Intended Use

The ADAC 3D-MSPECT application is intended to provide processing and 3-dimensional display of reconstructed Cardiac SPECT studies.

Device Story

3D-MSPECT is a software application for the ADAC Pegasys system; processes and displays reconstructed cardiac SPECT perfusion images. Inputs: cardiac SPECT data sets (stress, rest, delay, Vantage). Processing: computes left ventricular chamber volume, ejection fraction, and transient ischemic dilation (TID); generates 3D renderings of endocardial/epicardial surfaces and polar maps (perfusion, wall thickening, wall motion, reversibility). Output: 3D visualizations and quantitative metrics for physician review. Used in clinical settings by physicians to assess cardiac anatomical/physiological functionality and myocardial defects. Enables comparison of related data sets and creation/modification of patient 'Normals' files. Benefits: assists in diagnostic assessment of heart function and defect identification.

Clinical Evidence

Bench testing only. Image quality verified using a prototype of the application; results demonstrated image quality similar to predicate devices.

Technological Characteristics

Software application operating on ADAC Pegasys system. Performs quantitative analysis and 3D rendering of cardiac SPECT data. Supports slice-by-slice and 3D display modes. No specific hardware materials or connectivity standards cited.

Indications for Use

Indicated for processing and 3D display of reconstructed cardiac SPECT studies for patients undergoing cardiac perfusion imaging.

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.

#### D. Device Description:

3D-MSPECT is a software application designed to review and quantitatively analyze cardiac SPECT perfusion nuclear medicine patient studies. 3D-MSPECT operates as an independent application on the ADAC Pegasys system. The application provides tools for viewing standard and gated cardiac SPECT images on both a slice-by-slice basis and as a three-dimensional rendered image. Additionally, it provides a quantitative assessment of heart function by computing and displaying left ventricular chamber volume, ejection fraction, and transient ischemic dilation (TID) values and provides an assessment of the data set in comparison to similar patients. Physicians use this information to assess the anatomical and physiological functionality of the heart and analyze the presence of myocardial defects.

3D-MSPECT can be used to display the left ventricular endocardial and epicardial surfaces, polar maps indicating perfusion, wall thickening, wall motion, and reversibility, a 3D rendered image of the cardiac surfaces, and the

short axis, vertical long, and horizontal long slice data. These can be displayed for a single data set or as a comparison of related data sets (i.e., stress, rest, delay, or Vantage). Physicians can also use this application to create, modify and review Normals files from patient data available in the Pegasys database.

#### E. Indications for Use:

The ADAC 3D-MSPECT application is intended to provide processing and 3-dimensional display of reconstructed Cardiac SPECT studies.

- Technological Comparison: F.
The ADAC 3D-MSPECT, ADAC CEQUAL, and Sopha Sopha Sophy NXT Cardiac Software have similar indications for use and utilize similar types of data sets for analysis, with the exception of the Vantage data sets used by 3D-MSPECT. In addition, these applications perform similar quantifications (calculations) used to produce image displays of the data sets.

#### Testing II.

Images were generated using a prototype of the application. The quality of the images produced was verified to be similar to the quality of images produced by the predicate devices.

Dear Mr. Henkelman:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21. Parts 800 to 895. A substantially eculvalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (OS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.

This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at [phone]. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at [phone].
