Intended Use

Syntegra™ is a software application for multi-modality image registration and diagnostic fusion. Images are registered and displayed in a "fused" (overlaid in the same spatial orientation) format to provide combined functional and anatomical data providing different angular perspectives for interpretation by trained professionals

Device Story

Syntegra is a software application for multi-modality image registration and diagnostic fusion. It takes multiple image data sets (e.g., PET, CT, SPECT) as input, aligns them so physical positions are coincident, and displays them in a blended, overlaid format. Users control the opacity of each data set to facilitate interpretation. The software provides 3D rendering techniques, including multi-planar reformatting, surface rendering with cut-planes, and maximum intensity projections. It also includes Region of Interest (ROI) tools for drawing 2D contours on transaxial planes, which can be exported to Radiation Therapy Planning systems for 3D volume generation. The device is intended for use by trained professionals in clinical settings on standard PC workstations. By providing combined functional and anatomical data, it assists clinicians in diagnostic interpretation and therapy planning.

Clinical Evidence

No clinical data provided. Substantial equivalence is based on technological comparison and intended use.

Technological Characteristics

Software application for Windows XP/Intel Pentium systems (min. 1GHz, 1GB RAM). Features multi-modality image registration, fusion display with user-adjustable opacity, 3D rendering (multi-planar reformatting, surface rendering, maximum intensity projections), and ROI contouring tools. Operates on standard PC workstations.

Indications for Use

Indicated for trained professionals requiring multi-modality image registration and diagnostic fusion to visualize combined functional and anatomical data for clinical interpretation.

Regulatory Classification

Identification

An emission computed tomography system is a device intended to detect the location and distribution of gamma ray- and positron-emitting radionuclides in the body and produce cross-sectional images through computer reconstruction of the data. This generic type of device may include signal analysis and display equipment, patient and equipment supports, radionuclide anatomical markers, component parts, and accessories.

#### Intended Use: E.

Syntegra™ is a software application for multi-modality image registration and diagnostic fusion. Images are registered and displayed in a "fused" (overlaid in the same spatial orientation) format to provide combined functional and anatomical data providing different angular perspectives for interpretation by trained professionals

#### Device Description: F.

Syntegra™ is a software application for multi-modality image registration and diagnostic fusion. This application exists within the predicate device, Gemini 16 (K032036). The Gemini 16 is an imaging system that combines Positron Emission Tomography (PET) and X-ray Computed Tomography (CT). This PET/CT device includes the processing station and applications contained within, such as image fusion. Syntegra™ may be offered as a standalone software application that has the capability to be utilized on any PC image processing workstations meeting the minimum hardware requirements to support the application.

Registration is the process of aligning two or more images from the same patient so that physical positions within each image are coincident. The images may be from the same imaging modality or different imaging modalities.

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

Fusion display is the visual combination of two image data sets that allows the data sets to be displayed simultaneously in a blended mode in the same screen window. The level of be arejected by user adjustable opacity values assigned to each data set. A common application of fusion display is the combination of physiological data from SPECT images and anatomical information from CT images.

Images are registered and displayed in a fused format to provide combined functional and anatomical data. The images are presented using various three-dimensional rendering techniques such as multi-planar reformatting, surface rendering with cut-planes, and maximum intensity projections.

Syntegra also offers Region of Interest tools. These are tools, which allow a user to draw two-dimensional contours around areas of interest on the transaxial image planes. The contours may then be exported to Radiation Therapy Planning systems, which use the two dimensional contours to generate three-dimensional volumes, which may be used in therapy planning.

The application operates on WindowXP/Intel Pentium computer systems with the following minimum requirements:

- Graphics Card: 24/32 bit color, support for 1400x1162 screen resolution .
- RAM: 1 GB .
- Processor: Pentium IV and above .
- Clock Speed: 1GHz clock speed .

#### Technological Comparison: G.

Syntegra and the image fusion software application within the predicate, Gemini (K032036), have similar indications for use and utilize similar methods for registration, fusion, and display of images from different modalities. Syntegra, like the predicate device also has the tools and capability to display the combined images for a more comprehensive image. The similarities and differences between the Syntegra and the predicate device are described in detail in Section E of this pre-market notification.

#### Conclusion: H.

Syntegra is substantially equivalent to the image fusion software application from the following predicate device, Gemini (K032036), based on similar intended use and technological comparison.
