Color-Coded Imaging with Adaptive Multiscale Spatial Filtering

Digital subtraction angiography has become one of the most important approaches to artery disease diagnosis and treatment. Doctors implement diagnose and treatment by subjective analysis of the DSA series, and the results are always dependent on doctors’ experience. The application of color-coded imaging technology makes it convenient to identify images and provides additional physiology information auxiliary diagnosis and treatment. Before implementing color-coded imaging technology on DSA series, we preprocess the images with several mutiscale spatial filters to remove noises and enhance vessel structures to make the results readable and clear.
