Abstract

The invention discloses an embedded real-time high-definition medical ultrasound imaging system of an integrated graphics processing unit. The system adopts embedded equipment of the integrated graphics processing unit for achieving medical ultrasound imaging, by adopting an improved high-definition imaging algorithm, the calculation process is suitable for a computing environment of the graphics processing unit, and therefore the image quality of medical ultrasound imaging is improved, and the imaging frame rate of medical ultrasound imaging is increased. Compared with a traditional portable medical ultrasound imaging system, the adopted integrated graphics processing unit embedded system has a high parallel computing capacity, complicated calculation of the high-definition medical ultrasound imaging algorithm can be completed within a short period of time, and real-time high-definition medical ultrasound imaging can be presented. Accordingly, the phenomenon that minimum variance wave beams form high-definition ultrasound imaging is achieved, and a high-definition medical ultrasound image is output in real time on the embedded system. The embedded system of the integrated graphics processing unit is low in price, high in practicability and high in cost performance.

Description

technical field [0001] The invention belongs to the field of medical ultrasound imaging, and completes the core processing module of a portable high-definition medical ultrasound imaging device based on a high-performance embedded computing platform integrating a graphic processing unit. Background technique [0002] In the medical ultrasound imaging system, the physical array element emits ultrasound and receives the echo signal, and then the echo signal data is converted into image data by the imaging algorithm in the computing unit and displayed. The traditional time-lapse superposition imaging algorithm is usually implemented on the central processing unit CPU, but the huge imaging data and complex calculation process of the high-definition imaging algorithm make the traditional CPU unable to meet its demand for high-performance computing. [0003] In recent years, the frequency of CPUs has been continuously increasing, and the number of CPU cores on a single chip has al...
