Method and apparatus for administering low dose CT scans |
摘要 |
The present invention is directed to a method and apparatus for administering computed tomography (CT) imaging scans with reduced radiation dosage. The present invention includes an algorithm that allows for reduction of the sampling rate and tube current to acquire a first set of angular views. A second set of angular views is then created using interpolation from the first set of angular views. The sets of angular views are then combined to form a final set of angular views that are used to create an aliasing-free image of the scan subject. The present invention is particularly applicable for scanning centralized small objects such as the heart or the head and also is particularly useful in acquiring imaging data of pediatric patients.
