METHODS AND SYSTEMS FOR TASK-BASED DATA GENERATION AND WEIGHTING FOR CT SPECTRAL IMAGING |
| 摘要 |
Various methods and systems for weighting material density images based on the material imaged are disclosed. In one embodiment, a method for dual energy imaging of a material comprises generating an odd material density image, generating an even material density image, applying a first weight to the odd material density image and a second weight to the even material density image, and generating a material density image based on a combination of the weighted odd material density image and the weighted even material density image. In this way, the image quality may be improved without increasing a radiation dosage. |
