No
The summary describes a hybrid imaging system combining existing SPECT and CT technologies with image registration and fusion capabilities, but there is no mention of AI or ML being used for image processing, analysis, or any other function.
No
The device is described as an "imaging system" used for "diagnoses" by providing "functional information about metabolic processes" and "structural or anatomical information" through fused images. There is no mention of treating or preventing a disease, injury, or condition.
Yes
The device is an imaging system that combines nuclear medicine and CT images to provide information for "accurate and comprehensive diagnoses," indicating its role in identifying or characterizing diseases.
No
The device description explicitly states it is a "hybrid SPECT/CT system" and describes physical components like gantries and acquisition consoles, indicating it is a hardware system with integrated software, not a software-only device.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for the diagnosis, treatment, or prevention of disease.
- Device Function: The description clearly states that the Griffin system is an imaging system that acquires images of the distribution of radiopharmaceuticals in the body and x-ray transmission images. It works by imaging the patient directly, not by analyzing specimens taken from the patient.
- Intended Use: The intended use is to produce and display images for anatomical localization and potentially for transfer to other systems like radiation therapy planning. This is consistent with an in vivo imaging device, not an in vitro diagnostic.
The device is a medical imaging system used for in vivo imaging, not an in vitro diagnostic device.

Intended Use / Indications for Use
Griffin is an imaging system combining the acquisition of single photon nuclear medicine images and images from an x-ray computed tomography system. Griffin may produce non-attenuation corrected and attenuation corrected images of the distribution of radiopharmaceuticals in the body as well as x-ray transmission images. The CT transmission data may be used to produce attenuation corrected nuclear medicine images. The nuclear medicine images and the CT images may be registered and displayed in a fused format (overlaid in the same orientation) to provide combined single photon and anatomical data for anatomical localization of the nuclear medicine data. Griffin may be used either as a separate single photon system, a separate CT system or as a combined CT and single photon system. The nuclear medicine and CT images may be transferred to other systems such as a radiation therapy planning system. The Griffin Imaging System should only be used by trained healthcare professionals.

Device Description
The Griffin SPECT/CT Imaging System (Griffin) is a hybrid SPECT/CT system for performing CT studies, general nuclear medicine studies, or SPECT/CT scquentially (dual-modality studies) wherein the SPECT and CT studies may be automatically co-registered and displayed in fused form. Because the natures of the imaging modalities, they provide different information; the SPECT study yields functional information about metabolic processes and the CT study yields structural or anatomical information. As radionuctides become more tissue specific, diagnoses from nuclear images alone will be more difficult without the general anatomical detail less specific agents provide. Thus fused SPECT and CT images will provide the information required for accurate and comprehensive diagnoses. Griffin is constructed from two existing systems, the Skylight Imaging System (K031705) and the Brilliance CT (K012009). The Griffin has two acquisition consoles. One console is placed in the acquisition room itself, consistent with the SPECT convention, and the other console is placed in the shielded scanner control room, as required for CT. The acquisition stations provide a single user interface for both SPECT and CT patient acquisition set-up. The SK Ylight and Brilliance system gantries remain intact as major subsystem components located within a common integrated housing. The combined Griffin SPECT-CT Imaging System is designed so that the system can operate in three modes: CT only, SPECT only, and combined SPECT/CT performed sequentially. No modifications have been made to either system, which would affect system performance. Griffin is intended for use primarily as an imaging system combining the acquisition of single photon nuclear medicine images and images from an x-ray computed tomography system. The same clinical protocols and procedures are available on the Griffin Imaging System as in the predicate SPECT or CT systems. Acquired SPECT and CT images on the Griffin may be registered and displayed in a fused format (overlaid in the same orientation) to provide combined single photon and anatomical data to provide anatomical localization of the nuclear medicine image.

specific agents provide. Thus fused SPECT and CT images will provide the information required for accurate and comprehensive diagnoses.

One console is placed in the acquisition room itself, consistent with the SPECT convention, and the other console is placed in the shielded scanner control room, as required for CT.

No modifications have been made to either system, which would affect system performance.
Griffin is intended for use primarily as an imaging system combining the acquisition of single photon nuclear medicine images and images from an x-ray computed tomography system. The same clinical protocols and procedures are available on the Griffin Imaging System as in the predicate SPECT or CT systems. Acquired SPECT and CT images on the Griffin may be registered and displayed in a fused format (overlaid in the same orientation) to provide combined single photon and anatomical data to provide anatomical localization of the nuclear medicine image.
G. Comparison to Predicate Device:
The Griffin SPECT/CT Imaging System, like the predicate devices, SKYlight Imaging System and the Brilliance CT are similar in that all the devices consist of a full functional SPECT and CT system. The patient may have a diagnostic SPECT and CT scan performed consecutively without having to move the patient. The Griffin provides a mean to reach the diagnostic decision faster than the conventional way of imaging patients with both SPECT and CT systems in separate locations. The differences are overall system dimensions, room size requirements, and ease of use.
The combined Griffin SPECT-CT Imaging System is designed so that the system can operate in three modes: CT only, SPECT only, and combined SPECT/CT performed sequentially. The major difference is that the Griffin system has a common integrated housing for the major subsystem components. Griffin also provides a new dedicated SPET/CT table to allow the patient to be scanned on both systems in a single acquisition session. The common table also allows for parametric registration.
