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 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.

AI/ML Overview

The provided text describes Fusion7D, a software program for registering and fusing medical images. However, it does not include detailed acceptance criteria or a study that specifically proves the device meets such criteria in terms of quantitative performance metrics, sample sizes, expert involvement, or statistical analysis.

The document is a 510(k) summary, which focuses on demonstrating substantial equivalence to predicate devices, rather than providing a detailed performance study with acceptance criteria.

Therefore, the following information cannot be extracted from the provided text:

  • A table of acceptance criteria and the reported device performance: This information is not present. The document describes the device's capabilities and intended use but does not quantify performance against specific criteria.
  • Sample size used for the test set and the data provenance: No performance study details are given.
  • Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not mentioned.
  • Adjudication method for the test set: Not mentioned.
  • If a multi-reader multi-case (MRMC) comparative effectiveness study was done, and the effect size of how much human readers improve with AI vs without AI assistance: This type of study is not described. The device is a registration tool, not an AI diagnostic aid in the sense of improving human reader performance on a diagnostic task, although it aims to "ease the comparison of image volume data."
  • If a standalone (i.e., algorithm only without human-in-the-loop performance) was done: Not explicitly stated or quantified in terms of performance. The document implies automated registration capabilities but doesn't provide a standalone performance evaluation against a gold standard.
  • The type of ground truth used (expert consensus, pathology, outcomes data, etc.): Not mentioned.
  • The sample size for the training set: No training data or set is mentioned, as this is more a description of the final device functionality rather than its development.
  • How the ground truth for the training set was established: Not applicable, as no training set is described.

Summary of what can be inferred about "acceptance criteria" and "study" implicitly from the document:

The "acceptance criteria" for Fusion7D, as implied by the 510(k) process, primarily revolve around demonstrating substantial equivalence to legally marketed predicate devices in terms of intended use, technological characteristics, and safety/effectiveness. The "study" largely consists of the submission itself, detailing the device's functionality and comparing it to existing, approved devices.

The document states:

  • "Fusion7D is a software program running on a PC platform, which brings into alignment (registers) pairs of images from different imaging modalities."
  • It supports "manual," "semi-automatic," and "automatic" registration, limited to "rigid body deformation."
  • It provides "standard visualization facilities" and allows "registration results to be displayed in a variety of ways."
  • Intended Use: "Fusion7D registers pairs of anatomical and functional volumetric images... as a means to ease the comparison of image data."

The FDA's approval letter confirms that the device was found "substantially equivalent" based on its comparison to the predicate devices listed (K010336, K983256, K992654). This substantial equivalence is the de facto "acceptance criteria" for this 510(k) submission, and the "study" is the submission argument itself.

Critical Definitions:

Image RegistrationThe alignment of one or more [medical] images to a reference imagein order to facilitate geometric comparison. This is a numericaloperation that results in the computation of an explicit mathematicaltransformation between every point in the registered image sets.
Image FusionRegistration forms the basis of image fusion in the sense that thegeometrical alignment of images is a prerequisite. The notion of"fusion" takes this a step further by considering how to visualize thecontent of different images representing the same object [organ,anatomical region, etc.]. Such techniques include the use of overlays,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.

MRIMRIMRIPET
MRICTMRISPECT
CTCTCTPET
CTSPECT

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.
