Intended Use

Autofuse is a software package that provides 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. Autofuse is not intended for mammography.

Device Story

Autofuse is a standalone medical imaging software application for radiotherapy professionals. It ingests DICOM-compliant medical images (CT, MR, PET, RT Dose) from PACS or other clinical systems. The software provides tools for image display, annotation, volume rendering, and co-registration (including deformable registration) of multi-modal images. It allows users to draw Regions of Interest (ROI) and export results to radiation treatment planning systems. Used in clinical settings on off-the-shelf computers, the device assists clinicians in visualizing and analyzing anatomical and functional data to support treatment planning workflows. It does not perform automated segmentation or manual registration editing. The output is viewed by clinicians to inform clinical decision-making in oncology and radiation therapy.

Clinical Evidence

No clinical data. Bench testing only. Software verification and validation were performed in a simulated clinical environment using virtual machines to confirm device specifications meet user needs and intended use, following FDA guidance and AAPM standards (TG-53, TG-132).

Technological Characteristics

Software-only device; runs on off-the-shelf (OTS) hardware. OS: Ubuntu 22.04. Connectivity: DICOM-compliant (DIMSE/TLS). Features: Rigid and deformable image registration, volume rendering, ROI contouring, and DICOM-RT import/export. No hardware components. Software development follows ISO 13485 and 21 CFR 820 design controls.

Indications for Use

Indicated for physicians in diagnostic radiology, oncology, and radiation therapy planning to compare, display, annotate, register, and fuse DICOM-compliant medical images. Not intended 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. The software components may provide advanced or complex image processing functions for image manipulation, enhancement, or quantification that are intended for use in the interpretation and analysis of medical images. Advanced image manipulation functions may include image segmentation, multimodality image registration, or 3D visualization. Complex quantitative functions may include semi-automated measurements or time-series measurements.

Special Controls

*Classification.* Class II (special controls; voluntary standards—Digital Imaging and Communications in Medicine (DICOM) Std., Joint Photographic Experts Group (JPEG) Std., Society of Motion Picture and Television Engineers (SMPTE) Test Pattern).
