Recall Insight
This recall's affected scope, documented in the Recall Profile below, stays within a single-region or limited-distribution footprint. Distribution scope (see Distribution below) directly affects the consumer exposure window and determines whether a recall remains regional or escalates into a nationwide advisory.
Within the same product category the archive holds 6 closely related recalls, 6 from FDA Devices - clustering in a narrow category often points to a systemic quality-control or supplier issue rather than a one-off defect. Always verify the recall number against the official agency record before acting.

Product description
RayStation software version 4.0.3.4 RayStation is a software system designed for treatment planning and analysis of radiation therapy.
Reason for recall
This notice concerns a problem with the computation of ROI voxel volumes for cases where the CT has variable slice spacing. The dose grid volumetric representation of an ROI can be wrong. This affects all dose-volume properties for such ROIs, including DVH, dose statistics, clinical goals and constraints or objective functions. Furthermore, if material override ROIs are used, or if the external is not represented by contours, the bug can trigger an error in the 3D dose distribution.
