【摘要】 详细介绍了利用X-射线图象增强管和普通工业CCD实现医用X光图像的低成本高清晰显示。通过采集并缓存CCD输出的隔行扫描的原始图像,通过图像的相关算法实现去噪处理,增加图像的水平分辨率,并采用75HZ的逐行扫描的输出,得到非常清晰的X光图像。着重讨论了该原理在XILINX SPATAN3 FPGA上的具体实现。更多还原

【Abstract】 This paper gives detailed instructions about the implementation of clearly display of X-rays image based on X-rays image-intensifier-tube and common industrial CCD. By collecting the interlaced scanning CCD output, buffer and process the original image by the image noise suppression algorithms, at last output the image with non-interlaced scanning by 75HZ and increase the image resolution. The algorithms based on SPATAN3-FPGA are especially discussed in this paper.更多还原
