  • Reason
    An anomaly has been found with the clinac trilogy novalis tx and unique jaw carriers. the jaw carriers function to couple the x-jaws to their respective drive screw mechanisms used for controlling field size. some jaw carriers were manufactured with the incorrect metal alloy which can potentialy cause the jaw carrier to crack. if both jaw carriers on the same x-jaw were to crack the jaw would be able to move freely in the closed direction. in this case the deviation of the jaw position will not be detected by the position readout interlock circuitry. treatment after such a failure occurs may lead to an under -dose of the intended target volume.
