Embodiment Construction

[0030] In this embodiment, the design of an ultra-thin time gain compensation (TGC) device is mainly realized by using a touch sensing device.

[0031] Figure 4 It is the functional block diagram of the touch TGC module, which is mainly composed of a touch sensor and a corresponding processor. The touch sensor is mainly used to sense finger movements such as touching, removing, and sliding; the processor mainly processes the output signal of the touch sensor, and transmits it to the host computer after real-time processing.

[0032] Figure 5 The structural block diagram of the control device of the touch TGC module is given, which mainly consists of the following four parts:

[0033] (1) Surface film 51, which is made of insulating and wear-resistant material, is mainly used to protect the touch sensor, and there is a silk screen on it to indicate the TGC touch area;

[0034] (2) touch sensor 52, which can be a one-dimensional strip sensor or a two-dimensional sensor surf...

Abstract

The invention discloses a touch time gain compensation control apparatus used in an ultrasonic diagnostic apparatus and a hand-slip type time gain compensation curve setting method. The touch time gain compensation control apparatus comprises a touch inductor used for inducing touch action and a processor which is used for processing an output signal from the touch inductor and sending the processed signal to a host computer. The method comprises the steps as follows: a finger slips over a touch area of a touch time gain compensation device; the touch inductor identifies the slipped position by the finger and outputs a single corresponding to the position; the processor processes the signal from the touch inductor and sends the processed signal to the host computer; and the host computer draws a time gain compensation curve according to the received signal. The touch time gain compensation device and the time gain compensation curve setting method provided by the embodiment of the invention have low cost, high reliability and convenient operation.

Description

technical field [0001] The invention relates to a time gain compensation device and a time gain compensation curve setting method, in particular to a touch-type time gain compensation control device and a time gain compensation curve setting method for an ultrasonic diagnostic instrument. Background technique [0002] Time Gain Compensation (TGC) device is one of the important components of ultrasonic diagnostic equipment. In the prior art, a slide potentiometer (slide potentiometer) is used to realize the TGC device, wherein the block diagram of each segment of TGC is as follows figure 1 . figure 2 It is the appearance diagram of eight-segment TGC, which uses 8 sliding potentiometers. When the slider of the sliding potentiometer is at the bottom end (that is, the GND terminal), its output voltage is almost zero; when the slider is at the top end (that is, the VCC terminal), its output voltage is VCC. Assuming that the total resistance value of the sliding potentiometer ...
