Problems solved by technology

[0002] The existing PACS system, because the image display uses the early graphics device interface GDI (GraghicDeice Interface), due to the functional limitations of GDI, the hardware acceleration of image operations commonly used by doctors on the PACS client cannot be realized; in the original CR / In the DR / CT image display and image processing technology, the CPU of the PC is used for image processing, and then the video memory is transferred to wait for display. However, since the CPU is also responsible for the operation of other processes, the CR / DR images commonly used by doctors have a large amount of data Therefore, the CPU is operating at full load, which reduces the film output rate and affects the doctor's work efficiency; in addition, the default lighting processing of the system fixed pipeline in the original technology has a slow display speed, which will negatively interfere with the doctor's reading; The display body position setting in the original technology lacks flexibility and is not conducive to later expansion of custom operations

Abstract

The invention relates to a method and special equipment for quickening CR / DR / CT graphic display and graphic processing by utilizing a graphic processing unit (GPU), belonging to the field of medical graphic display and comprising a personal computer (PC), a CR / DR workstation or a picture archiving and communication system (PACS) server. The PC is connected with the CR / DR workstation or the PACS server. The invention utilizes the general computing power of the novel GPU to realize the quick display of CR / DR / CT graphic, accomplishes the graphic display and processing function by utilizing the GPU, and provides a processing method for dividing and splicing graphics. Different from the graphic device interface (GDI) used by the prior PACS, the method sufficiently utilizes the general computing power of the GPU, thereby freeing the GPU from heavy calculation of graphic processing to focus on processing of data communication and data safety and improving the efficiency of the system.
