Plain-English summary

RayStation and RayPlan are radiation therapy planning software systems used by healthcare facilities to plan cancer treatment. Affected versions range from RayStation 4.0 through version 12.0 and RayPlan versions 1, 2, and 7-11B. These versions contain an error in calculating the source-to-skin distance (SSD)—the distance between the radiation source and the patient's skin or body surface.

The incorrect SSD calculation may result in dose errors in radiation treatment plans. This means the software may specify an inaccurate radiation dose for patients' therapy.

A total of 653 units have been recalled, with 149 units distributed in the United States and 504 units distributed internationally. The US distribution covered all 50 states and Washington, D.C. The FDA classified this as a Class II medical device recall.
