Device Facts

• Record ID: K133331
• Device Name: 4D INTEGRATED TREATMENT CONSOLE
• Applicant: Varian Medical Systems, Inc.
• Product Code: MUJ · Radiology
• Decision Date: Jan 27, 2014
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 892.5050
• Device Class: Class 2
• Attributes: Software as a Medical Device

Indications for Use

The 4D Integrated Treatment Console provides assistance for accurate treatment delivery for each patient by monitoring linear accelerator parameters and by preventing the radiation therapy device from commencing irradiation when any parameter is out of conformance with the treatment plan.

Device Story

4DITC retrieves treatment plans and images from Oncology Information System (OIS) and sends them to Treatment Console System (TCS). It verifies planned treatment parameters against TCS delivery parameters for accuracy. If parameters match, treatment proceeds; if out of conformance, device prevents irradiation. Post-session, it records treatment history back to OIS. Used in clinical radiation therapy settings by trained operators. Version 13 adds support for imaging-only sessions, ad hoc kV imaging, unplanned treatments, Flattening Filter Free (FFF) treatments, delta couch shifts, multiple isocenters, and stereotactic (SRS) dose limits. It removes major plan editing capabilities to ensure edits occur only in planning software or specific unplanned modes. Benefits include enhanced safety through automated parameter verification and support for advanced delivery techniques.

Clinical Evidence

No clinical data. Verification and validation testing performed on a production-equivalent device under clinically representative conditions to confirm functionality and performance against design inputs. Regression testing verified integrity of changes.

Technological Characteristics

Software-based console for radiation therapy parameter verification. Interfaces with OIS and TCS. Features include barcode/manual verification for bolus and conical collimators, support for FFF/HIM, SRS dose limits, and Unicode/National Language Support. Operates as a networked system component. No specific hardware materials or sterilization methods described as it is a software-based console.

Indications for Use

Indicated for patients undergoing radiation therapy. Assists operators in ensuring accurate treatment delivery by monitoring linear accelerator parameters and preventing irradiation if parameters deviate from the prescribed treatment plan.

Regulatory Classification

Identification

A medical charged-particle radiation therapy system is a device that produces by acceleration high energy charged particles (e.g., electrons and protons) intended for use in radiation therapy. This generic type of device may include signal analysis and display equipment, patient and equipment supports, treatment planning computer programs, component parts, and accessories.

| Predicate Device: | Varian Medical Systems, Inc., 4D Integrated Treatment<br>Console (k091132) |
| Device Description: | The 4D Integrated Treatment Console (4DITC) allows the<br>user to retrieve treatment plans and images from the<br>Oncology Information System (IS) and send the plan and<br>images to the Treatment Console System (TCS). The<br>planned treatment parameters from the OIS are verified<br>against the TCS delivery parameters for accuracy. All<br>treatment parameters on the TCS must match the treatment<br>parameters on the 4DITC before treatment can be delivered.<br>After the treatment has been completed for the session, the<br>user closes the session and treatment history is sent to the<br>OIS to be recorded. The recorded treatment history can then<br>be displayed and reviewed in the OIS. |

The 4D Integrated Treatment Console has been modified to support additional treatment tasks and import/export interfaces. The following chart shows the new features as well as two features that have been removed in version 13.

### Note the reasons for the removal of features:

- 1. Major Plan Edits: We are no longer supporting major plan edits which were User Riahts controlled outside of Unplanned Treatment Mode. This change will assure that edits to major plan parameters occur only in the Treatment Planning/Oncology Information Planning software or in the 4D Unplanned Treatment Mode.
- 2. Gantry angle acquired for treatment fields with adhoc CBCT fields: The intention of the feature was to allow the user to acquire the gantry angle on the adhoc CBCT field. The consequence was that the user could also acquire the new gantry angle for the treatment fields which is considered a major plan edit. Removing the capability to acquire the gantry angle for the treatment fields continues to allow the user to acquire the CBCT gantry angle, while honoring the Plan Edit Preferences in 4DITC Administration.

### Verification and Validation Testing

Verification testing was performed to demonstrate that the performance and functionality of the new and existing features met the design input requirements.

Regression testing was performed to verify the integrity of any changes.

Validation testing was performed on a production equivalent device, under clinically representative conditions by qualified personnel.
