Application of Industrial computer in B-ultrasonic Diagnostic instrument
With the development of economy and the progress of science and technology, the material living standard of the people has been continuously improved, and the demand for medical treatment has also greatly increased, which has stimulated the rapid development of medical devices. Ultrasonic imaging equipment with high sensitivity, high application, low cost and wide application has been rapidly promoted with its unique advantages. Especially with the development of high-speed, large-capacity and intelligent industrial computer technology, B-ultrasonic diagnostic instrument has been widely used in hospitals at all levels.

With the rapid development of computer information technology and the need of clinical diagnosis and treatment, the demand for the quality of B-ultrasound image is higher and higher. The embedded industrial computer has the advantages of small size, rich serial port, low power consumption, wide temperature and high stability, which effectively improves the overall performance and competitive advantage of the B-ultrasonic system.
The working principle of B-ultrasonic diagnostic instrument:

The B-type ultrasonic diagnostic instrument uses pulse echo imaging technology, it is mainly composed of main control circuit, transmitting circuit, receiving circuit (high frequency signal amplifier, video signal amplifier), scanning generator, image display (electron gun, deflection system, fluorescent screen) and transducer.

The main control circuit, also known as synchronous trigger signal generator, periodically generates synchronous trigger pulse signals, triggering the transmitting circuit and the time-based scanning circuit in the scanning generator respectively.

When triggered by a synchronous signal, the transmitting circuit generates a high-frequency electric pulse to stimulate the transducer.

The receiving circuit receives the ultrasonic information reflected by the examined tissue of the human body, which has the following main processes: (1) amplifying and logarithmic compression of the high-frequency ultrasonic signal; (2) detecting the high-frequency ultrasonic signal and converting it into a video signal; (3) amplifying the video signal; and (4) displaying the amplified video signal on the display.

After the transducer converts the echo signal into high-frequency electrical signal, the video envelope signal detected by the detector is amplified and processed by the video signal amplifier, and then added to the grid of the display for brightness modulation.

The scanning generator generates the scanning voltage, which makes the electron beam scan according to a certain rule, and the cross-section image is displayed on the display.

With the continuous improvement of medical devices, higher requirements have been put forward for data acquisition, analysis, storage and display. With the advantages of small size, powerful performance, low power consumption and multi-serial port, embedded industrial computer is favored by many medical equipment suppliers at home and abroad, and is well received in many project applications. According to the performance requirements of medical devices, industrial computer products have strong computing power and more stable and reliable performance, low power consumption, no pollution to achieve better environmental protection requirements.

The embedded industrial computer effectively aims at the special needs of the medical industry, with the characteristics of small size, high reliability, low power consumption, multi-serial port and so on, which effectively promotes the development of medical devices to intelligence, specialization, miniaturization and environmental protection.
