No
The description mentions "iterative recurrent linear regressions" and "spectral deconvolution analysis," which are traditional signal processing and statistical methods, not explicitly AI or ML techniques. There is no mention of AI, ML, or related terms like neural networks or deep learning.
No.
The device is a software application intended for image quality and quantification improvement by scatter reduction in nuclear medicine images, not for treating specific medical conditions.
No
The device is a software application intended for image quality and quantification improvement by scatter reduction in nuclear medicine images. It processes existing images to make them clearer for interpretation, but it does not directly diagnose a condition or disease.
Yes
The device is described as a "software application" and an "option" for an existing workstation, focusing solely on image processing and scatter reduction through spectral analysis. There is no mention of any new or modified hardware components being part of this submission.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is focused on improving image quality and quantification in nuclear medicine images by reducing scatter. This is a function related to the processing and analysis of medical images, not the analysis of biological samples (like blood, urine, or tissue) to diagnose or monitor a disease.
- Device Description: The device is described as a software application that performs spectral deconvolution analysis on nuclear spectra to reduce scatter. This is an image processing technique applied to data acquired from a nuclear medicine scan.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples, detecting specific analytes, or providing diagnostic information based on the analysis of biological materials.
IVDs are devices used to examine specimens derived from the human body to provide information for the diagnosis, prevention, or treatment of a disease or condition. This device operates on the image data itself, not on a biological specimen.

Intended Use / Indications for Use
The Photon Energy Recovery (PER) Option is intended for image quality and quantification improvement by scatter reduction in planar and tomographic nuclear medicine images. This option enables Gated SPECT acquisition in multi-energy window format which allows normal GSPECT processing along with PER scatter correction on the summed data. It can be used for acquisitions of single or multi-peak isotope as well as simultaneous multi-isotope images.

Device Description
The Photon Energy Recovery (PER) option is a software application for reducing the Compton scatter contribution in nuclear images. This enables scatter correction of single as well as multipeak isotope imaging. In addition it allows for the correction of cross-talk down scatter in simultaneous multiisotope imaging. The method is based on a spectral deconvolution analysis using iterative recurrent linear regressions on nuclear spectra. These spectra are broken down into multiple energy windows. This submission provides an extension on the PER features of the currently legally marketed device, GE Vision Nuclear Medicine Workstation - K012568.

Description of Change or Modification
The original PER application featured in the predicate device. GE Vision Nuclear Medicine Workstation (K012568), focuses on Compton scatter reduction for improved contrast and better spatial resolution. The new PER application extends this capability for nuclear cameras by enabling gated SPECT acquisition in multi-energy window format, allowing normal GSPECT processing along with PER scatter correction on the summed data.
The following features are included in the PER Option:
- Scatter correction for single isotope Static, SPECT, and . Gated scans
- . Scatter and cross-talk correction for simultaneous dual and multi-isotope imaging
Intended Use of Device
The Photon Energy Recovery (PER) Option is intended for image quality and quantification improvement by scatter reduction in planar and tomographic nuclear medicine images. This option enables Gated SPECT acquisition in multi-energy window format which allows normal GSPECT processing along with PER scatter correction on the summed data. It can be used for acquisitions of single or multi-peak isotope as well as simultaneous multi-isotope images.

Summary of Studies
Bench and clinical data show that the PER corrected simultaneous dualisotope images are similar to the conventional single isotope images.
Conclusion
In the opinion of ELGEMS Ltd., the Photon Energy Recovery (PER) Option is substantially equivalent in terms of safety and effectiveness to the PER capabilities featured in the legally marketed GE Vision Nuclear Medicine Workstation (K012568).
