The summary describes a combined SPECT/CT system that uses CT images for attenuation correction and localization, which are standard image processing techniques, not AI/ML. There is no mention of AI, ML, or related concepts like deep learning, training sets, or performance metrics typically associated with AI/ML algorithms.
No
The device is described as performing diagnostic imaging applications, not therapeutic interventions.
Yes
The "Intended Use / Indications for Use" section explicitly states that the system is used to "perform combined cardiac SPECT and CT diagnostic imaging applications" and "for clinical diagnostic purposes."
No
The device description explicitly states it is a "back-to-back combination of the Ventri 1.1 SPECT scanner and the LightSpeed 7.1 CT scanner, sharing a common LightSpeed 7.1 patient table," indicating it includes significant hardware components.
Based on the provided information, the GE Discovery NM/CT 570c system is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The GE Discovery NM/CT 570c system is an imaging system. It uses SPECT and CT modalities to create images of the inside of the patient's body. It does not perform tests on samples taken from the body.
- Intended Use: The intended use clearly states "perform combined cardiac SPECT and CT diagnostic imaging applications" and "performing nuclear cardiac imaging procedures for detection and imaging of racer uptake in the patient body". This describes an imaging process, not an in vitro test.
Therefore, the GE Discovery NM/CT 570c system falls under the category of medical imaging devices, not In Vitro Diagnostics.

Intended Use / Indications for Use
The intended use of the GE Discovery NM/CT 570c system is primarily to perform combined cardiac SPECT and CT diagnostic imaging applications, including CT-based SPECT attenuation correction and functional-anatomical mapping (registration and fusion).
The GE Discovery NM/CT 570c system intended uses include performing nuclear cardiac imaging procedures for detection and imaging of racer uptake in the patient body for clinical diagnostic purposes as well as performing general Head & Body Computed Tomography (CT) applications

Device Description
The GE Discovery NM/CT 570c system is a back-to-back combination of the Ventri 1.1 SPECT scanner (K080124) and the LightSpeed 7.1 CT scanner (K061817), sharing a common LightSpeed 7.1 patient table. In addition to providing CT and SPECT standalone capabilities, it uses the CT images to correct for non-uniform attenuation of the SPECT images and to facilitate localization of the emission activity in the patient anatomy.

Device Description
The GE Discovery NM/CT 570c system is a back-to-back combination of the Ventri 1.1 SPECT scanner (K080124) and the LightSpeed 7.1 CT scanner (K061817), sharing a common LightSpeed 7.1 patient table. In addition to providing CT and SPECT standalone capabilities, it uses the CT images to correct for non-uniform attenuation of the SPECT images and to facilitate localization of the emission activity in the patient anatomy.
Description of Change or Modification
The LightSpeed 7.1 CT System (K061817), the Ventri 1.1 SPECT System (K080124) and the Xeleris 2 Processing and Review Workstation (K051673), had been modified to accommodate for the GE Discovery NM/CT 570c system, by including means to align gantries, share emergency stop circuits, a common table and additional processing software for use of CT for purposes of SPECT attenuation correction.
Intended Use of Device
The intended use of the GE Discovery NM/CT 570c system is primarily to perform combined cardiac SPECT and CT diagnostic imaging applications, including CT-based SPECT attenuation correction and functional-anatomical mapping (registration and fusion).
The GE Discovery NM/CT 570c system intended uses include performing nuclear cardiac imaging procedures for detection and imaging of radioisotope tracer uptake in the patient body for clinical diagnostic purposes as well as performing general Head & Body Computed Tomography (CT) applications
Summary of Studies
Data acquired with uniform phantom shows that SPECT-CT attenuation-corrected images are more uniform than SPECT images without attenuation correction. The images also demonstrate the localization capabilities of the SPECT-CT.
Conclusion
In the opinion of GE MEDICAL SYSTEMS F.I. HAIFA, the GE Discovery NM/CT 570c system is substantially equivalent in terms of safety and effectiveness to the legally marketed Ventri 1.1 (K080124), the legally marketed LightSpeed 7.1 (K061817), the legally marketed Infinia LightSpeed (K061817) and the legally marketed Xeleris 2 Processing and Review Workstation (K051673), based upon similar intended use and system performances.

Dear Mr. Devine:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate 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) that do not require approval of a premarket approval application (PMA), 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 (PMA), 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 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
