Experience with MatriXX Resolution
"We tested the new MatriXX Resolution detector in our department: compared to the previous version, the detector has a great spatial resolution combined with the excellent dosimetric response of the IBA ionization chambers, which ensure precision and reproducibility at all dose, dose rate and x-ray energy conditions of clinical use. Inserted in the miniPhantom R and connected to the myQA Patients software, thanks to the new features that integrate in a simple and user-friendly way the correction for the angular response of the detector and the combination of measurements of large fields, the system allows quick and reliable pretreatment checks of IMRT and VMAT plans, with fields from small to very large size. The system therefore lends itself to providing solutions for any type of Linac and of clinical application. The high resolution that the narrow ionization chamber spacing offers is a clear advantage for clinical VMAT patient QA validation accuracy.”

Frequently Asked Questions
How was the MatriXX Resolution validated for clinical use?
In addition to intensive validation and physics testing, the MatriXX Resolution was tested by clinical users and beta customers. Please watch Medical Physicist Luca Bindoni's presentation (above) about his experience.
How does MatriXX Resolution compare to MatriXX Evolution?
Compared to MatriXX Evolution, MatriXX Resolution has 50% more measurement points, better resolution, and is completely wireless. Additionally, MatriXX Resolution is designed to be used with the full clinical range of FF/FFF energies and dose rates.
How fast is the setup for Patient QA measurements?
The highly efficient setup takes about one to two minutes, enabled through easy handling of the devices and the complete cable-free design. No plugging of power cords, no data cables needed. Please view the workflow video, above.
What is the field size of the detector array?
Field size of the MatriXX Resolution detector array is 25.3 x 25.3 cm2, and advanced software features allow measurements of fields even longer than 40 cm.
How do you handle the gantry angle dependency of the detectors?
Angular dependency is corrected via usage of the wireless Gantry Sensor+. The sensor attaches to the Linac gantry and, in real time, sends information to the MatriXX Resolution system. Information about the detector dose measurement and the gantry angle is in myQA software, combined and corrected depending on the position the radiation is coming from.
How can I validate field sizes larger than the detector active area?
The "combine fields" functionality of the myQA software supports easy and efficient QA for fields larger than the detector active area, up to very large fields (>40 cm).
Can I use MatriXX Resolution for Machine QA checks?
MatriXX Resolution with the myQA Machines software enables advanced Linac Machine QA, e.g. periodic checks (weekly, monthly…). TG 142 and different customized protocols are supported. Tests include constancy checks of profiles (inline/crossline/diagonals), energy, dose output, and wedge factor. The solution enables measuring all tests with a single beam. For energy constancy verification, optional Energy Verification Plates are available.
How can I upgrade from MatriXX Evolution to MatriXX Resolution?
Different upgrade options are available. For more details, please contact the IBA Dosimetry representative in your region.
Do I need a specific myQA software version to use MatriXX Resolution?
MatriXX Resolution can be used with myQA software version 2020-002 and newer.
