Automatic Calibration Method and System for Scanning Accuracy of Ultrasonic Probe

Abstract

The invention provides an automatic ultrasonic probe scanning precision calibration method and system. The method comprises the steps of emitting pulse signals to an ultrasonic probe through a plurality of signal transmission channels, and recording the emission time of each pulse signal passing through the corresponding signal transmission channel; reflecting the pulse signals through the ultrasonic probe to form reflection signals after the pulse signals reach the ultrasonic probe; receiving the reflection signals which are returned through each signal transmission channel and correspond to the emitted pulse signals respectively, and recording the receiving time of each reflection signal; acquiring signal transmission compensation time difference in the transmission channels according to the emission time of the pulse signals in the transmission channels and the receiving time of the reflection signals; automatically conducting alignment compensation on the channels according to the compression time difference. By the adoption of the method and system, clinical diagnosis convenience and using efficiency of ultrasonic imaging equipment are improved, and ultrasonic diagnosis image quality is improved.

Description

technical field [0001] The invention belongs to the field of ultrasonic diagnostic imaging, and relates to an automatic calibration method and system for the scanning accuracy of an ultrasonic probe. Background technique [0002] Ultrasound imaging equipment has become one of the most widely used clinical diagnostic tools because of its non-invasive, real-time, convenient operation, and low price. [0003] combine figure 1 as shown, figure 1 It is a basic composition block diagram of ultrasonic diagnostic equipment in the prior art. The ultrasonic imaging equipment is at least composed of an ultrasonic host and an ultrasonic probe. The ultrasonic host includes a transmitting module, a receiving module, a transmitting and receiving switch module, and a control and data processing module. 1. Host computer; the transmitting module transmits ultrasonic signals through the probe at specific time intervals; the receiving module receives echo signals through the probe and synthes...

Problems solved by technology

[0006] However, in the actual application of ultrasound imaging equipment, the time interval will change due to many reasons

For example: in the actual use of the ultrasonic probe, a new time interval is generated due to its surface wear and deformation; during the cross-use of the ultrasonic host and the ultrasonic probe, the difference between the lengths of the electrical pulse channels of different hosts produces new time intervals. The time interval caused by the above-mentioned various reasons cannot be processed by the existing ultrasonic diagnostic equipment, which will affect the imaging quality and have a great impact on the efficiency of clinical use
