  • Causa
    Varian received two reports from customers with c-series linear accelerators (linac) used with varian’s barcode conical collimator verification system (bccv) and brainlab’s exactrac patient positioning system where the user was able to clear the interlock for bccv, imposed by the 4ditc, from the exactrac console. in both reported cases, the user was employing a c-series he linac with 4ditc and both exactrac and bccv. the user was authorising the exactrac to the linac 4ditc. successive signals were sent from the exactrac to the 4ditc. the first signal cleared the exactrac interlock as intended. the exactrac console requested user confirmation of the second command to authorise. the user responded affirmatively. the signal was sent to the 4ditc, and the linac interlock associated with bccv was released. in such a situation, it may be possible to irradiate the patient using a cone other than what is specified by the treatment plan because the bccv verification was not completed.
