A prescription-free, radiobiology-based framework for automated VMAT planning: A feasibility study in primary prostate cancer radiotherapy. [PDF]

Med Phys
Abstract Background Current VMAT planning workflows for prostate cancer primarily depend on conventional dose–volume criteria specified at discrete dose or volume points. These point‐based objectives, however, do not necessarily lead to globally optimal, patient‐specific treatment plans.

Feasibility of 3D tracking and adaptation of VMAT based on VMAT-CT

Radiotherapy and Oncology, 2020
Local computed tomography (CT) reconstruction is achievable with portal images acquired during volumetric-modulated arc therapy (VMAT) delivery and was named as VMAT-CT. However, the application of VMAT-CT is limited because it has limited field of view and no density information.
