Plain-English summary

Elekta Inc is recalling the Monaco RTP System, specifically software versions 5.10 and 5.11, which are used as Radiation Treatment Planning Systems. The recall affects 1,396 units distributed worldwide.

The recall is due to a software defect that occurs when creating 3D plans using either MU or Dose weighting modes. If a user changes the number of fractions, rescales the plan, and then changes the wedge angle, the Monitor Units are scaled incorrectly. This error could result in inaccurate treatment planning.

Healthcare facilities and users of the affected software should contact Elekta Inc for further instructions on how to resolve the issue. The source text does not report any specific injuries or illnesses associated with this defect.
