Intended Use

Velocity is a software package that provides the physicians a means for comparison of medical data including imaging data that is DICOM compliant. It allows the display, annotation, volume operation, volume rendering, registration, and fusion of medical images as an aid during use by diagnostic radiology, oncology, radiation therapy planning and other medical specialties. Velocity is not intended for mammography.

Device Story

Velocity is a standalone medical imaging software application for oncology and radiotherapy workflows. It ingests DICOM-compliant imaging data (PET, SPECT, CT, MR, RT Dose) from various modalities and time points. The software provides tools for image display, manual/automatic registration (rigid and deformable), fusion, and segmentation (atlas-based). It calculates pixel intensity differences, Standardized Uptake Values (SUV), and biological effective dose (BED) scaling. It supports Y-90 microsphere dosimetry by converting SPECT to dose. Used by clinicians (radiologists, oncologists, therapists) on off-the-shelf computers to facilitate treatment planning and plan review. Outputs include annotated images, registered volumes, and dose reports, which are imported/exported to PACS or radiation treatment planning systems. The device aids clinical decision-making by enabling longitudinal comparison and adaptive radiotherapy planning, potentially improving treatment accuracy.

Clinical Evidence

No clinical data included. Safety and effectiveness supported by non-clinical software verification and validation testing conducted in accordance with FDA guidance for major level of concern software.

Technological Characteristics

Standalone software application; runs on Windows 7/10 or macOS. Supports DICOM import/export. Features include rigid/deformable image registration, atlas-based segmentation, volume rendering, and Y-90 dosimetry. Connectivity via network/PACS integration. Software is classified as major level of concern.

Indications for Use

Indicated for physicians requiring comparison of DICOM-compliant medical imaging data. Used in diagnostic radiology, oncology, and radiation therapy planning for display, annotation, volume rendering, registration, and fusion of images. Not indicated for mammography.

Regulatory Classification

Identification

A medical image management and processing system is a device that provides one or more capabilities relating to the review and digital processing of medical images for the purposes of interpretation by a trained practitioner of disease detection, diagnosis, or patient management.

MIM Y90 Dosimetry (K172218) was determined to be a predicate for the RapidSphere SPECT Microsphere Dosimetry feature. Both features:

- are intended for post-treatment absorbed dose calculation and evaluation
- are compatible with Y90 PET and SPECT image types
- and use the Local deposition model for dose calculation.

## Performance Data:

## Software Verification and Validation Testing

Software verification and validation was conducted and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." The software for this device was considered as a "major" level of concern.

Clinical Tests No clinical tests have been included in this pre-market submission.

## Conclusions

The non-clinical data support the safety of the device and the software verification and validation demonstrate that the Velocity device performs as intended. Varian therefore considers Velocity 4.0 to be safe and effective and to perform at least as well as the predicate device.
