The Value of Radiation Therapists in Online Adaptive Radiotherapy [PDF]

Journal of Medical Radiation Sciences
Value‐based health care (VBHC) is an evolving paradigm in healthcare that prioritises patient outcomes relative to the costs incurred. VBHC emphasises efficiency, quality, and patient satisfaction as metrics and determinants of healthcare.

Investigation of changes in planning target volume and regression probability of rectal boost using in-silico cone-beam computed tomography-guided online-adaptive radiotherapy [PDF]

Physics and Imaging in Radiation Oncology
Background and purpose: Radiotherapy boost to the primary tumour may enable organ preservation in locally advanced rectal cancer (LARC). This study evaluated cone-beam computed tomography (CBCT)-guided online-adaptive radiotherapy (ART) to reduce rectal ...

CBCT-based online adaptive radiotherapy of the bladder - geometrical and dosimetrical considerations compared to conventional IGRT. [PDF]

Radiat Oncol
Bladder cancer radiotherapy presents unique challenges due to the dynamic anatomy of the bladder and the surrounding organs. Conventional image-guided radiotherapy (IGRT) relies on fixed treatment margins and daily couch corrections, which can result in ...

Reduction of the planning target volume with daily online adaptive radiotherapy in bladder cancer. [PDF]

Strahlenther Onkol
External radiation therapy for bladder cancer requires large planning target volumes (PTVs) due to the daily anatomy of the bladder. Online adaptive radiotherapy (oART) can reduce the PTV by considering daily anatomical changes.
