Method and system for controlling focus position and image depth in ultrasonic diagnostic instrument

Abstract

The invention discloses a control method and system for a focus position and image depth in ultrasonic diagnostic equipment. The invention provides a working flow customizing method and device for the ultrasonic diagnosis equipment. The method comprises the following steps that S1, an upper adjustment limit and a lower adjustment limit of the focus position of the ultrasonic diagnostic equipment are acquired; S2, a rolling signal of a module ball is received, and a focus is controlled to move upwards or downwards according to the rolling signal; S3, the current position of the focus is identified, whether the current position of the focus reaches the upper adjustment limit or the lower adjustment limit is judged, if yes, S4 is executed, and if no, S2 is executed; and S4, the image depth of the ultrasonic diagnostic equipment is increased or reduced according to the rolling signal of the module ball. According to the method, adjustment control of two parameters is achieved by a single control, so that an operation interface of the ultrasonic diagnostic equipment is simplified, the cost of the equipment is further lowered, scanning of a user is more efficient, and certain special clinical applications are adapted.

Description

technical field [0001] The invention relates to the field of ultrasonic diagnostic equipment, in particular to a method and system for controlling focus position and image depth in an ultrasonic diagnostic instrument. Background technique [0002] Ultrasonic diagnosis (Ultrasonic Diagnosis) is a diagnostic method that applies ultrasonic detection technology to the human body, which finds diseases by measuring the data and morphology of physiology or tissue structure. Most of the existing ultrasonic diagnostic instruments include a transmitting focusing module and a receiving focusing module, wherein the transmitting focusing module usually adopts a static focusing technology with fixed focus. parameters to control the emission focus. Among them, the emission focus position can adjust the physical position of the real focus of the emitted ultrasonic beam, which is determined by the area of ​​interest to the user. In addition, due to the needs of examining different human org...

AI Technical Summary

Problems solved by technology

[0003] Existing ultrasonic diagnostic instruments are provided with knobs or buttons for adjusting the image depth and the focus position respectively on the operation keyboard or the user interface, that is, the adjustment of the focus position and the image depth is respectively realized through two controls. The adjustment control is inconvenient and error-prone during the adjustment process, which is not conducive to the user's quick and convenient operation, especially in some special clinical departments, such as anesthesia room, operating room, etc.
