DEVICE FOR GENERATING DIFFERENTIALLY ENHANCED IMAGES |
| 摘要 |
<p>"Device for generating differentially enhanced images". The device for generating differentially enhanced images produces differential images having a high signal-to-noise ratio in that the differential image is determined by formation of the difference between two (different) weighted sums of successive images. This technique is important notably for vascular examinations using X-rays.</p> |
