Quality Assurance01:19

Quality Assurance

167
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...

Computed Tomography01:10

Computed Tomography

4.6K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Area of Science:

  • Medical Physics
  • Radiation Oncology
  • Radiotherapy Quality Assurance

Background:

  • Helical tomotherapy requires rigorous delivery quality assurance (QA) to ensure treatment accuracy.
  • Current QA methods often involve time-consuming manual analysis using commercial software.
  • Automation of gamma analysis can enhance efficiency and consistency in QA procedures.

Purpose of the Study:

  • To develop and validate a fully automated in-house gamma analysis software.
  • To specifically address the QA of helical tomotherapy plans using the 'Cheese' phantom.
  • To compare the performance of the automated software against manual analysis by medical physicists.

Main Methods:

  • Automated region of interest selection via edge cropping and dose thresholding.
  • Image registration algorithm for aligning measured and computed dose distributions.
  • Optimization of film scaling factor to maximize gamma passing rate (3%/3 mm criteria).
  • Evaluation of software performance with introduced setup uncertainties.
  • Comparison of results from 73 tomotherapy plans analyzed by the in-house software and commercial packages.

Main Results:

  • The developed software successfully automated gamma analysis for tomotherapy delivery QA.
  • Average gamma passing rate (GPR) was 3.0% higher using the automated software compared to clinical software.
  • One plan failed QA with the automated software (GPR < 90%) despite passing manual analysis, highlighting improved sensitivity.

Conclusions:

  • Automated and standardized gamma analysis software improves clinical efficiency and analytical veracity.
  • The developed software offers a reliable tool for helical tomotherapy QA.
  • Further investigations can leverage the software's capabilities for analyzing various scaling factors and setup uncertainties.
