Deformable registration of abdominal kilovoltage treatment planning CT and tomotherapy daily megavoltage CT for treatment adaptation

The authors evaluated the procedure on multiple image datasets from prostate cancer patients and gynecological cancer patients. Compared to rigid alignment, the proposed method improves volume matching by over 60% for the critical organs and reduces the prostate landmark registration errors by 50%.

CyberKnife radiosurgery in the treatment of complex skull base tumors: analysis of treatment planning parameters

Data indicate that CyberKnife treatment plans with excellent homogeneity, conformity and percent target coverage can be obtained for complex skull base tumors.

A technique for stereotactic radiosurgery treatment planning with helical tomotherapy.

A robust and efficient planning technique was identified to produce plans of radiosurgical quality using the TomoTherapy treatment planning system. Dose calculation did not exceed a few hours and resulting delivery times were less than 1 hour, which allows the process to fit into a single day radiosurgery workflow. Plan conformity compared favorably with published results for gamma knife radiosurgery. In addition, plan homogeneity was similar to linac-based approaches.
