Background introduction of the program:
Today, with the rapid development of medical industry, medical imaging system has received extensive attention. Medical imaging system (PACS) converts medical instrument image data into computer digital form, and completes the functions of image information collection, storage, management, processing and transmission through high-speed computing equipment and communication network, so that image data can be effectively managed and fully utilized, thus promoting the widespread use of ultrasound imaging workstations, CT imaging workstations, X-ray imaging workstations, and nuclear magnetic imaging workstations. The key to the system is to collect the images of medical equipment such as B-ultrasound, CT, X-ray, nuclear magnetic, endoscope, etc. almost perfectly, present them to doctors, and improve doctors' judgment of the condition.
For standard video acquisition such as B-ultrasound and endoscope, there are many types of image acquisition cards on the market, with great differences in image quality and prices, which makes it very difficult for customers to choose. They can only judge the image quality of the acquisition card by borrowing the card for testing, which wastes a lot of time and energy. For non-standard CT, X-ray machines, and nuclear magnetic resonance, the selection of image acquisition cards is even more difficult, because such cards have high acquisition requirements, high R&D difficulty, fine image quality, and high prices. Users can only purchase products through imports or very few domestic manufacturers, which is restricted in selection. For a long time, it has been difficult to reduce product costs. In addition, the parameters of medical equipment are uncertain and the models are different, making it even more difficult to choose an acquisition card. Customers are very painful to choose, resulting in great losses caused by project delays.

Purplelec solution:
Purplelec 48AHG dual-channel high-definition video acquisition card is suitable for high-precision and 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 deinterlacing that consumes CPU time is completed in the FPGA, which greatly reduces the burden on the CPU. At the same time, the high-efficiency DMA transmission method further liberates the CPU's capabilities, allowing the CPU to focus on the work specified by the user.
And the use of 10-bit sampling accuracy AD converter ensures rich picture details, high signal-to-noise ratio, and minimizes the appearance of color fringing. At the same time, the scaling and motion adaptive deinterlacing technology implemented in the FPGA further ensures the image quality. Bode's high-definition video capture card can achieve high-quality and low-cost access to different types of videos required, while continuing to maintain the original high-definition image quality.
