Clinical implementation of patient-specific quality assurance for synthetic computed tomography [PDF]

Physics and Imaging in Radiation Oncology
Background and purpose: In a magnetic resonance (MR) only planning workflow, MR image is the sole dataset acquired. In order to calculate the dose deposition, a synthetic CT (sCT) is generated to substitute the planning computed tomography (CT).

Reduction of patient specific quality assurance through plan complexity metrics for VMAT plans with an open-source TPS script [PDF]

Zeitschrift für Medizinische Physik, 2023
Purpose: Volumetric modulated arc therapy (VMAT) is a widespread technique for the delivery of normo-fractionated radiation therapy (NFRT) and stereotactic body radiation therapy (SBRT).

Patient-specific quality assurance strategies for synthetic computed tomography in magnetic resonance-only radiotherapy of the abdomen [PDF]

Physics and Imaging in Radiation Oncology, 2023
Background and purpose: The superior tissue contrast of magnetic resonance (MR) compared to computed tomography (CT) led to an increasing interest towards MR-only radiotherapy.

Validation of SRS MapCHECK for CyberKnife patient-specific quality assurance: challenges with small cone sizes [PDF]

Frontiers in Oncology
PurposeThe CyberKnife system, designed for stereotactic radiosurgery (SRS) and stereotactic body radiotherapy (SBRT), considers SRS MapCHECK an effective tool for patient-specific QA (PSQA).

Patient-specific quality assurance at the Heidelberg Ion Beam Therapy Center: 10 years experience in treatment plan verification. [PDF]

Med Phys
Abstract Background To ensure accurate, safe, and reproducible patient treatments, it is essential to have precise knowledge and a solid understanding of patient‐specific quality assurance (PSQA). For many years, the delivery of doses to all patients has been verified using dosimetric measurements.

Residual range-based quenching correction for Gafchromic EBT3 film in proton therapy patient-specific QA. [PDF]

J Appl Clin Med Phys
Abstract Background Gafchromic EBT3 film is a widely used dosimeter in radiotherapy due to its high spatial resolution and near tissue equivalence. However, its application in proton therapy is limited by the linear energy transfer (LET) quenching effect, particularly in the Bragg peak region.

Machine learning and lean six sigma for targeted patient-specific quality assurance of volumetric modulated arc therapy plans [PDF]

Physics and Imaging in Radiation Oncology
Background and purpose: Radiotherapy plans with excessive complexity exhibit higher uncertainties and worse patient-specific quality assurance (PSQA) results, while the workload of measurement-based PSQA can impact the efficiency of the radiotherapy ...

A pathway away from measurement-based patient-specific QA: A review of contemporary quality assurance for external-beam radiotherapy sub-systems. [PDF]

J Appl Clin Med Phys
Abstract Background Prior to the development of the IMRT and VMAT treatment techniques the quality assurance (QA) paradigm was one of routine linac QA supplemented by plan specific independent Monitor Unit checks and manual checks of data transfer.
