Problems solved by technology

However, in order to realize the elastography method, a certain pressure must be applied to the inspected part. The existing technology only achieves success in applying pressure to the superficial part of the cavity, and it is completed by applying pressure on the deeper part. The elastography method has not been reported in the relevant literature

Abstract

The present invention relates to an intracavitary ultrasonic hardness imaging method. Said method includes the following steps: creating and mounting high-frequency ultrasonic transducer with pressure-applying water bag and its integrated ultrasonic hardness imaging conduit which can be axially moved; utilizing said pressure-applying water bag to apply pressure to inner wall of tested object, according to two different applied pressures on some point calculating pressure variable quantity of said point; and respectively obtaining thickness variable values of said detected point when the applied pressures are different; according to said thickness variable values calculating hardness value and utilizing color hardness graph to make display. Besides, said invention also provides a body cavity ultrasonic hardness imaging apparatus for implementing said method.

Description

technical field [0001] The invention relates to a technology for obtaining information in a body cavity, and relates to the acquisition of hardness parameters of the body cavity wall of a human body and an animal, a color imaging display method and an ultrasonic diagnostic instrument. Specifically, it is a method of using an ultrasonic hardness imaging catheter to enter the body cavity to obtain and analyze the stress-strain relationship of the inner wall tissue of the body cavity, so as to obtain the hardness index of the wall tissue of the body cavity or calculate the Young's modulus of the wall tissue according to the corresponding formula, and then proceed accordingly. The computer color coding method directly displays the overall hardness and hardness distribution information of the digestive tract wall tissue. The obtained information is beneficial to assist medical research and provide reference for clinical diagnosis. The invention also relates to an ultrasonic hardne...
