  • Causa
    An anomaly has been identified with varian treatment apploication failing to load a physical wedge filter for a treatment field delivered on a siemens mevatron linear accelerator. after a plan with wedge field is opened on varian treatment users may not observe that a wedge filter may actually be missing from one or more fields without any notification from the treatment application. the user may come to understand that the wedge filter was missing only after the treatment field had been partially or completely delivered. when the user attempts to close the patient session from the treatment application. in this situation the treatment application forces the user to unload the patient session requires user authorization and informs the user that the treatment record for the missing wedge field(s) cannot be saved to varian's oncology information system (ois). delivery of a treatment field without the planned wedge filter could result in an over dosage for that beam and potentially an unintended dose uniformity of the target treatment volume. this anomaly is intermittent and may occur infrequently. this issue could occur with a siemens elekta or ge system that has physical wedges.
