Overview of recall records associated with RAYSEARCH LABORATORIES AB, including dates, categories and classifications where available.
Classification mix: Class II: 90.
Software error was identified in the Pencil Beam Scanning (PBS) and Line Scanning (LS) dose calculation algorithms that could result in a local underestimation of expected dose.
Due to physical limitations of the treatment machine, the maximum field opening for Siemens Virtual Wedge fields recommended by the LINAC vendor will be more restricted in the wedged…
There is a potential for erroneous propagation of the current tabletop positions when applying pitch or roll correction. Even though pitch and roll correction is never propagated, non-zero…

Three issues found: i) The Map ROI options in the ROI list in the Structure Definition module may generate unintended ROI geometries ii) Elekta guard leaf behavior. There is an…
Editing a static arc beam may unexpectedly set the MU of the beam to its initial default value of 200 MU. If the bug is triggered, the dose is invalidated and needs to be recalculated…
When calculating electron Monte Carlo dose with a very large number of histories, the dose calculation may be wrong
Isocenter shifts when using dose tracking in RayStation 3.5, RayStation 4.0, RayStation 4.5, RayStation 4.7, RayStation 5, RayStation 6, RayStation 7 and RayStation 8A. In these versions,…
Robust optimization for plans using beam set + background dose is not supported in RayStation 4.5, RayStation 4.7, RayStation 5, RayStation 6 and RayStation 7.
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…
If the beam model has a highly asymmetric primary source, it is not correctly taken into account in the calculation of DMLC fields when the collimator is rotated. This could lead to…
The dose calculation accuracy may in some situations be less than expected. The user must be aware in order to avoid incorrect dose calculations during treatment planning.
Software issue with Center Beam in Field functionality. Issue can result in incorrect treatment volume delivered to patient.
This page summarizes recall records in which the official source identifies RAYSEARCH LABORATORIES AB as the recalling firm or manufacturer. The number of records should not be treated as a safety rating or a measure of company size, because recall counts depend on product mix, reporting periods and how government records are organized.
Compare the dates, categories and classifications together rather than relying on the total alone. Open an individual record for the recalled product, reason, distribution details and current instructions available from the source.
