is increasingly favored by people. At present, it is a worldwide problem to accurately measure tissue temperature for focused ultrasound therapy, and all countries are looking for accurate measurement methods for tissue temperature for focused ultrasound therapy. It has been confirmed that in ultrasound therapy, there is a known correlation between the gray scale change of the B-ultrasound image at the treatment point and the tissue temperature change. By observing the gray-scale change of the B-ultrasound image at the treatment point, the corresponding temperature change of the treatment point can be obtained. Know...

Problems solved by technology

Therefore, doctors are required to have a very high level of image recognition to accurately judge the therapeutic effect, which is not only time-consuming, but also has a large error; however, the evaluation of the therapeutic effect of high-intensity focused ultrasound is the key to judging the therapeutic effect. All are judged by the doctor based on the gray level change of the B-ultrasound image. The judgment error is very different due to the difference in the experience of the doctor and the difference in the display. Bring greater difficulty, directly affect the curative effect of treatment
