Method for adjusting plot ratio based on ultrasonic hardware

Abstract

The invention provides a method for adjusting a plot ratio based on ultrasonic hardware. The method comprises the following steps: S01, when software issues a target plot ratio to a main control chip, calculating an extreme point, an upper limit range and a lower limit range of the plot ratio by a main control chip under the change of a plurality of hardware parameters according to a formula and a default initial value; S02, arranging the plot ratio results obtained in the step S01 according to the plot ratio from small to large, and recording and storing the plot ratio results together with hardware parameters corresponding to each plot ratio in a hardware cache chip; and S03, realizing the required plot ratio by adjusting hardware parameters. According to the invention, the intelligent method for realizing the 3D image multi-plot ratio by automatically adjusting the data volume and time consumption of the image through hardware is realized. According to the method, hardware processing time is shortened, intelligent and variable plot ratio is achieved, an external scanning device is not changed, the positioning precision of an ablation catheter can be maintained, and the display refresh rate of a 3D image can be increased.

Description

technical field [0001] The invention belongs to the technical field of micro-ultrasonic detection, and relates to an intelligent ultrasonic hardware system with multiple volume ratios. Background technique [0002] The ultrasound host acquires ICE probe data and converts it into a 2D section image of human tissue; every time the ICE catheter rotates an angle, the host generates a 2D section image; the 3D reconstruction module restores and reconstructs all 2D section images into 3D images of human tissue body imaging. [0003] In ablation surgery, the 3D module is responsible for the reconstruction of the three-dimensional structure of tissues (heart, blood vessels) in the body, as well as the position tracking and display of the ablation catheter in the above-mentioned 3D body structure; the refresh rate of the three-dimensional structure of the tissue displayed on the image interface is called the volume rate . The higher the refresh rate, the more accurately the position...

Problems solved by technology

[0005] The problems of the above two methods: increase the angle scanning speed, the angle step is smaller, and the positioning is more accurate, but the increased number of 2D slices will make the display refresh slower; reduce the angle scan speed, although the reduced number of 2D slices will make the display refresh Faster, but less precise positioning
