The document describes a combined PET/CT imaging system and its intended use, focusing on image acquisition, attenuation correction using CT data, and image fusion for localization. There is no mention of AI or ML in the device description, intended use, or performance studies. The "Mentions AI, DNN, or ML" and "Mentions image processing" fields are explicitly marked as "Not Found".
No.
The device is used for imaging, assessment, evaluation, and diagnosis, which are diagnostic functions, not therapeutic.
Yes.
The "Intended Use / Indications for Use" section states that the device "can assist in the evaluation and diagnosis of lesions, disease and organ function" and "can also be used as a stand-alone head and whole body multislice computed tomography (CT) diagnostic imaging system."
No
The device description explicitly states it is a "combination of the Advance NXi PET Scanner and the LightSpeed CT Scanner," which are hardware components. The summary describes a physical imaging system, not just software.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health. This testing is done outside of the body.
- Discovery LS Function: The GE Discovery LS System is an imaging device. It works by detecting radiation emitted from radiopharmaceuticals injected into the patient's body. It then creates images of the distribution of these radiopharmaceuticals within the body. This is an in vivo (within the living body) process, not an in vitro process.
- Intended Use: The intended use clearly states it's for "head and whole body attenuation corrected Positron Emission Tomography (PET) imaging and localization of emission activity in patient anatomy." This describes an imaging procedure performed on a living patient.
Therefore, based on the provided information, the GE Discovery LS System is a medical imaging device, not an In Vitro Diagnostic device.

Intended Use / Indications for Use
The GE Discovery LS System is intended for head and whole body attenuation corrected Positron Emission Tomography (PET) imaging and localization of emission activity in patient anatomy by means of integrated PET and CT images.
The Discovery LS is to be used by trained health care professionals for imaging the distribution of radiopharmaceuticals in the body for the assessment of metabolic (molecular) and physiologic functions. This can assist in the evaluation and diagnosis of lesions, disease and organ function such as (but not limited to) cancer, cardiovascular disease, and brain dysfunction. This can also assist in radiotherapy planning.
The Discovery LS can also be used as a stand-alone head and whole body multislice computed tomography (CT) diagnostic imaging system.

Device Description
The Discovery LS CT-PET System is a combination of the Advance NXi PET Scanner (K003849) and the LightSpeed CT Scanner (K000300, K002978). In addition to providing CT and PET stand-alone capabilities, it uses the CT images to correct for nonuniform attenuation of the PET images and it uses integrated CT and PET images to localize emission activity in the patient anatomy. Discovery LS has capabilities for imaging all available PET tracers and CT contrast agents and can provide inherently reqistered anatomical and functional information via an integrated user interface.
