Description

Varian brand 4D Integrated Treatment Console (4DITC) Radiation Therapy, Interpretation of a RapidArc Treatment Plan as a 3D Conformal Arc Treatment Plan; version v8.6 or 8.8 in combination with treatment planning systems; Model Number: H51; Reference/PSCA Identifier: CP-03063; Product is manufactured and distributed by Varian Medical Systems Inc., Palo Alto, CA Product Usage: 4D Integrated treatment console is designed to assist the operator of a radiation device in providing accurate treatment set-ups for each patient by monitoring set up parameters and preventing the radiation therapy device from commencing irradiation while any parameter is out of conformance with the treatment plan.

Reason

In certain configurations, the 4DITC can interpret a RapidArc or VMAT treatment field as 3D Conformal Arc Treatment Plan. If a RapidArc or VMAT treatment field is incorrectly interpreted as Conformal Arc, the field will be delivered with a constant dose rate and gantry speed for the entire duration of the delivery, which can lead to delivered dose being different than planned.
