This system improved the existing IWEB in the framework of PACS client image processing, medical image based on the service WEB completion port model. To realize the fast loading images with high concurrency, compared with the traditional WEB PACS, this system has the advantages of no client without plug-in installation, at the same time in the transmission and processing performance image has been greatly improved.展开更多

The system uses the Cortex-M4 as the core of the STM32F407ZGT6 as the control core, the use of OV2640 as an image sensor to collect images, and the collection of image files stored in the SD card for subsequent image processing to achieve the goal of rail adjustment to lay the foundation. The experimental results show that the image acquisition is stable and refiable and the collected images are clear and meet the design requirements.展开更多
