Plane Viewer Tool to support myQA SRS in-phantom rotation and shifts

Visualize 3D dose distribution and find the best myQA SRS setup to effectively evaluate multiple targets at once, and import arbitrary dose planes for myQA SRS.  
It is now possible to efficiently measure and evaluate multiple targets at any rotational angle with myQA SRS.

About myQA SRS plane viewer

Detailed instructions for the use of the Plane Viewer Tool, including necessary pre-requisites, so you don’t need to be an expert to use it.

  • Jelle Smeulders from UZ Brussel presented his findings at ESTRO 2022 for myQA SRS validation and film comparison for SRS/SBRT patient-specific QA: myQA SRS is nearly equivalent to film measurements and maximizes accuracy for small fields.

Experience with myQA SRS in the USA

“Patient-specific SRS and SBRT QA results look great using the myQA SRS even for very tight parameters of 2mm/2%. The digital detector QA workflow with myQA SRS is 106 times faster and easier compared to using film. The film-equivalent resolution for our QA measurements is the basis for better and more meaningful SRS patient plan verification with a high sensitivity and specificity to detect real dosimetric issues.”

Experience with myQA SRS in the UK

“The high resolution of myQA SRS detector gives us high confidence in our stereotactic treatments, including SBRT spine, prostates and liver. We have achieved excellent Gamma Analysis QA results at 2 % and 2mm. The detector matched the performance of our ionisation chambers and compared excellently to film. The detector, phantom and software package is easy to use and integrates seamlessly into our myQA Platform. Obtaining instant high-resolution results without the need for lengthy film measurements is a big advantage.”

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.
  • Automated gantry angle correction with the wireless Gantry Sensor+.
