Recall Number: Z-2383-2012

Event ID: 63033

Reason for Recall:

Some X-jaw (lower collimator jaw) carriers were made using the incorrect metal alloy, which can cause the jaw carrier to crack. If both carriers on the same X-jaw crack, the jaw would be able to move freely in the closed direction. The position readout interlock circuitry will not detect this jaw position deviation. This may lead to treatment with an under-dose of the intended target volume.
