Question
Can the myQA SRS device be used for non-coplanar treatments?
Answer
Yes, the myQA SRS device can be used for non-coplanar treatment plan verification. The myQA SRS phantom has a cylindrical shape which makes it compatible for non-coplanar arc delivery. The electronics are shielded sufficiently to even allow for 90 degree couch angles and partial arc deliveries. The myQA SRS look-up tables that are used for the correction of the angular dependency of the detector are independent of the couch position as long as the detector is in zero degree position inside the myQA SRS Phantom.
Please Note: When in phantom rotations are used, the software expects the couch angle to be 0°. Otherwise the LUTs will not be correctly applied.
