Treatment plan comparison of proton vs photon radiotherapy for lower-grade gliomas

Physics and Imaging in Radiation Oncology, 2021
Background and purpose: Patients with lower-grade gliomas are long-term survivors after radiotherapy and may benefit from the reduced dose to normal tissue achievable with proton therapy.

Towards interactive deep-learning for tumour segmentation in head and neck cancer radiotherapy

Physics and Imaging in Radiation Oncology, 2023
Background and purpose: With deep-learning, gross tumour volume (GTV) auto-segmentation has substantially been improved, but still substantial manual corrections are needed. With interactive deep-learning (iDL), manual corrections can be used to update a

Comparison of two dual-energy CT-based methods for proton stopping-power ratio estimation in brain cancer patients with metal implants

Acta Oncologica
Background and purpose: Accurate stopping-power ratio (SPR) estimation is crucial for proton therapy planning. In brain cancer patients with metal clips, SPR accuracy may be affected by high-density materials and imaging artefacts.

Potential benefit of scanned proton beam versus photons as adjuvant radiation therapy in breast cancer

, 2015
Purpose: To investigate the feasibility of using scanned proton beams as adjuvant radiation therapy for breast cancer. Long-term cardiopulmonary complications may worsen the quality of life and reduce the positive contribution of radiation therapy, which

Benefit of range uncertainty reduction in robust optimisation for proton therapy of brain, head-and-neck and breast cancer patients

Physics and Imaging in Radiation Oncology
Background and Purpose: The primary cause of range uncertainty in proton therapy is inaccuracy in estimating the stopping-power ratio from computed tomography.
