The document describes a standard mobile fluoroscopy system with image processing capabilities, but there is no mention of AI, ML, or related concepts. The performance studies focus on image quality compared to a predicate device, not on AI/ML-driven performance metrics.
No
The device is an X-ray imaging system used for diagnosis and image-guided procedures, not for direct treatment of conditions.
No
The device is an imaging system used to provide X-ray images of anatomical structures and does not inherently diagnose conditions; diagnosis is performed by a medical professional interpreting the images.
No
The device description clearly outlines hardware components like a C-arm with an X-ray source and flat panel detector, and a monitor trolley. This indicates it is a physical medical device with integrated software, not a software-only device.
Based on the provided information, the Cios Alpha is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use clearly states that the device is designed to provide X-ray imaging of anatomical structures of the patient during clinical applications. This involves imaging the patient directly, not analyzing samples taken from the patient.
- Device Description: The description details a mobile fluoroscopy system with a C-arm and monitor trolley, used for acquiring and processing X-ray images of the patient.
- Lack of IVD Characteristics: IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. The Cios Alpha does not perform this function.
The Cios Alpha is a medical imaging device used for diagnostic and interventional procedures performed directly on the patient.

Device Description
The Cios Alpha is a mobile fluoroscopy system designed for the surgical environment. The Cios Alpha provides comprehensive image acquisition modes to support orthopedic and vascular procedures. The system consists of two major components:
- a) The C-arm with X-ray source on one side and the flat panel detector on the opposite side. The c-arm can be angulated in both planes and be lifted vertically, shifted to the side and moved forward/backward by an operator.
- b) The monitor trolley providing image processing, review and patient data entry. The monitor trolley may contain an optional hardcopy (paper) printer and navigational equipment as well.

For the subject of this premarket submission, Siemens did not perform a formal clinical trial but did conduct a customer use test. In this test the Cios Alpha has been evaluated in a clinical environment for 8 weeks. More than 70 patients have been examined.
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Customer use test, More than 70 patients.
Key results: The investigators' opinion was that in this test phase the new Cios Alpha provided an even better, more detailed image quality as compared to the ARCADIS Avantic (predicate device). This includes the aortic procedures as well as the peripheral vascular structure representation i.e. the vascular representation of the foot.

SIEMENS
Cios Alpha is similar to the technology used with the predicate ARCADIS Avantic. A new GUI (graphical user interface) supports the user in the operation of the system.
8. Summary of Technological Characteristics of the Subject Device as Compared with the Predicate Device:
The Cios Alpha design is based on the ARCADIS Avantic and the experience Siemens has with more than 30 years with predicate mobile fluoroscopy C-arms (SIREMOBILE series). The advent of solid state detectors created a need to use this technology for mobile fluoroscopic systems too. The detector replaces the image intensifier and the TV camera (1k x 1k pixel matrix). The imaging system was upgraded to support the processing of up to 1536 pixel 16bit image matrix. Full DICOM compatibility and a new graphical user interface provide networking and an intuitive operation. X-ray generation is similar to the predicate with a 25% increase in output power. Pulsed fluoroscopy, similar to the predicate, helps to reduce dose exposure for long procedures.
The following table compares the dominant performance data of the subject device with the predicate device to substantiate equivalence of both devices.

It was the investigators opinion that in this test phase the new Cios Alpha provided an even better, more detailed image quality as compared to the ARCADIS Avantic (predicate device). This includes the aortic procedures as well as the peripheral vascular structure representation i.e. the vascular representation of the foot. The complete clinical evaluation is included in the attachment.
12. General Safety and Effectiveness Concerns:
Instructions for use are included within the device labeling, and the information provided will enable the user to operate the device in a safe and effective manner. Several safety features including visual and audible wamings are incorporated into the system design. In addition the Cios Alpha is continually monitored, and if an error occurs, the system functions will be blocked and an error message will be displayed.
Furthermore the operators are health care professionals familiar with and responsible for the X-ray examinations to be performed. To minimize electrical, mechanical and radiation hazards, Siemens adheres to recognized and established industry practice, and all equipment is subject to final performance testing.
Conclusion as to Substantial Equivalence: 13.
The Cios Alpha is intended for similar indications for use as the predicate ARCADIS Avantic. The imaging properties (X-ray source, output power and field of view) are similar. The most significant difference is the use of a solid state detector instead of an image intensifier. It is Siemens opinion, that the Cios Alpha is substantially equivalent to the ARCADIS Avantic (K051133, cleared 06/01/2005).
