No
The summary describes a standard CT system with image processing capabilities and mentions clinical and non-clinical testing, but there is no mention of AI, ML, or related concepts in the intended use, device description, or performance studies.
No
The device is a Computed Tomography (CT) system intended for generating and processing images for diagnostic purposes, specifically as an aid in diagnosis and for lung cancer screening. It does not perform any therapeutic function.
Yes
The input explicitly states that "The images delivered by the system can be used by a trained physician as an aid in diagnosis." This directly indicates its role in the diagnostic process.
No
The device description explicitly states it is a "Computed Tomography X-ray System" and features "two continuously rotating tube-detector systems," which are hardware components. While it includes software for image processing and control, it is not solely software.
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. They are used outside of the body ("in vitro").
- Device Function: This device is a Computed Tomography (CT) system. It generates images of the inside of the patient's body using X-rays. This is an in vivo (within the living body) imaging technique.
- Intended Use: The intended use is to generate and process images of patients to aid in diagnosis. This is a diagnostic imaging tool, not a test performed on a sample outside the body.
Therefore, while it is a diagnostic device, it falls under the category of medical imaging systems, not in vitro diagnostics.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The National Lung Screening Trial (NLST), sponsored by the National Cancer Institute, is used to support the additional lung cancer screening Indications for Use. The study was a randomized trial of screening with the use of low-dose CT compared to chest radiography to determine whether screening with low-dose CT could reduce mortality from lung cancer. The study start date was August. 2002 and the completion date was October. 2010. The interpretation task with CT for this study was to detect lung nodules of 4mm diameter or greater.
Clinical images were evaluated to demonstrate performance for Dual Source Dual Power mode. Clinical experience phrased in peer reviewed articles support the performance and effectiveness of several features provided with SOMATOM Drive.

6. Summary of Technological Characteristics of the Subject Device as Compared with the Predicate Devices:
The SOMATOM Drive provides the same technological characteristics in terms of materials, energy source and control mechanisms when compared to the predicate devices. The performance data of the X-ray tube and software features for the subject device SOMATOM Drive have been improved in comparison to the predicate device as described below:
X-Ray Tube/kV Steps Improvements:
The SOMATOM Drive includes two STRATON MX Sigma X-ray tubes, which are a modification of the X-ray tube to the predicate device (SOMATOM Definition Flash). This modification enables higher mA at lower kV levels. 70 kV and 80 kV (High Power 70 and High Power 80) in comparison to predicate device (SOMATOM Definition Flash).
The STRATON MX Sigma also enables consistent 10 kV steps from 70 to 140 kV, which were introduced as part of the predicate device (SOMATOM Force) and adds 90 kV. 110 kV and 130 kV steps in comparison to the predicate device (SOMATOM Definition Flash).
Tube Collimator Improvement
The SOMATOM Drive includes the Tin Filter (selective photon shield) as cleared in the predicate device (SOMATOM Definition Flash) on the collimator of both X-ray tubes, whereas the predicate device (SOMATOM Definition Flash) only had this on one X-ray tube.
Dual Power (full detector width)
The SOMATOM Drive allows the use of both tubes at the same kV with a routine pitch and full detector width, providing a doubling of the mA available in the examination (Dual Power Mode). The predicate device (SOMATOM Definition Flash) allows the use of both tubes at the same kV with a routine pitch only at half detector width.

The intended use and fundamental scientific technology remain unchanged from the predicate devices. The Indication for Use and technological characteristics are similar for the subject and predicate devices. Any differences in technological characteristics between the subject device and predicate devices do not raise different questions of safety and effectiveness. As such, Siemens believes that the subject device is substantially equivalent to the predicate devices.
7. Nonclinical Testing
The features described in this premarket notification are supported with verification and validation testing. Non clinical tests, including dosimetry and image performance, were conducted for the SOMATOM Drive during product development. The risk analysis was completed and risk control implemented to mitigate identified hazards. The test results show that all of the software specifications have met the acceptance criteria. Verification and validation testing of the device was found acceptable to support the claim of substantial equivalence.
Siemens claims conformance to the following standards: IEC 60601-1/A2: 2005; IEC 60601-2-44:2009 +A1:2012; XR-29: 2013; ISO/IEC 14971:2007; IEC 62304: Ed. 1.0 2006, IEC 61223-2-6: 2006, 61223-3-5: 2004, XR 25, ISO/IEC 10918-1: 1994, DICOM NEMA PS 3.1 - PS 3.20.

SIEMENS
The performance data demonstrates continued conformance with special controls for medical devices containing software. Non-clinical tests (integration and functional). including phantom test were conducted during the SOMATOM Drive product development. The Risk analysis was completed, and risk control implemented, to mitigate identified hazards. The test results show that all of the software specifications have met the acceptance criteria.
Additional provided supporting data
The National Lung Screening Trial (NLST), sponsored by the National Cancer Institute, is used to support the additional lung cancer screening Indications for Use. The study was a randomized trial of screening with the use of low-dose CT compared to chest radiography to determine whether screening with low-dose CT could reduce mortality from lung cancer. The study start date was August. 2002 and the completion date was October. 2010. The interpretation task with CT for this study was to detect lung nodules of 4mm diameter or greater.
8. Clinical Testing
Clinical images were evaluated to demonstrate performance for Dual Source Dual Power mode. Clinical experience phrased in peer reviewed articles support the performance and effectiveness of several features provided with SOMATOM Drive.
9. General Safety and Effectiveness Concerns:
The device labeling contains instructions for use as well as necessary cautions and warnings to provide for safe and effective use of the device. Risk management is ensured via a hazard analysis, which is used to identify potential hazards. These 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.
10.Conclusion as to Substantial Equivalence:
The subject device non-clinical data similarly supports the safety of the software with verification and validation testing. Verification and validation testing demonstrates that the SOMATOM Drive performs as intended. The non-clinical test data demonstrates that the SOMATOM Drive performance is comparable to the predicate devices that are currently marketed for the same intended use.
For SOMATOM Drive, Siemens used the same testing with the same workflows as was used to clear the predicate devices. Since both devices were tested using the same methods. Siemens believes that the data generated from the SOMATOM Drive testing supports a finding of substantial equivalence.
