• Applicant: Mirada Solutions , Ltd.
• Product Code: LLZ · Radiology
• Decision Date: Apr 26, 2002
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 892.2050
• Device Class: Class 2
• Attributes: Software as a Medical Device

Intended Use

Fusion7D registers pairs of anatomical and functional volumetric images (e.g. MRI-SPECT, MRI-PET, CT-SPECT, CT-PET), or pairs of anatomical volumetric images (e.g. MRI-MRI, CT-CT and MRI-CT) as a means to ease the comparison of image volume data by the clinician. The result of the registration operation aims to help the clinician obtain a better understanding of the joint information that would otherwise have to be compared visually. This is useful for a wide range of clinical and therapeutic applications. It is important to note that the clinician retains the ultimate responsibility for making the pertinent diagnosis based on their standard procedures including visual comparison of the separate unregistered images. Fusion7D is a complement to these standard procedures.

Device Story

Fusion7D is PC-based software for multi-modality image registration and visualization. It accepts volumetric DICOM data from anatomical (CT, MRI) and functional (PET, SPECT) imaging modalities. The device performs rigid body registration (3D translation and rotation) via manual, semi-automatic (landmark-based), or automatic methods. The software provides a GUI for orthogonal slicing, zooming, panning, window/level control, and image overlays (transparency/thresholding). Clinicians use the registered output to visualize joint anatomical and functional information, aiding in clinical and therapeutic decision-making. The device serves as a complement to standard diagnostic procedures; the clinician retains ultimate responsibility for diagnosis based on visual comparison of original unregistered images.

Clinical Evidence

No clinical data provided. Substantial equivalence is based on technological characteristics and intended use comparisons to legally marketed predicate devices.

Technological Characteristics

PC-based software; DICOM-compliant; rigid body transformation (3D translation and rotation) registration engine; GUI-based visualization (orthogonal slicing, panning, zooming, window/level, overlays).

Indications for Use

Indicated for clinicians requiring geometric alignment and visualization of anatomical (MRI, CT) and functional (SPECT, PET) volumetric image pairs to facilitate comparison of joint information for clinical and therapeutic applications.

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).

| Classification Name: | Class II: Picture Archiving and Communications System<br>(892 2050) Product Code: LLZ Image Processing System |

# Critical Definitions:

| Image Registration | The alignment of one or more [medical] images to a reference image<br>in order to facilitate geometric comparison. This is a numerical<br>operation that results in the computation of an explicit mathematical<br>transformation between every point in the registered image sets. |
|--------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Image Fusion | Registration forms the basis of image fusion in the sense that the<br>geometrical alignment of images is a prerequisite. The notion of<br>"fusion" takes this a step further by considering how to visualize the<br>content of different images representing the same object [organ,<br>anatomical region, etc.]. Such techniques include the use of overlays,<br>semi-transparent renderings, etc. |

NOTE: In the context of this application, the term "registration" and "fusion" may be used interchangeably to describe geometric alignment of images and subsequent visualization.

# Device description:

Fusion7D is a software program running on a PC platform, which brings into alignment (registers) pairs of images from different imaging modalities. Fusion7D also includes functionality to read, display, and save the original volumetric data and the results of the registration operation by means of a graphic user interface that includes visualization, file browsing and control of input and output as described in the following text.

# Registration Engine

Medical images can be divided into anatomical images (e.g. CT and conventional MRI), and functional images (e.g. SPECT and PET). Fusion7D provides two registration solutions: 1. It enables the comparison of pairs of anatomical images (to assess changes in anatomical structures) and 2. It correlates the structures seen in an anatomical dataset with the activity detected in functional images.

{1}------------------------------------------------

| Anatomical<br>to Anatomical | | Anatomical<br>to Functional | |
|-----------------------------|--------|-----------------------------|--------|
| Source | Target | Source | Target |
| MRI | MRI | MRI | PET |
| MRI | CT | MRI | SPECT |
| CT | CT | CT | PET |
| | | CT | SPECT |

Fusion7D is therefore useful to register the following pairs of datasets:

The registration operation can be a) manual: whereby the user defines the transformation that brings the two datasets into as close alignment as possible, b) semi-automatic: in which the user inputs a series of landmarks in one dataset and the software provides matching landmarks in the other, and c) automatic: in which the software requires no user input and finds the transformation between the two datasets based on the characteristics of the images. In all these cases the transformation is limited to a rigid body deformation (i.e. 3D translation and rotation).

#### Data/Image Browsing and Visualization

The Fusion7D software incorporates standard visualization facilities to visualize the input DICOM data and the results of the registration operations. This simple visualization GUI includes:

- orthogonal and any-plane slicing of the volumetric data (but no 3D reconstruction), .
- . whole and region of interest zooming,
- panning. .
- . window and level controls,
- image overlays for which the transparency, threshold and colormap is user controlled. ●

The Fusion7D software allows the registration results to be displayed in a variety of ways including: the overlay of one dataset on another, the simultaneous binding of cursors in two volumes and the generation of a split pane image.

#### Intended Use:

Fusion7D registers pairs of anatomical and functional volumetric images (e.g. MRI-SPECT, MRI-PET, CT-SPECT, CT-PET), or pairs of anatomical volumetric images (e.g. MRI-MRI, CT-CT and MRI-CT) as a means to ease the comparison of image data. The result of the registration operation aims to help the clinician obtain a better understanding of the joint information that would otherwise have to be compared visually. This is useful for a wide range of clinical and therapeutic applications. It is important to note that the clinician retains the ultimate responsibility for making the pertinent diagnosis based on their standard procedures, including visual comparison of the separate unregistered images. Fusion7D is a complement to these standard procedures.
