Varian brand 4D Integrated Treatment Console (4DITC) v10.2.3, Reference/FSCA Identifier: CP-06873, Model Number: H51, distributed by and manufactured by: Varian Medical Systems Inc., Palo Alto, CA The 4D Integrated Treatment Console [4DITC] is designed to interface to the Varian Clinac Treatment Control System [TCS] for the purpose of providing verification of treatment parameters, imaging and providing a record of treatment. The general function of the 4D Integrated Treatment Console is to allow treatment plans and images to be retrieved from the Oncology Information System [OIS] and sent to the TCS, planned treatment plan parameters to be verified against the TCS delivery parameters for accuracy and treatment history to be recorded in the OIS for use and display. The Barcode Conical Collimator Verification [BCCV] device assists operators of radiation therapy devices by preventing irradiation until the conical collimator required by the treatment plan is in place.

When multiple conical collimator treatment plans are scheduled to be treated in a session, the Plan Label should be displayed on the BCCV dialog box should match the Plan Label on the 4DITC. However, the name of the plan is not being updated correctly.

The firm, VARIAN Medical Systems, sent an "URGENT MEDICAL DEVICE CORRECTION-URGENT FIELD SAFETY NOTICE" dated December 12, 2011, to all affected customers. The notice described the product, problem and user corrective action steps. The customers were provided to do the following: Do not use BCCV as a primary reference for identifying the correct plan to be treated; use caution when selecting an isocenter in a positioning system that is not interfaced to the 4DITC; any discrepancies in planned versus actual parameters should be brought to the attention of the medical physicist for investigation before treatment begins, and one workaround is to schedule one plan per session.
