Method and device for adjusting time gain compensation function through touch screen

Abstract

The embodiment of the invention discloses a method and device for achieving the function of adjusting time gain compensation through a touch screen. The method for achieving the function of adjusting the time gain compensation through the touch screen comprises the steps that a time gain compensation control interface is opened according to a touch instruction of a user, the time gain compensation input by the user is obtained through the time gain compensation control interface on the touch screen, and setting of a device is changed according to the time gain compensation input by the user. According to the method and device for achieving the function of adjusting the time gain compensation through the touch screen, the TGC input by the user is obtained through the TGC control interface on the touch screen, and thus TGC setting of the device is changed. When the technical scheme is compared with a technical scheme for adjusting TGC in the prior art, due to the fact that the TGC set by the user is input through the TGC control interface on the touch screen, the user only needs to touch the touch screen, specialized keys are not needed, and the phenomenon that ageing happens after the keys are used for a long time is avoided; meanwhile, the cost for addition of key hardware is reduced, and the problem that the function of adjusting the TGC cannot be conveniently improved is solved.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a method and a device for adjusting a time gain compensation function through a touch screen. Background technique [0002] Ultrasonic testing technology has been widely used in the field of medical testing. The function of Time Gain Compensation (TGC, TimeGainCompensation) in ultrasonic testing equipment is that, because ultrasonic waves will cause energy loss such as reflection and absorption when propagating in human tissue, so The intensity of ultrasonic waves transmitted into the body decreases with increasing depth. Similarly, for the acoustic reflection interface with the same reflection coefficient, the echo signal received by the transducer will also be different due to the difference in depth. In order to make the waveform amplitude displayed on the display of the ultrasonic diagnostic equipment or the black and white contrast of the image reflect the re...

Problems solved by technology

[0003] In the prior art, the adjustment of TGC is controlled by the keys on the keyboard. As time goes on, the keys are easy to age, resulting in the failure of this function and inaccuracy. This problem can only be solved by repairing or replacing the keyboard; TGC’s The adjustment is realized by the electronic device on the keyboard, and it is not easy to upgrade. When there are new requirements, it is not easy to adapt, and the hardware needs to be changed to adapt to the new requirements; the adjustment of TGC is not flexible enough. To adjust TGC, you need to pass Each button slides the slider left and right, especially sometimes if you want to adjust the overall TGC, you need to adjust multiple sliders or even all the sliders, which is not convenient enough to operate
