Qi Yang proposed ultrasonic diagnosis solution based on i.MX8M Mini. Ultrasonic diagnostic instrument, also known as ultrasonic medical imaging equipment, is an instrument that uses the reflection, refraction and diffraction of ultrasound to probe the internal structure of the human body. Due to the non-invasive, non-invasive, economical and practical features of ultrasound diagnosis and wide range of applications, ultrasound diagnostic instruments have also become one of the commonly used medical devices in the medical field at present.
Ultrasonic Diagnostic Instrument
Ultrasonic diagnostic instrument mainly consists of the device host, ultrasonic probe(transducer) and peripheral equipment. The ultrasound probe is a key component of ultrasound imaging equipment, whose task is to convert electronic signals into ultrasound information or to convert ultrasound signals to electronic signals. The host part mainly receives the electronic signals transmitted by the probe and stores, processes, analyzes and display them on the display; peripheral devices include printers, foot pedals, etc.
When the host part works, the ultrasonic probe transmits the received signal to the pre-amplification circuit, and after amplification, the analog signal is convert to digital signal through A/D conversion circuit, then through the synthesis processing of digital circuit and digital scan converter,and finally the processed image video is displayed on the display. The host involves signal processing, encryption processing, signal transmission, power supply, etc. In terms of hardware, ARM processor can be used as the system core to complete timing control, launch driver, signal extraction, data transmission control. NXP i.MX8M Mini processor has high processing capability, 2D 3D built-in gas pedal, rich interface resources, which can replace FPGA and ASIC for medical ultrasound equipment solutions.
