Multiscale registration of planning CT and daily cone beam CT images for adaptive radiation therapy.
Adaptive radiation therapy (ART) is the incorporation of daily images in the radiotherapy treatment process so that the treatment plan can be evaluated and modified to maximize the amount of radiation dose to the tumor while minimizing the amount of radiation delivered to healthy tissue. Registration of planning images with daily images is thus an important component of ART. In this article, th...
متن کاملScatter correction for cone-beam CT in radiation therapy.
Cone-beam CT (CBCT) is being increasingly used in modern radiation therapy for patient setup and adaptive replanning. However, due to the large volume of x-ray illumination, scatter becomes a rather serious problem and is considered as one of the fundamental limitations of CBCT image quality. Many scatter correction algorithms have been proposed in literature, while a standard practical solutio...
متن کاملInter-fraction deformable registration of CT and Cone Beam CT images for adaptive radiotherapy
Recent advances in intensity modulated radiotherapy (IMRT) have allowed accurate and fast delivery of treatment dose in the patient. Daily changes in patient geometry need to be accounted for to take full advantage of the increased accuracy of the delivered dose. On-site imaging using cone beam CT and registration of the acquired image with the algorithm presented here provides tools for effici...

متن کاملRespiratory correlated cone beam CT.
A cone beam computed tomography (CBCT) scanner integrated with a linear accelerator is a powerful tool for image guided radiotherapy. Respiratory motion, however, induces artifacts in CBCT, while the respiratory correlated procedures, developed to reduce motion artifacts in axial and helical CT are not suitable for such CBCT scanners. We have developed an alternative respiratory correlated proc...
