冠状动脉造影电影图象数字式图象处理的临床实验研究

Clinical and Experimental Study on Coronary Cineangiography Processed by Digital Image Processing

采用数字式图象处理技术对１２１帧临床冠状动脉造影电影图象和４０帧实验性离体犬冠状动脉造影电影图象进行了图象处理。对数字式图象处理在改善冠状动脉造影图象质量中的作用、数字式图象处理是否影响冠脉造影血管测量及选择较优的图象处理功能进行了临床实验研究。结果发现：数字式图象处理能明显改善冠脉造影图象质量。

By means of digital image processing techniques,121 images of clinical coronary cineangiography and 40 images of experimental coronary cineangiography of fresh dog cardiac specimenshave been processed. In order to assess the quality improvement of digital image processing on coronary cineangiography,to select better image processing methods, and to determine whether the digital image processing effect the measurement of coronary angiograpy, a clinical and experimental study has been done. It concludes that digital image processing can remarkably improve the quality of coronary cineangiographic images, without effecting the measurement of coronary angiography.
