Varian High Energy Clinacs, High Energy Accelerator, Radiation Treatment System, Model Numbers: H14, H27, H29, HCX. Product Usage: The Varian High Energy Accelerator is intended to provide stereotactic radiosurgery and precision radiotherapy for lesions, tumors and conditions anywhere in the body when radiation treatment is indicated.

Class I - Dangerous

Under certain conditions, photon beams in High Energy Clinacs may experience a gradual change in beam symmetry, potentially reaching an asymmetry of up to about 7% before interlock occurs. At maximum asymmetry, this may result in no more than about 3.5% dose deviation from expected at any point in the beam, and may result in minor injury to the patient or slightly decreased local disease control.

Varian brand RPM Respiratory Gating System, RPM Gating v1.7.5 with 3D Option, Model Number: HS2 Product Usage: The RPM device is to be used to characterize the patients respiratory motion information to synchronize their operation with the respiratory motion.

Class I - Dangerous

Varian has identified an anomaly with the RPM Respiratory Gating System version I.7.5 with 3D Option. While operating with the 6-dot marker block, this version of RPM Gating may produce an inverted respiratory waveform in amplitude and phase-gating sessions.

Varian brand ARIA Radiation Oncology, ARIA Oncology Information System Radiation Oncology, Import Export Application, Model Number: HIT, Affected Versions: ARIA version 11.0 below 11.0.55, Build 11.0.28 and 11.0.34, Reference/FSCA Identifier: CP-09798; Product is manufactured and distributed by Varian Medical Systems Inc., Palo Alto, CA

Class I - Dangerous

Varian Medical Systems has identified an anomaly with the ARIA Oncology Information System Radiation Oncology [ARIA RO] DICOM import/export functionality where a 360 degree arc field may convert to static field during DICOM export or import.

Varian brand Eclipse Treatment Planning System, Model Number: H48; Eclipse 8.9 and 10.0 Reference/FSCA Identifier: CP-08922; Product is manufactured and distributed by Varian Medical Systems Inc., Palo Alto, CA The Eclipse Treatment Planning System (Eclipse TPS) is used to plan radiotherapy treatments for patients with malignant or benign diseases. Eclipse TPS is used to plan external beam irradiation with photon, electron and proton beams, as well as for internal irradiation (brachytherapy) treatments. In addition, the Eclipse Proton Eye algorithim is specifically indicated for planning proton treatment of neoplasms of the eyes.

Class I - Dangerous

Varian has identified an anomaly with the Eclipse Treatment Planning where an outdated assigned Hounsfield Unit [HU] value can be used for dose calculation when the clock on the Eclipse Client Workstation is not synchronized with the Database/System Server. Treatment of the patient using these values can therefore lead to under or over-dose.

Varian brand Clinac, Trilogy, Novalis Tx, Unique, linear accelerators; Model Number: H14, H18, H29, Reference/FSCA Identifier: CP-08881; Product is manufactured and distributed by Varian Medical Systems Inc., Palo Alto, CA. 1) The Varian Low Energy Linear Accelerator is indicated for precision radiotherapy for lesions, tumors and conditions anywhere in the body when radiation treatment i is indicated. (2) The Varian High Energy Linear Accelerator is indicated for stereotactic radiosurgery and precision radiotherapy for lesions, tumors and conditions anywhere in the body when radiation treatment is indicated.

Class I - Dangerous

Some X-jaw (lower collimator jaw) carriers were made using the incorrect metal alloy, which can cause the jaw carrier to crack. If both carriers on the same X-jaw crack, the jaw would be able to move freely in the closed direction. The position readout interlock circuitry will not detect this jaw position deviation. This may lead to treatment with an under-dose of the intended target volume.

Varian brand Varian ARIA Oncology Information System, Import Export application, v 11.0; Reference/FSCA Identifier: CP-08847; Model Number: HIT; Product is manufactured and distributed by Varian Medical Systems Inc., Palo Alto, CA The ARIA Radiation Oncology product is a treatment plan and image management application. It enables the authorized user to enter, access, modify, store and archive treatment plan and image data from diagnostic studies, treatment planning, simulation, plan verification and treatment. ARIA Radiation Oncology also stores the treatment histories including dose delivered to defined sites and provides tools to verify performed treatments. ARIA also includes optional tools to manage the oncology department's clinical and business information.

Class I - Dangerous

A software anomaly has been identified with the Import Export Application version 11.0 where MLC leaf positions for plans using BrainLab m3 and mMLC are incorrectly imported.

Varian brand Varian Eclipse Treatment Planning System for radiotherapy; Model Number: H48; Product is manufactured and distributed by Varian Medical Systems Inc., Palo Alto, CA The Eclipse Treatment Planning System (Eclipse TPS) is used to plan radiotherapy treatments for patients with malignant or benign diseases. Eclipse TPS is used to plan external beam irradiation with photon, electron and proton beams, as well as for internal irradiation (brachytherapy) treatments. In addition, the Eclipse Proton Eye algorithm is specifically indicated for planning proton treatment of neoplasms of the eye.

Class I - Dangerous

Varian has identified an anomaly with the Eclipse Treatment Planning (for radiotherapy treatments) where changing the prescription in a calculated VMAT or RapidArc plan may lead to Monitor Units which do not reflect the new prescription. If the dose prescription of a VMAT or RapidArc plan is changed after the initial Dose Volume Optimization, the Monitor Units and dose distribution may not reflect
