Ultrasonic three-dimensional mixed and superposed volumetric rendering processing method based on GPU (Graphic Processing Unit)

Abstract

The invention discloses an ultrasonic three-dimensional mixed and superposed volumetric rendering processing method based on a GPU (Graphic Processing Unit). In the method, the rendering data is determined in a manner of agent cube, and a two-dimensional image sequence is selected for drawing. In the method, the GPU is not required for supporting the volumetric data texture, and the method can be realized on a cheaper GPU; the method can be used for realizing real-time volumetric data drawing in any visual angle, and a three-dimensional image can be rotated freely in 360 degrees according to the clinical requirements of doctors, which facilitates multi-angle observation.

Description

technical field [0001] The present invention relates to medical ultrasonic imaging technology, in particular to an ultrasonic three-dimensional hybrid superposition rendering processing method using GPU (Graphics Process Unit) graphics processing technology. Background technique [0002] Three-dimensional imaging is the main development direction of medical imaging technology in recent years. The development of tomographic imaging to three-dimensional volume imaging is the general trend of medical imaging, and it is a new development stage used to nondestructively display the internal morphological structure or function of the human body. [0003] The 3D ultrasound imaging technology reconstructs the traditional two-dimensional ultrasound of multiple or multiple sections to obtain volume data, and draws and processes the volume data to obtain a clear three-dimensional B-ultrasound diagnostic image, which makes the doctor's clinical diagnosis based on the traditional method. ...

Problems solved by technology

In terms of volume data rendering, the previous processing method was implemented by the CPU of a general-purpose computer. Due to the large amount of calculations in the 3D imaging processing of ultrasound images, a high-performance and high-priced PC system is required, and the processing capabilities of the processing system of the ultrasound diagnostic instrument itself are often not enough. Therefore, it is necessary to collect the ultrasonic image of the ultrasonic diagnostic instrument through a high-speed data acquisition card and send it to an external PC workstation system for processing and displaying a three-dimensional image

The whole system consists of an ultrasonic diagnostic instrument, a video acquisition card, and an external PC workstation. Not only is the system complex, expensive, poor in real-time performance, and inconvenient to operate, but also the image quality is not satisfactory due to the signal loss of image acquisition.
