FDA action: Raysearch issued Field Safety Notice, Medical Device Correction #148655 RayStation version 4.5 to 2024B including some service packs via email on 1/17/25. Letter states reason for recall, health risk and action to take: For users of HU-to-mass density CT calibration curves If a user wants to evaluate a plan with respect to relative stopping power/WE range error rather than mass density errors, there are two options: Option 1. Use a HU-to-SPR CT calibration curve instead of a HU-to-mass density curve. " For evaluation of an existing case, the evaluation can be done on an anonymized and exported copy of the patient and plan. " Contact RaySearch Service if you need help with the creation of a HU-to-SPR curve from an existing HU-to-mass density curve. Option 2. Evaluate the plan using a higher (effective) mass density uncertainty that gives similar relative stopping power and WE range change as the nominal value. " The following values of Effective mass density errors that give similar result as an intended Stopping power error have been deduced from a limited set of patients: " For other values of intended Stopping power error, interpolate the approximate Effective mass density value from the table above. " The values are estimates based on a few patients and are expected to vary slightly depending on the mass densities along the beam path. " Note that the values are not symmetrical around 0. For users of HU-to-SPR CT calibration curves Be aware that the density uncertainty given in Robust evaluation, Compute perturbed dose and Robust optimization is used directly to scale stopping...

FDA reason: An issue where the combined density in a dose grid voxel partially covered by the External ROI and also partially covered by an ROI of type Bolus, Support or Fixation may be unexpected.The density in the voxel can be both under- and overestimated FDA action: RaySearch issued Field Safety Notice, Medical Device Correction #84236 via E-mail on 22 September 2021. Letter states reason for recall, health risk and action to take: " Use the automatic tool in RayStation/RayPlan to create the External ROI. " When using a Support or Fixation ROI of tissue-like material (density around 1), extend this ROI a few millimeters inside the External ROI to cover the surface voxels of the patient. " If the Support or Fixation ROI differs significantly from the adjacent body tissue, an extra help ROI with material override set to a suitable material, for example, Skin, can be created inside the External ROI. The help ROI must have a width of a few millimeters and extend along the part of the patient surface connected to the Support or Fixation ROI. The same workflow can be used for Bolus ROIs in combination with electron beams. " If the bolus/support/fixation device is part of the CT data, an alternative solution is to include its structure inside the External ROI. In this case the structure should not be defined as a Bolus, Support or Fixation ROI, but as a normal ROI, by setting the ROI type to, for example Other . When included in the External ROI, the user can choose to use the CT densities or to apply a material override to the structure. If this method is applied for a bolus, the user must make sure that only the applicable beams pass through the structure. " For protons and light ions, the user should consider using a higher...
