Patient motion can cause misalignment of the tumour and toxicities to the healthy lung tissue
during lung stereotactic body radiation therapy (SBRT). Any deviations from the reference …

Beams-eye-view imaging applications such as real-time soft-tissue motion estimation are
hindered by the inherently low image contrast of electronic portal imaging devices (EPID) …

Objective. Using MV images for real-time image guided radiation therapy (IGRT) is ideal as it
does not require additional imaging equipment, adds no additional imaging dose and …

Objective. Megavoltage cone-beam computed tomography (MV-CBCT) imaging offers
several advantages including reduced metal artifacts and accurate electron density mapping …

Purpose To develop fastCAT, a fast cone‐beam computed tomography (CBCT) simulator.
fastCAT uses pre‐calculated Monte Carlo (MC) CBCT phantom‐specific scatter and detector …

Megavoltage (MV) X‐ray detectors used in cancer treatment either suffer from low sensitivity
(scintillators) or prohibitively high cost (direct conversion). Here solution‐processed direct …

The performances of the pixelated CsI (Tl) scintillation screens based on oxidized silicon
micro-pore array templates with different CsI (Tl) micro-column shapes and array structures …

Purpose A novel Megavoltage (MV) multilayer imager (MLI) design featuring higher
detective quantum efficiency and lower noise than current conventional MV imagers in …

Purpose Single-energy computed tomography (CT) often suffers from poor contrast yet
remains critical for effective radiotherapy treatment. Modern therapy systems are often …

We have developed a Monte Carlo computational model of a clinically employed electronic
portal imaging device (EPID), and demonstrated the impact of phosphor optical properties …
