METHOD AND APPARATUS FOR GENERATING WELL-REGISTERED SUBTRACTION IMAGES FOR DIGITAL SUBTRACTION ANGIOGRAPHY |
摘要 |
Contrast and mask images acquired for digital subtraction angiography are processed using an edge detection algorithm to produce edge images. Advantageously, a deterministic sign change algorithm is used to identify the mask edge image which is best registered with the contrast edge image. |
