Cone‐beam CT (CBCT) is the most commonly used onboard imaging technique for target
localization in radiation therapy. Conventional 3D CBCT acquires x‐ray cone‐beam …

Proton beam therapy (PBT) is often more attractive for its high gradient dose distributions
than other treatment modalities with external photon beams. However, in thoracic lesions …

Abstract Introduction In Selective Internal Radiation Therapy (SIRT), 90 Y is administered to
primary/secondary hepatic lesions. An accurate pre-treatment planning using 99m Tc-MAA …

Background and purpose Spirometry induced deep-inspiration-breath-hold (DIBH) reduces
intrafractional motion during upper abdominal stereotactic body radiotherapy (SBRT). The …

Purpose To evaluate the accuracy/agreement of a three-camera Catalyst Surface Guided
Radiation Therapy (SGRT) system on a closed-gantry Halcyon for Free-Breathing (FB) and …

Purpose In lung SABR, interplay between target motion and dynamically changing beam
parameters can affect the target coverage. To identify the potential need for motion …

Simple Summary Surface tracking based on optical cameras is often used to reduce the
imaging dose while maintaining precision during stereotactic ablative body radiotherapy. A …

Purpose Surface-guided radiation therapy is an image-guided method using optical surface
imaging that has recently been adopted for patient setup and motion monitoring during …

Abstract Purpose: To develop SurVolT, a conversion tool able to apply volumetric changes
to DICOM Computed Tomography (CT) data using daily surface (obj) data acquired with …

Purpose To investigate a novel optical markerless respiratory sensor for surface guided spot
scanning proton therapy and to measure its main technical characteristics. Methods The …
