Intended Use

VERIQA is a software package for display, evaluation and digital processing of medical image data sets and treatment plans in radiation oncology. VERIQA software is a tool for evaluation and data management of digital images and treatment plan information. It supports the medical imaging modalities CT, MR, PET according to the ACR/NEMA DICOM 3.0 standard and other modalities. VERIQA supports the following applications: a) Receiving, transmitting, storing, display, and processing of medical images and DICOM objects. b) Creating, displaying and printing of reports containing medical images. c) Image registration, fusion display, and review of medical images for treatment evaluation and treatment planning. d) Localization and definition of structures such as tumors and normal tissue in medical image sets. e) Creation, transfer, and modification of contours and dose distributions such as quantitative analysis, aiding adaptive radiation therapy, transferring contours and dose distributions to radiation treatment planning systems, and archiving contours and dose distributions for patient follow-up and management. f) Secondary Monte Carlo dose calculation for patient specific quality assurance. VERIQA must not be used while a patient is present. VERIQA must not be used for treatment planning.

Device Story

VERIQA is a software package for radiation oncology quality assurance. It ingests DICOM-RT data, including medical images (CT, MR, PET) and treatment plans. The device performs secondary Monte Carlo 3D dose calculations to verify treatment plan accuracy; it also supports image registration, fusion, and contouring of tumors and normal tissue. Operated by medical physicists, dosimetrists, or oncologists in a clinical setting, the software provides quantitative analysis, dose-volume histograms, and 3D-gamma distribution comparisons against the original treatment planning system (TPS). Outputs include processed images, reports, and modified contours/dose distributions saved in DICOM-RT format. The system features an automated alert mechanism (color-coded status: red/orange/green) and email notifications to assist clinicians in evaluating treatment plan quality. By providing an independent dose verification, the device helps ensure the accuracy of radiation therapy delivery, potentially improving patient safety by identifying discrepancies before treatment.

Clinical Evidence

Bench testing only. Software verification and validation testing demonstrated that VERIQA fulfills design specifications and intended use, confirming equivalence to predicate devices.

Technological Characteristics

Modular software platform supporting DICOM 3.0 standard. Features include 3D Monte Carlo dose calculation engine, image registration/fusion algorithms, and contouring tools. Operates on standard medical imaging data (CT, MR, PET). Connectivity via DICOM-RT network protocols. Software-based analysis with automated alert/notification system.

Indications for Use

Indicated for use by qualified medical professionals (radiologists, nuclear medicine physicians, radiation oncologists, dosimetrists, medical physicists) for evaluation and data management of digital medical images and treatment plans in radiation oncology. Contraindicated for use while a patient is present and for primary treatment planning.

Dear Sandor-Csaba Ats:

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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for

### Substantial Equivalence 5

## 5.1 Technological Characteristics

The primary technologic characteristic of VERIQA can be broken up into 3 modules of functionality.

- a) The usage of three-dimensional imaging information and beam intensity information in DICOM-RT format to compute a dose distribution (also in DICOM-RT format) and a comparison of this independent calculation to the TPS dose distribution.
- b) Visualization and storage of CT/MR and PET-CT images, structure sets and dose distributions in DICOM-RT format.
- c) Contouring and image registration on the base of CT/MR images.

These technological characteristics are believed to be substantially equivalent to the predicate devices as seen in the below table.

### Performance Data 6

Software verification and validation testing results were conducted and submitted according to appropriate bench testing methods.

It was demonstrated that VERIQA fulfils the design specification and its intended use, and that it is equivalent to the predicate devices.

### Summary 7

The comparison of the indications for use, the technological characteristics, the performance, safety and effectiveness of the predicate devices and the subject device has shown that the VERIQA software is as safe and effective as the predicate devices and that the application is as well or better. With respect to the device, no new questions of safety and effectiveness could be determined.
