简要总结
This study investigates the feasibility of imaging and treatment on a novel 1.5 T MR-Linac radiotherapy hybrid device.
详细描述
Novel hybrid devices combine magnetic resonance imaging (MRI) and a linear accelerator in a single device. The superior soft tissue contrast compared with cone-beam computed tomography based treatment and the possibility for daily plan adaptation promise a higher precision of treatment, better target volume coverage and normal tissue sparing. In a first step the present study will test the feasibility of imaging and treatment on the 1.5 T MR-Linac.
