## Indications for Use

QualiFormeD LINACWATCH / LINACVIEW is stand-alone software that analyzes radiation therapy machine (linear accelerator) performance for each fraction automatically using log files provided by the radiation therapy machine. It is to be used by trained radiation oncology personnel as a guide to alert this professional to potential machine delivery issues that can affect treatment quality and workflow. QualiFormeD LINACWATCH / LINACVIEW is not primary treatment planning or 3D dose calculation software, and cannot be used to generate radiotherapy treatment plans.

## Device Story

Standalone software analyzing linear accelerator (LINAC) performance via machine-generated log files; supports Step and Shoot, Sliding Window, and VMAT IMRT techniques. Inputs: log files from Varian/Elekta LINACs; compares against DICOM RT Plan or initial log files. Outputs: real-time alerts (via email) for non-compliant parameters (MLC leaf/carriage/jaw positions, MU delivery, gantry/collimator angles, beam statistics, reconstructed integrated fluence); generates PDF reports and composite RT Plans for TPS import. Used in clinical radiation oncology settings by physicists/therapists. Benefits: enables automated, real-time monitoring of machine delivery performance to ensure treatment quality and workflow efficiency.

## Clinical Evidence

Bench testing only. Software verification and validation conducted per IEC 62304 and FDA guidance. Results confirm compliance with predetermined specifications and performance requirements.

## Technological Characteristics

Standalone software; processes Varian and Elekta LINAC log files. Features include real-time analysis, automated batch processing, and email alert system. Supports IMRT/VMAT techniques. Software development follows IEC 62304 standards. No hardware components.

## Regulatory 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.

Dear Mr. Kroenke:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies.

# 510(k) Summary provided in accordance with 21 CFR §807.92(C)

Device Description: QualiFormeD LINACWATCH / LINACVIEW is a standalone software product analyzes logfiles generated by Varian and Elekta linear accelerators during radiation treatments. Logfile analysis can be with respect to the "prescription" DICOM radiotherapy (RT) Plan or with respect to the first logfile in a series of logfiles for each treatment and each beam. Initial logfiles that may be created for pre-treatment intensity-modulated radiation therapy (IMRT) quality assurance (QA) can be excluded from treatment session analysis.

> The preferred method of running QualiFormeD LINACWATCH / LINACVIEW is in "batch" mode. In this mode, QualiFormeD LINACWATCH / LINACVIEW automatically processes logfiles and analyzes them, sending emails to designated staff for non-compliant results over an internet connection.

QualiFormeD LINACWATCH / LINACVIEW allows the user to verify for every treatment, in real time, with email notifications on alert or failure, the following parameters:

- The position of each moving multi-leaf collimator (MLC) leaf; ●
- The position of MLC carriages and jaws;
- The percentage of monitor units (MUs) delivered; ●
- The gantry rotation angle; ●
- The collimator rotation angle;
- The beam on/off statistics; and
- . The reconstructed integrated fluence.

Additionally, after any number of treatments has been analyzed, QualiFormeD LINACWATCH / LINACVIEW allows the user to create RT Plans that can simulate the composite behavior of the analyzed logfiles. These RT Plans can be imported into the treatment planning system (TPS) to compare intended doses with those actually delivered, although this estimated dose does not include dosimetric changes due to patient setup or geometric changes. Adobe Acrobat® PDF reports documenting machine performance can be created at any point during treatment.

At the end of a course of treatment when the treatment series is closed, a composite RT Plan is automatically created that summarizes the composite behavior of all analyzed logfiles as well as two (2) final reports, a short and a comprehensive report, that documents all aspects of the treatment course.

Step and Shoot, Sliding Window, and Volumetric Modulated Arc Therapy (VMAT) IMRT techniques are supported.
