Other Recalls by RAYSEARCH LABORATORIES AB

• Class II: Risk 11/28/2025
  Potential for the invalidation for calculated radiation dose does not work as intended for certain Regions of Interest (ROIs). This issue occurs for some ROI(s) which have no contours and either have a material override defined, or are of type Bolus, Fixation, or Support. In these cases, adding geometry to the ROI, subsequently modifying geometry, or removing the material override does not invalidate dose as intended.
