This device is a diagnostic imaging system (CT scanner) used to generate images for aid in diagnosis, treatment preparation, and radiation therapy planning, not to provide therapy itself.
Yes
The "Intended Use / Indications for Use" section explicitly states that the images delivered by the system "can be used by a trained physician as an aid in diagnosis" and "as an aid in diagnosis, treatment preparation and radiation therapy planning." It also mentions "low dose lung cancer screening," which is a diagnostic application.
No
The device description explicitly states it is a "Computed Tomography X- ray System" and lists new/modified hardware components (Touch Panels, New Gantry and Patient Table Covers, Stellar RT Detector). This indicates it is a hardware system with integrated software, not a software-only device.
Based on the provided information, this 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, conditions, or infections.
- Device Function: The described device is a Computed Tomography (CT) system. It generates images of the inside of the body using X-rays. This is an in vivo imaging technique, meaning it is performed on a living organism, not on a sample taken from the body.
- Intended Use: The intended use clearly states that the system generates and processes images of patients by computer reconstruction of x-ray transmission data. The images are used as an aid in diagnosis, treatment preparation, and radiation therapy planning. This aligns with the function of a medical imaging device, not an IVD.
Therefore, while the device is a medical device used for diagnosis, it does not fit the definition of an In Vitro Diagnostic.

8
potential hazards are controlled during development, verification and validation testing. In order to minimize electrical, mechanical, and radiation hazards. Siemens adheres to recognized and established industry practice and standards.
VIII. Conclusions
The predicate devices were cleared based on the results of non-clinical testing including verification and validation, phantom tests, and supportive literature. The subject device is also tested using the same methods as used for the predicate devices. The nonclinical data supports the safety of the device and the hardware and software verification and validation demonstrates that the SOMATOM Confidence should perform as intended in the specified use conditions. The data included in this submission demonstrates that the SOMATOM Confidence performs comparably to the predicate device that is currently marketed for the same intended use. Since both devices were tested using the same methods, Siemens believes that the data generated from the SOMATOM Confidence testing supports a finding of substantial equivalence.
