Probe automatic correction method and system for ultrasonic diagnostic equipment

Abstract

The invention provides an automatic probe correcting method and system of ultrasonic diagnosis equipment. The correcting method includes the following steps that S1, the number of times for scanning is determined according to the primitive number N of a current probe, wherein the number of times for scanning is equal to the primitive number N; S2, a trigger signal for starting scanning is received, and multiple echo signals corresponding to all primitives are obtained through scanning and processed correspondingly to obtain an original specific value sequence corresponding to all the primitives; S3, the original specific value sequence is screened to obtain an ideal specific value sequence corresponding to all normal primitives, and characteristic parameters of all the primitives in the probe are calculated based on the original specific value sequence and the ideal specific value sequence; S4, according to the characteristic parameters, emitting voltage of all the primitives in the probe are adjusted correspondingly. The automatic probe correcting method and system automatically correct the probe in real time, avoid influence on probe correction by fatigued and damaged primitives and are high in correction accuracy and efficiency and low in cost.

Description

technical field [0001] The invention relates to the technology in the field of ultrasonic medical treatment, in particular to a method and system for automatically correcting a probe of ultrasonic diagnostic equipment. Background technique [0002] Ultrasonic diagnostic instrument is an important tool for modern medical diagnosis, which has brought a leap forward to the disease diagnosis technology in the medical field. Doctors can make diagnosis and treatment judgments based on the image features output by the ultrasonic diagnostic instrument. For example, the typical feature of kidney stones is the highlight in the image with shadow trailing, etc., so the final imaging quality of the ultrasonic diagnostic instrument is very important for diagnostic accuracy. As we all know, the imaging quality of an ultrasonic diagnostic instrument is closely related to the ultrasonic transmitter (probe) and the transmitting circuit. The characteristics of the probe, such as sensitivity an...

Problems solved by technology

However, for a certain type of probe, the same parameters stored in the chip must be applied to all probes, and this method cannot overcome the deviation between probes; for the differences in the transmitting circuits of probes with element fatigue or damage, this solution cannot to correct

In addition, this kind of hardware correction solution is not fully automated, it requires a certain amount of manual assistance, which is not only inefficient, but also error-prone, which increases additional labor costs, and its own hardware solution also increases a certain cost
