Detailed introduction to the technology of improving the image quality and processing speed of handheld ultrasound machines

The technology of improving the image quality and processing speed of handheld ultrasound machines mainly involves several aspects.

First, the technology of improving image quality includes the use of high-frequency probes, which can emit more ultrasound waves, increase the penetration depth and signal reception strength. At the same time, changing the angle of the probe and optimizing the position of the probe are also effective methods, which can change the propagation path of ultrasound waves in the tissue and reduce signal attenuation. In addition, in order to reduce noise, low-pass or high-pass filters can be used, the detection gain can be optimized, and the scanning time can be controlled. Increasing the sampling point density, selecting the appropriate detection frequency, and adjusting the grayscale mapping function can also help improve the resolution and contrast of ultrasound images.

Secondly, the technology of improving processing speed mainly involves optimizing the analog front end (AFE) for portability, which includes the use of low-power and highly integrated components to reduce battery life and size while maintaining excellent image quality. In addition, the use of more efficient digital processing algorithms and faster hardware are also key to improving processing speed.

In general, these technologies work together to significantly improve the image quality and processing speed of handheld ultrasound machines, thereby improving the accuracy and efficiency of diagnosis. Please note that the specific implementation of these techniques may vary between devices and manufacturers, so in actual applications they need to be selected and optimized based on specific circumstances.
