Recall Action Classification Class II
Recall Action Commencement Date 23/11/2017
Responsible Entity Emergo Asia Pacific Pty Ltd T/a Emergo Australia
Reason/Issue It has been identified that an issue found with the electron dose calculation in RayStation 3.5, RayStation 4.0, RayStation 4.5, RayStation 4.7, RayStation 5, RayStation 6, RayPlan 1 (RayStation 4.9) and RayPlan 2 (RayStation 6). When calculating electron Monte Carlo dose with a very large number of histories, the dose calculation may be wrong.
To the best of our knowledge, the issue has not caused any patient mistreatment or other incidents. However, the user must be aware of the following information to avoid incorrect dose calculations during beam modelling and treatment planning.

Electron dose calculation in RayStation uses a Monte Carlo dose engine, where a large number of particles are simulated. Each simulated particle is called a history, adding to the simulated dose. The number of histories can be adjusted for each dose calculation.
Recall Action Recall for Product Correction
Recall Action Instructions Operators should inspect their product and identify all installed units with the above software version number(s), then confirm you have read and understood this notice using the supplied Client Response Form.
Operators should not use a number of histories above 6 million for electron dose calculation and should inspect all commissioned electron beam models for any applicator calculated with greater than 6 million histories.
This issue will be resolved in the next version of RayStation, scheduled for market release in December 2017
