Event Description

Customer had a failed aqa (automatic quality assurance).Fse (field service engineer) found the fca (fixed collimator assembly) had dropped inside the covers.

Manufacturer Narrative

Customer reported the system failed laser alignment in the morning and had concerns on the failure impact to any previously treated patients.The fse removed the covers of the system and found that the fixed collimator assembly (fca) had detached.No injury occurred.Fse reattached the fca.The system was logs were reviewed.On the previous day, only two fractions were delivered to patients using the fca.After these two, mlc treatments were delivered, which require an xchange operation.The last two treatments of the day were fca head paths with fiducial tracking.These were phantom deliveries.It is most likely that the damage to the fixed collimator occurred during the xchange operation associated with changing from mlc to fixed collimator housings, so it is relatively unlikely that patients were harmed due to this mechanical failure.In conclusion, the event indicated that it was unlikely that a patient was harmed as the xchange operations that likely triggered this event occurred before qa deliveries and the problem was discovered before patients were treated the following day.
