The summary describes software updates for image reconstruction and processing, but there is no mention of AI or ML technologies. The listed features are standard CT imaging techniques and iterative reconstruction methods.
No.
The device is clearly described as an imaging system (CT scanner) used to produce cross-sectional images for diagnostic purposes, not for therapeutic intervention.
Yes
Explanation: The device, a CT system, is intended to produce cross-sectional images of the body by reconstructing x-ray transmission data. These images are used by medical professionals to diagnose various conditions, classifying it as a diagnostic device.
No
The device is described as a new software version for an existing CT system (SOMATOM Definition Flash). While the submission focuses on the software update, the device itself is the CT system, which is a hardware device. The software is an integral part of the hardware system's operation and functionality.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to "produce cross-sectional images of the body by computer reconstruction of x-ray transmission data". This describes an imaging device used for diagnostic purposes on the body, not for testing samples in vitro (outside the body).
- Device Description: The description focuses on the software and features related to image acquisition, reconstruction, and processing from X-ray data. This aligns with an imaging system, not an IVD.
- Input Imaging Modality: The input is "x-ray transmission data", which is characteristic of imaging devices like CT scanners, not IVDs that typically analyze biological samples.
- Anatomical Site: The anatomical site is the "body", further indicating an in-vivo imaging device.
IVD devices are designed to perform tests on specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or treatment. This device does not perform such tests.
N/A
Intended Use / Indications for Use
The Siemens SOMATOM Definition Flash system is intended to produce cross-sectional images of the body by computer reconstruction of x-ray transmission data from either the same axial plane taken at different angles or spiral planes* taken at different angles.
(*spiral planes: the axial planes resulted from the continuous rotation of detectors and x-ray tube, and the simultaneous translation of the patient.)

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 claims of substantial equivalence.
Software Verification and Validation
Software Documentation for a Moderate Level of Concern software, per FDA's Guidance Document "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices" issued on May 11, 2005, is included as part of this submission.
Non-clinical tests (integration and functional) were conducted during the SOMATOM Definition Flash product development. The performance data demonstrates continued conformance with special controls for medical devices containing software.

Performance tests were conducted to test the functionality of the SOMATOM Definition AS Open configured with software version syngo® VA48. These tests have been performed to test the ability of the included features of the subject device. The results of these tests demonstrate that the subject device performs as intended. The result of all conducted testing was found acceptable to support the claim of substantial equivalence.
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 predicate devices were cleared based on non-clinical data as specified by recognized standards. Non-clinical data for the subject device was also gathered in this way The SOMATOM Definition Flash configured with software version syngo® VA48 has the same intended use and indication for use as the predicate devices.
The non-clinical data support the safety of the device and the software verification and validation demonstrate that the SOMATOM Definition Flash configured with software version syngo® SOMARIS/7 VA48 should perform as intended in the specified use conditions.
