Intended Use

AutoSPECT® produces images, which depict the three-dimensional distribution of radiopharmaceutical tracers in a patient. This software is intended to provide enhancements to gamma camera emission image processing by automating previously manual image processing functions, providing manual and automated motion correction, providing enhanced reconstruction algorithms that include resolution recovery, scatter correction, noise compensation, and attenuation correction via application of a transmission dataset.

Device Story

AutoSPECT is a software application for processing gamma camera SPECT data (cardiac, brain, total body, gated, MCD, SPECT-CT). It automates manual image processing tasks and provides manual/automated motion correction. The device utilizes enhanced reconstruction algorithms, including OSEM (Astonish SPECT), resolution recovery, scatter correction, noise compensation, and map-based attenuation correction using transmission datasets. It operates on a Windows XP PC platform. Clinicians use the software to process DICOM 3.0 compatible datasets, either individually or in batch mode. The output consists of reconstructed 3D images depicting radiopharmaceutical tracer distribution. These images assist physicians in diagnostic interpretation and clinical decision-making by providing improved image quality and standardized processing workflows.

Clinical Evidence

No clinical data provided. Substantial equivalence is based on technological comparison and the use of previously cleared basic data-processing algorithms combined with enhanced reconstruction techniques.

Technological Characteristics

Software-based image processing application. Compatible with DICOM 3.0 gamma camera datasets. Reconstruction algorithms: OSEM (Astonish SPECT), resolution recovery, scatter correction, noise compensation, and map-based attenuation correction. Platform: Windows XP Professional, Intel x86/Pentium >1 GHz, 512MB DRAM, 30GB disk space. Connectivity: 10/100 BaseTX Ethernet.

Indications for Use

Indicated for patients undergoing gamma camera emission imaging, including cardiac, brain, and other (bone, liver, etc.) SPECT, gated SPECT, Vantage SPECT, SPECT-CT, total body SPECT, and MCD/MCD-AC studies. Used for processing and reconstructing 3D radiopharmaceutical tracer distribution images.

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.

#### E. Intended Use:

AutoSPECT® produces images, which depict the three-dimensional distribution of radiopharmaceutical tracers in a patient. This software is intended to provide enhancements to gamma camera emission image processing by automating previously manual image processing functions, providing manual and automated motion correction, providing enhanced reconstruction algorithms that include resolution recovery, scatter correction, noise compensation, and attenuation correction via application of a transmission dataset.

#### F. Device Description:

AutoSPECT is a software application that produces images, which depict the threedimensional distribution of radiopharmaceutical tracers in a patient via automatic or manual processing. One or more cardiac SPECT, gated SPECT, or MCD cardiac data sets may be processed automatically using AutoSPECT. Additionally, one or more non-cardiac SPECT, gated SPECT, or MCD data sets may be processed manually. AutoSPECT contains basic data-processing algorithms that have been cleared previously; in addition to enhanced data reconstruction algorithms that include scatter correction, resolution recovery, map-based attenuation correction, and OSEM (Astonish SPECT) reconstruction.

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

The AutoSPECT software option may be used on images from a gamma camera system that are DICOM 3.0 compatible. The following data sets may be used:

- Cardiac, brain, or other (bone, liver, etc.) SPECT datascts .
- . Gated SPECT datasets
- . Vantage SPECT datasets
- SPECT-CT datasets .
- Total Body SPECT datasets
- MCD and MCD-AC datasets .

AutoSPECT provides the user three options for automatically processing cardiac datasets: AutoAll, Auto Recon, and Auto Reorient. Each option is described in greater detail in the software description section.

AutoSPECT also allows the user to process non-cardiac SPECT and MCD datasets. In this case, the operator manually positions the reconstruction limit lines to reconstruct transverse data sets. If necessary, the data set can be reoriented manually by positioning the azimuth, elevation, and twist lines to the desired locations.

In addition, the capability of processing groups of SPECT data sets in a batch mode fashion is provided. Once the operator has selected the datasets and determined the processing method, AutoSPECT processes the first dataset, followed by all remaining datasets without further interaction from the user.

AutoSPECT application runs on Microsoft Windows XP Professional environment. The minimum hardware requirements is listed:

- . Intel x86/Pentium class processor > 1 GHz ;
- Graphics capability must meet or exceed 1280x1024 pixels with 32 bit pixel . depth;
- . 30 Gb of disk space (minimum);
- . 512 Mb of DRAM (minimum);
- . 10/100 BaseTX Ethernet interface;
- . Port capable of supporting a dongle;
- . CD drive- capable of reading and writing:
- 56Kbps modem (minimum) .

{2}------------------------------------------------

### G. Technological Comparison:

AutoSPECT and the predicate, AutoSPECT Plus with InStill Motion Correction, have similar indication for use, utilize similar methods for motion correction, reconstruction, and display of images. AutoSPECT like the predicate device also has the tools for automated and manual processing of images. AutoSPECT will provide new enhanced data reconstruction algorithms that include scatter correction, resolution recovery, map-based attenuation correction, and OSEM (Astonish SPECT) reconstruction. The similarities and differences between AutoSPECT and the predicate device are described in detail in predicate comparison section of this pre-market notification.

#### H. Conclusion:

AutoSPECT is substantially equivalent to the following predicate device, AutoSPECT Plus with InStill Motion Correction (K992317) based on similar intended use and technological comparison.
