The active source may have movement difficulties and become stuck during source extension or retraction. The problem may occur with the source outside of the
HDR unit's
tungsten shield.
This type of event was first seen in December 2008.
This event has occurred three times:
"a) Southwest Regional Cancer Center, Austin TX - December 2, 2008 [see EN #44697]
"b) Hershey Medical Center, Hershey PA - December 11, 2008
c) Stanford University Medical Center, Stanford, CA - December 30, 2008
In each case the problem occurred during a routine source exchange and patients were not involved. The emergency retract handle was used in each occurrence to retract the source and park it safely in the HDR unit's tungsten shield. The relationship between the source exchange and the problem is unknown.
