Abstract

The invention provides a convex array probe performance testing method and device, and the method comprises the steps: controlling a convex array probe to carry out first motion, and determining the initial posture of the convex array probe according to the parameter value of the target parameter of an ultrasonic signal received by a first target array element in the first motion process of the convex array probe, wherein the initial attitude is an attitude in which the distance between the first target array element and the reflection target is closest and the array element arrangement direction of the convex array probe is parallel to the first plane; controlling the convex array probe to perform second motion in the initial attitude, and determining the test pose of the convex array probe according to the parameter value of the target parameter of the ultrasonic signal received by the second target array element in the second motion process of the convex array probe, wherein the test pose is the pose which enables the distance between the second target array element and the reflection target to be consistent, and the ultrasonic signal emitted by the second target array element is perpendicular to the tangent plane of the incidence position of the ultrasonic signal in the reflection target; and carrying out performance test on the convex array probe according to the test pose.

Description

technical field [0001] The present disclosure relates to the technical field of probe testing, and more specifically, the present disclosure relates to a performance testing method of a convex array probe and a performance testing device of a convex array probe. Background technique [0002] The medical ultrasonic probe is the core component of diagnostic ultrasonic equipment. It uses the piezoelectric effect to convert the electrical signal transmitted by the ultrasonic system into an ultrasonic signal and emit it. It can also convert the returned ultrasonic signal into an electrical signal and transmit it back to the ultrasonic system. imaging. The acoustic performance of the ultrasound probe has a great influence on the image quality, so the detection of its acoustic performance is particularly important. [0003] The surface of the probe contains multiple array elements (the number of array elements can be 64, 128, 256, etc.), and each array element can be independently...
