  • Cause
    It has been identified that when running monaco v 5.10 or v 5.20 and creating 3d plans using either mu or dose weighting modes, if the user changes the physician's intent rx dose and the number of fractions, and then modifies the wedge angle, the monitor unit (mu) value is scaled incorrectly. the scaling of the mu is in direct proportion to the fractional change.If the mus are not correct, the patient will be incorrectly treated. there could be a critical overdose or underdose proportional to the fractional rescale. however, prior to treatment, independent dose calculation checks and secondary mu checks should always be done. both should be standards of practice in radiation therapy clinics and will detect the problem.
  • Action
    Elekta is advising users that the issue is resolved with Monaco release 5.11.00 which is available now and with patches for versions 5.10 and 5.20. Elekta is also advising users that dose calculation checks and secondary MU checks should detect the problem, and that the problem can be avoided by forcing a Monaco recalculation (change dose calculation grid spacing and change back) when any wedge angle change is made.
