A dosimetry system composed by Gafchromic™ EBT films and a flatbed document scanner
is a valuable tool for patient-specific quality assurance (QA) of complex external beam …

Purpose kV radiotherapy treatment calculations are based on flat, homogenous, full-scatter
reference conditions. However, clinical treatments often include surface irregularities and …

Dose falls-off faster than the inverse square law (ISL) for orthovoltage beams with closed-
ended applicators. This work investigates the discrepancy for 30 cm FSD applicators. When …

The Xstrahl 300 orthovoltage unit is designed to deliver kilovoltage radiation therapy using
the appositional technique. However, it is not equipped with some typical linear accelerator …

Purpose: We subjected scanning electron microscopic (SEM) images of the active layer of
EBT3 film to texture analysis to determine the dose-response curve. Methods: Uncoated …

PurposeThis study aimed to examine the dosimetric properties of Gafchromic® EBT3 film
and intensity-modulated radiation therapy quality assurance (IMRT QA). Materials and …

Purpose A novel radiochromic PRESAGE sheet (Heuris Inc.) with 3 mm thickness has been
developed as a measurement tool for 2D dosimetry. Its inherent ability to conform to irregular …

Background: It is essential for the physicist to quantify the dose of the radiation prior and
during cancer treatment to ensure proper execution of the treatment plan. The most common …

In vivo dosimetry is a powerful tool to verify dose delivery accuracy. By placing a radiation
detector at a point of interest, we can validate that the expected dose is delivered to the …

Real-time dosimetry is crucial for patient-specific quality assurance in radiotherapy facilities
across Europe, and the same demand extends to advanced countries like Malaysia. Our …
