When Accuracy matters, Resolution matters!

myQA SRS provides the clinical resolution needed for the most advanced QA:

  • Measurement-based Patient QA is strongly encouraged e.g. by AAPM-RSS Medical Physics Practice Guideline 9.a. for SRS/SBRT.
  • However, publications have shown that “detector resolution is of main importance to avoid getting false positive [QA results].” 
    A. Bruschi et al.: Detector resolution affects the clinical significance of SBRT QA. Find link to Publication here.
  • Other commercially available detector arrays for SRS/SBRT do not provide sufficient measurement resolution.
  • myQA SRS is the new and unique solution providing film-class resolution clinically needed to avoid false QA results.
