The document describes a standard PET/CT imaging system and its technical specifications. There is no mention of AI, ML, or related concepts in the intended use, device description, or performance studies.
No
The device is described as an "imaging system" intended for "producing attenuation corrected PET images" and to "aid in radiotherapy treatment planning, therapy guidance and monitoring, and in interventional radiology procedures," as well as for "detection, localization, diagnosis, staging, restaging, monitoring, and/or follow up." These are diagnostic and planning functions, not therapeutic applications that involve treating a condition.
Yes
Explanation: The "Intended Use / Indications for Use" section explicitly states that the raw and image data generated by the device is an "aid in; detection, localization, diagnosis, staging, restaging, monitoring, and/or follow up, of abnormalities, lesions, tumors, inflammation, infection, organ function, disorders, and/or disease". Additionally, the "Device Description" section labels it as a "PET/CT diagnostic imaging system".
No
The device description explicitly states it is a "PET/CT diagnostic imaging system combining a Positron Emission Tomography (PET) System and a Computed Tomography (CT) System" and lists hardware components like a scanning system, power distribution unit, table system, and detector rings. This indicates it is a hardware-based medical device with integrated software, not a software-only device.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs analyze samples taken from the body (in vitro), such as blood, urine, or tissue. This device is an imaging system that scans the patient's body directly (in vivo) using PET and CT technology.
- The intended use describes imaging the distribution of radiopharmaceuticals within the patient and producing images for diagnostic purposes. This is a characteristic of in vivo imaging devices, not IVDs.
- The device description details the physical components of a PET/CT scanner, including detectors and scanning systems. This aligns with the description of an imaging device.
Therefore, this device falls under the category of an in vivo diagnostic imaging system, not an In Vitro Diagnostic.
N/A
Intended Use / Indications for Use
The Imaging system of positron emission and X-ray computed tomography is a PET/CT system for producing attenuation corrected PET images. It is intended to be used by qualified health care professionals for imaging the distribution and localization of any positron-emitting radiopharmaceutical in a patient, for the assessment of metabolic (molecular) and physiologic function in patients, with a wide range of sizes and extent of disease, of all ages.
Imaging system of positron emission and X-ray computed tomography is intended to image the whole body, head, heart, brain, lung, breast, bone, the gastrointestinal and lymphatic systems, and other organs.
