RaySearch recalls specific versions of RayStation treatment planning software due to a bug that may set beam dose to default values, requiring recalibration before treatment approval.
Editing a static arc beam may unexpectedly set the MU of the beam to its initial default value of 200 MU. If the bug is triggered, the dose is invalidated and needs to be recalculated before the plan can be approved or exported.
RaySearch Laboratories is recalling specific versions of their RayStation software treatment planning system. A bug can cause the software to reset dose calculations to default values, meaning treatments may be unsafe if not corrected before approval.
Editing a static arc beam in the software can unexpectedly reset the beam's dose calculation to a default value of 200 MU. This invalidates the dose calculation, requiring a new calculation before treatment plans can be approved or exported. If not corrected, treatments could be unsafe.
Clinically trained radiation therapy staff using RaySearch RayStation software versions 4.0 through 9.0 are most at risk. Affected users must ensure dose calculations are recalculated after any edit to the arc beam.
Check your RayStation software version numbers listed in the recall notice: 4.0, 4.5, 4.7, 4.9, 5.0, 6.0, 6.1, 6.2, 6.3, 7.0, 8.0, 8.1, or 9.0. The software is used for radiation therapy treatment planning by trained medical staff.
Verify your RayStation software version matches the recalled versions listed in the notice.
