In certain cases, a collimator may not fully dock, which triggers a system interlock and prevents motion from the operator console. If personnel then enter the treatment room and initiate motion using the in-room control pendant, the collimator may release and fall from the housing.

Software may fail to load adapted baseline shift plan during treatment delivery when a communication error occurs.

Due to a manufacturing issue and electrical grounding of systems.

Using oncology information system that manages workflow may result in overtreatment if:Plan delivered with Particle Therapy IHE-RO TDW-II interface,With one field per fraction or last field partial treatment,Partial treatment occurs followed by treatment field interruptions with manually recorded partial treatment,Then treatment unit doesn't check meterset value so partial treatment delivered twice

Due to issues with the system's stereotactic radiosurgery (SRS) treatment cannot be guaranteed for all couch angles and system setups. n certain cases, the system may indicate the patient as correctly positioned at the isocenter, even when the isocenter is positioned outside of the indicated tolerance.

When appending a care plan that contains one or more wave medication orders, the occurrence and frequency of the appended orders may not match the intended schedule.

If the radiosurgery system triggers a proximity error message during a long gantry move (greater-than180 degrees), and a subsequent proximity error message occurs after the automatic reduction of speed, a software defect could potentially lead the collimator to collide with patient shoulders or the patient table.

Software issue with scanning equipment that can results in the filed rotation not being applied correctly.

Wrong analysis results can occur if the user creates two structures with the same name, except for one differing by a special character.

Image offsets calculated by oncology Information System software may be incorrect for Linear Accelerator (LINACs) not characterized at IEC61217 scale.

Snap rings may become partially or completed detached from the shafts within the internal mechanism. Uncontrolled rotation may occur on the left and right roll axes when the rings are removed or damaged.

This recall has been initiated due to a failure to provide an MRI Insert that is to be provided to the patient.

Software: If the user excludes voxels from the Gamma calculation that are below a dose threshold (Suppress gamma calculation), the Gamma Passing Rate (GPR) calculated for individual ROIs is not correct. The GPR calculated by VERIQA overestimates the correct GPR. The evaluation can therefore show false positive results.

MicroSTARii readers may be contributing to the nanodot dosimeter measurement inaccuracy in two possible ways. The first is related to the interaction of the reader s LED beam profile with the nanoDot dosimeter. The second is debris formation due to drawer actuation, resulting in a change of reader response that may not be detectable unless known dose QCs are being run regularly.

Elekta has identified that if the microswitch within the middle arm is incorrectly setup, there is a potential for an uncontrolled extension of iViewGT / XVI detector arms. When the detector arm is fully deployed there is no risk of uncontrolled extension.
