Point Dosimetry in Patient-specific Quality Assurance of a Robotic Radiosurgery System Using a Scintillation Detector

Journal of Medical Physics
Purpose: Patient-specific quality assurance (QA) for CyberKnife is typically performed using micro ionization chambers and film dosimetry. However, micro ionization chambers tend to underestimate dose measurements in small radiation fields.

On the sensitivity of patient‐specific IMRT QA to MLC positioning errors

Journal of Applied Clinical Medical Physics, 2009
Accurate multileaf collimator (MLC) leaf positioning plays an essential role in the effective implementation of intensity modulated radiation therapy (IMRT). This work evaluates the sensitivity of current patient‐specific IMRT quality assurance (QA) procedures to minor MLC leaf positioning errors.

Analysis of delivery and recalculation of dose using DICOM treatment records

Radiation Medicine and Protection, 2022
Objective: A procedure has been proposed for patient-specific QA that, instead of comparing a measurement to the planned dose, compares the dose calculated by an independent system to the dose calculated by the planning system.
