Frequently Asked Questions
How does MatriXX Resolution compared 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 detector?
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 the 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, etc.). 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. For more details, please contact the IBA Dosimetry representative in your region.
I have a gantry holder for MatriXX Evolution. Can I use this holder for MatriXX Resolution?
Your MatriXX Evolution holder can easily be upgraded for compatibility with MatriXX Resolution.
