| Popis: |
To increase geometric treatment accuracy in radiation therapy, we used a novel digitized method and original image processing. The radiographic films that are conventionally used for verifying each beam during the treatment were digitized by a Kodak digital system and then an original image enhancement was applied. For the evaluation of our technique, a clinical trial with two tests was used. The trial involved four readers doing 80 reading. The enhanced films were judged to be of higher quality than the non enhanced films (p = 0.001) and were read more accurately (por = 0.001). This automatic enhancement of digitized captured portal images can be easily integrated into the busy routine of a radiotherapy department. |
