Reason for recall

When creating 3D plans using either MU or Dose weighting modes, if the user changes the number of fractions, rescales the plan and then changes the wedge angle, the Monitor Units are scaled incorrectly.

Device recalls are issued when a component, software or design fault could cause the device to fail or give wrong readings. Many are corrections applied in the field rather than physical returns.
