Solution background introduction:
With the rapid development of the medical industry, medical imaging systems have received widespread attention. Medical imaging systems (PACS) convert medical instrument image data into computer digital forms, and complete the collection, storage, and management of image information through high-speed computing equipment and communication networks The functions of image processing, processing, and transmission enable the effective management and full use of image data, which has led to the widespread use of ultrasound imaging workstations, CT imaging workstations, X-ray machine imaging workstations, and nuclear magnetic imaging workstations. The key of the system is to collect almost perfect images of medical equipment such as B-mode, CT, X-ray machines, nuclear magnetic resonance, and endoscopes, and present them to the doctors to improve the doctor's judgment of the condition.
For standard video capture such as B-ultrasound and endoscope, there are many types of image capture cards on the market, the image quality varies greatly, and the prices are not the same. It makes it very difficult for customers to choose. The image quality of the card wastes a lot of time and effort. For non-standard CT, X-ray machines, and nuclear magnetic field, it is even more difficult to select an image acquisition card, because such card acquisition requirements are high, research and development is difficult, The image quality is fine and expensive. Users can only purchase products through imported or very few domestic manufacturers, which is restricted in selectivity. It has been difficult to reduce product costs for a long time. In addition, the parameters of medical equipment are uncertain, and models are different. The selection of the acquisition card is even more difficult, and the customer's choice is very painful, so that the delay of the project causes a great loss.
Scheme system architecture diagram:
Mayfield M1620 dual HD video capture card is suitable for high precision, high resolution image processing, streaming media, medical image equipment (such as ECT, standard and non-standard color ultrasound, etc.), radar equipment and other fields. At the same time, image processing such as scaling and de-interlacing, which consumes CPU time, is completed in the FPGA, which greatly reduces the burden on the CPU. At the same time, the high-efficiency DMA transfer method further frees the CPU's ability, so that the CPU can focus on the work specified by the user. And 10-bit sampling precision AD converter is used to ensure rich picture details, high signal-to-noise ratio, and minimize the appearance of color fringing. At the same time, the implementation of scaling and motion adaptive de-interlacing technology in FPGA further guarantees the picture quality. Mefeite clear video capture card can achieve high quality and low cost access to different types of video while maintaining the original high definition image quality.
