Recall Number: Z-2554-2018

REASON
The firm has learned that some RayStation/RayPlan users have commissioned machines with erroneous Beam profile correction parameters. These parameters affect the dose calculated in corners of large or off-axis fields. This effect cannot be seen in the Beam Commissioning module and dose in large or off-axis fields needs to be validated using the Beam 3D Modeling module in RayPhysics/RayPlan Physics. The user must be aware to avoid incorrect dose calculations during treatment planning.
