The interest of using combined MR and CT information for radiotherapy planning is well documented. However, many planning workstations do not allow to use MR images, nor import predefined contours. This paper presents a new simple approach for transferring segmentation results from MRI to a CT image that will be used for radiotherapy planning, using the same original CT format. CT and MRI image...

Radiotherapy is an important treatment modality for 40-50% of children with cancer. There is concern about late effects, particularly the neuropsychological effects of CNS irradiation, and orthopaedic effects. It is important to administer the highest standard of radiotherapy, incorporating departmental quality assurance. Meticulous planning is essential to achieve local tumour control with the...

The work described here forms part of a programme of research into the application of direct volume rendering methods to the visualization of radiation therapy plans. The full programme covers a number of related topics, including the investigation of fast parallel algorithms for interactive rendering,1,2 the design of special protocols for communication between low-cost workstations and a para...
