Palliative radiotherapy of soft tissue tumoral masses based on diagnostic instead of planning computed tomography scans

Physics and Imaging in Radiation Oncology
Background and purpose: Radiotherapy (RT) treatment planning is based on a planning computed tomography scan (pCT), while the decision to treat is often already established on a diagnostic CT scan (dCT).
