Abstract

A passage convexity diagnostic device of a probe control module of a diasonograph is characterized in that the device comprises a power supply source, a DC signal generation device, a high voltage switch, a front-end control module and a display module. The power supply source is respectively connected with the DC signal generation device, the high voltage switch, and the front-end control module. The DC signal generation device and the front-end control module are respectively connected with the high voltage switch connected with the input end of the probe control module which needs to be tested; the input end of the probe control module which needs to be tested is connected with the display module.

Description

technical field [0001] The invention relates to the technical field of ultrasonic diagnosis, in particular to a diagnostic device for channel connectivity of a probe control module of an ultrasonic diagnostic instrument. Background technique [0002] As shown in Figure 1, the existing ultrasonic diagnostic equipment is mainly composed of five parts: a probe control module, a receiving module, a transmitting module, a beamformer, and a digital signal processing module. The specific implementation principle is as follows: the pulse sent by the transmitting module is added to the chip of the probe array element, and the ultrasonic pulse sent by the chip propagates in the soft tissue of the human body. When the ultrasonic wave hits the human body tissue, it is reflected, and the reflected echo It is amplified and processed by the receiving module, and the processed signal is uploaded to the computer through the PCI card, and then the image is displayed on the monitor. [0003] ...
