Intended Use
The uMI 550 PET/CT is a diagnostic imaging system that combines two existing imaging modalities - PET and CT. The quantitative distribution information of PET radiopharmaceuticals within the patient body measured by PET can assist healthcare providers in assessing the metabolic and physiological functions. CT provides diagnostic tomographic anatomical information as well as photon attenuation for the scanned region. The accurate registration and fusion of PET and CT images provides anatomical reference for the findings in the PET images. This system is intended to be operated by qualified healthcare professionals to assist in the detection, localization, diagnosis, staging, restaging, treatment planning and treatment response evaluation for diseases and disorders in, but not limit to, oncology, cardiology and neurology.
Device Description
The uMI 550 PET/CT system is a combined multi-slice X-Ray Computed Tomography and Positron Emission Tomography scanner. This system is intended to be operated by qualified healthcare professionals for performing diagnostic imaging examinations. The spatial alignment and precise image registration between PET and CT ensure the PET and CT images of the same region can be fused accurately for reading. PET measures the distribution of PET radiopharmaceuticals inside the human body quantitatively. CT produces the anatomical information of the same scanned region, and provides accurate localization for the findings in the PET images. The attenuation information contained in the CT images can be utilized in the PET image reconstruction to ensure quantitation accuracy. The PET system has time-of-flight capability with a timing resolution of 395ps. It has a 240mm-long axial field of view (FOV) and a system sensitivity ~11cps/kBq. The uMI 550 PET/CT system also includes a patient table, a workstation with associated software installed. The software is used for patient management, data management, scan control, image reconstruction and image reading. All patient images produced by the system conform to the DICOM 3.0 standard.
More Information

Not Found

No
The document does not mention AI, ML, or related terms, and the description focuses on standard PET/CT technology and image processing.

No
The device is described as a "diagnostic imaging system" intended for "detection, localization, diagnosis, staging, restaging, treatment planning and treatment response evaluation," which are diagnostic rather than therapeutic functions.

Yes

The "Intended Use / Indications for Use" section explicitly states that the system is intended to "assist in the detection, localization, diagnosis, staging, restaging, treatment planning and treatment response evaluation for diseases and disorders." The "Device Description" also mentions it is for "performing diagnostic imaging examinations."

No

The device description explicitly states it is a "combined multi-slice X-Ray Computed Tomography and Positron Emission Tomography scanner" and includes hardware components like a patient table and the scanner itself, in addition to software.

Based on the provided text, the uMI 550 PET/CT device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases or conditions.
  • uMI 550 Function: The uMI 550 is an in vivo imaging system. It works by detecting the distribution of radiopharmaceuticals within the patient's body using PET and providing anatomical information using CT. It does not analyze samples taken from the body.
  • Intended Use: The intended use clearly states it's a "diagnostic imaging system" used to "assist in the detection, localization, diagnosis, staging, restaging, treatment planning and treatment response evaluation for diseases and disorders" by imaging the patient directly.

Therefore, the uMI 550 PET/CT falls under the category of medical imaging devices, not in vitro diagnostics.
