Quality Assurance01:19

Quality Assurance

Quality assurance is the overarching term used to describe the activities employed to ensure the proper performance of a system. These activities can be classified into three categories: quality control, quality assessment, and internal corrective measures. Typically, these activities work cyclically: quality control is performed before and during the analysis, while quality assessment occurs during and after the investigation. Internal corrective measures are implemented based on the findings...

Quality Control

Quality control is one of the three cyclical quality assurance activities that help keep a system under statistical control. Typical quality control activities include creating quality control charts, conducting proficiency testing, and documenting and archiving results.
Quality control helps track data, visualize trends, and identify variations, making it easier to detect deviations that may affect the accuracy of an analysis. One way to do this is by generating a quality control chart, which...

Area of Science:

  • Medical Physics
  • Radiation Oncology
  • Radiotherapy Quality Assurance

Background:

  • A commercial treatment planning system (TPS) was recently installed at Sao Paulo University School of Medicine Clinicas Hospital-Brazil.
  • Implementing a robust quality assurance (QA) program is crucial for ensuring the accuracy and reliability of TPS in clinical practice.
  • Existing guidelines from the International Atomic Energy Agency (IAEA) TRS 430 and the American Association of Physicists in Medicine (AAPM) Task Group 53 provide a framework for TPS QA.

Purpose of the Study:

  • To establish and perform necessary quality assurance tests for a newly installed commercial TPS.
  • To validate the TPS performance against manufacturer specifications and established clinical standards.
  • To streamline the QA process by identifying the most critical tests for photon beams from linear accelerators.

Main Methods:

  • Tests were conducted in accordance with IAEA TRS 430 and AAPM TG 53, encompassing acceptance, commissioning (dosimetric and non-dosimetric), periodic QA, and patient-specific QA.
  • Dosimetric tests utilized a Farmer ionization chamber in a phantom, measuring absolute dose for various field geometries and build-up region behavior.
  • Comparison of manually calculated monitor units (MU) with TPS-generated MU was performed using confidence limits for analysis.

Main Results:

  • Acceptance tests confirmed that the TPS hardware, network integration, data transfer, and software parameters met manufacturer specifications.
  • Commissioning dosimetric tests demonstrated acceptable performance for simple and complex field geometries, including off-axis hard wedges and build-up regions.
  • Analysis indicated that focusing on crucial tests like oblique incidence, shaped fields, hard wedges, and build-up region behavior can reduce overall workload.

Conclusions:

  • The implemented QA program successfully validated the commercial TPS for clinical use.
  • The study identified key dosimetric tests that are most critical for ensuring accurate radiation delivery.
  • Staff experience gained during TPS QA implementation is valuable for training and future quality management.
