Deformable image registration (DIR) is a versatile tool used in many applications in
radiotherapy (RT). DIR algorithms have been implemented in many commercial treatment …

Purpose This work evaluates an online adaptive (OA) workflow for head-and-neck (H&N)
intensity-modulated proton therapy (IMPT) and compares it with full offline replanning (FOR) …

Objective. To evaluate the impact of setup uncertainty reduction (SUR) and adaptation to
geometrical changes (AGC) on normal tissue complication probability (NTCP) when using …

Purpose To demonstrate the suitability of optically stimulated luminescence detectors
(OSLDs) for accurate simultaneous measurement of the absolute point dose and dose …

Objective. To experimentally validate two online adaptive proton therapy (APT) workflows
using Gafchromic EBT3 films and optically stimulated luminescent dosimeters (OSLDs) in an …

Objective. This study describes geometry-based and intensity-based tools for quality
assurance (QA) of automatically generated structures for online adaptive radiotherapy, and …

Objective: Image-guided and adaptive proton therapy rely on daily CBCT or CT imaging,
which increases radiation dose and radiation-induced cancer risk. Online adaptation …

Computed tomography (CT), known for its exceptionally high accuracy, is associated with a
substantial dose of ionizing radiation. Low-dose protocols have been devised to address …

Purpose The trend towards lower radiation doses and advances in computed tomography
(CT) reconstruction may impair the operation of pretrained segmentation models, giving rise …

Abstract The Atomic Energy Council conducted routine inspections on 42 facilities with
Computed Tomography (CT) scanners in Uganda to verify the compliance of their CTDIvol …
