Method and device for measuring human tissue quasi-elastic coefficient and elasticity

Abstract

The invention discloses a method for measuring a human tissue quasi-elastic coefficient. The method adopts a simplex optimizing method to determine the quasi-elastic coefficient of a human tissue, andreduces nine three-dimensional elastic coefficients to three quasi-elastic coefficients (for example, in a two-dimensional ultrasonic patient treatment plane or detection, four elastic coefficients are reduced to two quasi-elastic coefficients), and can save the calculation time. The invention also provides a human tissue quasi-elastic coefficient measurement method on the basis of the quasi-elastic coefficient measurement method, which adopts a secondary imaging method to measure relative change of the human tissue quasi-elastic coefficient, can thoroughly change the defects of ultrasonic images depending on the precision of elastic image instruments; change of the human tissue structure can be accurately determined according to the measured change; in addition, the invention also provides an ultrasonic detector or detection device matching the human tissue quasi-elastic coefficient, expensive imaging devices can be avoided, and the ultrasonic detector or detection device is low in price; and the detector can be accepted by public, and can be promoted and applied.

Description

technical field [0001] The invention relates to the detection field, in particular to a method and equipment for measuring the quasi-elastic coefficient of human tissue and the change of the quasi-elastic coefficient. The present invention also proposes a set of patient treatment plans based on ultrasound images. Based on this plan, we can make patient data plans every day, and we can make patient data plans precisely as the tumor size changes. Background technique [0002] Currently, there are elastographs (such as GE, Mindray) to measure the absolute elastic coefficient of human tissue, but such elastographs generally require expensive and high-precision imaging equipment, which are not accepted by doctors clinically, and the market volume is not large. Big. [0003] The existing quasi-elastic coefficient measurement methods generally use nine three-dimensional elastic coefficients or two-dimensional four elastic coefficients for measurement and calculation, which takes a...

Problems solved by technology

[0002] Currently, there are elastographs (such as GE, Mindray) to measure the absolute elastic coefficient of human tissue, but such elastographs generally require expensive and high-precision imaging equipment, which are not accepted by doctors clinically, and the market volume is not large. Big

[0003] The existing quasi-elastic coefficient measurement methods generally use nine three-dimensional elastic coefficients or two-dimensional four elastic coefficients for measurement and calculation, which takes a long time to calculate, and because the absolute elasticity of human tissue is a difficult quantity to determine , even if the absolute elastic coefficient can be obtained, it is not easy to distinguish the difference in elastic coefficient between normal tissue and diseased tissue (such as human calcification or benign tumor and tumor density are very similar)

[0004] It can be seen that the above-mentioned existing elastic coefficient measurement method and equipment obviously still have great inconvenience and defects, and a theoretical breakthrough is urgently needed to solve this problem
