A planning approach for online adaptive proton therapy to cope with cone beam computed tomography inaccuracies [PDF]

Physics and Imaging in Radiation Oncology
Background and purpose: In online-adaptive proton therapy planning based on cone beam computed tomography (CBCT), CT number errors can pose challenges. We propose an approach for coping with CT number uncertainties by increasing range robustness settings

Synthetic computed tomography techniques for adaptive proton therapy in head and neck cancers [PDF]

Physics and Imaging in Radiation Oncology
Head and neck (HN) radiotherapy often requires corrective interventions. This study evaluated three methods for synthetic computed tomography (CT) generation for adaptive HN planning using cone-beam CT (CBCT) images.

Dosimetric comparison of autocontouring techniques for online adaptive proton therapy. [PDF]

, 2023
anatomical and daily set-up uncertainties impede high precision delivery of proton therapy. With online adaptation, the daily plan is reoptimized on an image taken shortly before the treatment, reducing these uncertainties and, hence, allowing a more ...

Late Dental Toxicities After Proton Chemoradiation for Rhabdomyosarcoma: A Pediatric Case Report [PDF]

International Journal of Particle Therapy, 2022
Purpose: Radiation therapy is an independent risk factor for adverse sequelae to the oral cavity and dentition in childhood cancer survivors. However, dental toxicities after radiation therapy often are underreported and there are minimal published data ...
