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

Embodiment Construction

[0019] The present invention will be described in detail in conjunction with embodiments.

[0020] SLN_Phy (physical scanning line number), Fs (sampling clock), N (sampling resolution), DataRate (data transfer rate), Thard (hardware level time consuming), Tsoft (software level elapsed time), Vol_Rate (3D image on-screen display refresh rate), Depth (distance), V (acoustic physical quantity).

[0021] 2D slice data displayed on the screen of a scanning line by the splicing together, show greater number of scanning lines, more delicate 2D image.

[0022] Display scan line from the process after the scanning line by the physical software algorithms. Is defined as the number of display scanning lines SLN_Dis, the number of physical scan lines SLN_Phy, the scanning line gain SLN_Gain, then:

[0023] SLN_Dis = SLN_Phy * SLN_Gain

[0024] Physical scanning line generated by the ultrasound apparatus is sampled at the data clock driver, if the sampling resolution of N (bit), the sampling c...

Abstract

The present invention provides a method for adjusting the volume ratio based on ultrasonic hardware, which includes the following steps: Step S01: When the software sends the target volume ratio to the main control chip, the main control chip will calculate the volume ratio based on the formula and the default initial value. Under multiple hardware parameter changes, the extreme points and upper and lower limit ranges of the floor area ratio; Step S02: Arrange the floor area ratio results obtained in step S01 in order of the floor area ratio from small to large, together with the hardware parameters corresponding to each floor area ratio Record and store in the hardware cache chip; Step S03: realize the required volume ratio by adjusting the hardware parameters, the present invention automatically adjusts the image data amount and time consumption by the hardware to realize the intelligent method of 3D image multi-volume ratio. The hardware processing time is reduced, so that the volume ratio can be intelligently variable, and the external scanning device is not changed, which can not only maintain the positioning accuracy of the ablation catheter, but also improve the display refresh rate of the 3D image.

Description

Technical field [0001] The present invention is in the field of micro-ultrasonic testing, an ultrasonic relates to intelligent hardware system of a multi-volume ratio. Background technique [0002] ICE acquiring ultrasound probe data and the host of the image into 2 dimensional slices of human tissue surface; a rotation angle of each of the ICE catheter, the host generates a 2D slice FIG; 3D reconstruction module all 2D image slices of the human tissue reconstruction 3D imaging. [0003] Reconstruction of three-dimensional structure in the ablation procedure, 3D module is responsible for body tissue (heart, blood vessels), and the position of the ablation catheter tracking in the above-described 3D structure and a display; refresh rate of three-dimensional structure of the tissue image displayed on the interface is called the volume ratio . The higher the refresh rate, the position of the ablation catheter tracking more precisely the trajectory of the continuous display, the more...
