The Multitom Rax is a stationary X-ray system for radiography and fluoroscopy. The Multitom Rax consists of a floor mounted patient table and ceiling suspended X-ray tube and a ceiling suspended solid state X-ray imager (SSXI). Together with an X-ray generator and a digital imaging system the Multitom Rax provides comprehensive image acquisition modes to support radiographic and fluoroscopic imaging procedures. X-ray tube and SSXI suspension movements are synchronized to provide rotation around a center. Series imaging acquired during the rotation are provided to 3D post-processing workstations.
The provided text is a 510(k) summary for the Siemens Multitom Rax, an X-ray imaging system. The submission focuses on demonstrating substantial equivalence to existing predicate devices rather than proving performance against specific acceptance criteria in a standalone clinical study. Therefore, much of the requested information regarding acceptance criteria, study design parameters (sample size, data provenance, ground truth establishment, expert qualifications, adjudication methods), and comparative effectiveness studies (MRMC, standalone algorithm performance) is not explicitly detailed in this document.
Here's a breakdown of the available information:
1. A table of acceptance criteria and the reported device performance
The document does not present a table with specific quantitative acceptance criteria or device performance metrics in the format of a clinical study. Instead, it relies on demonstrating compliance with recognized standards and substantial equivalence to predicate devices.
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
Not applicable. The submission does not describe a clinical test set with human subjects to evaluate performance against specific acceptance criteria. The "tests" mentioned are primarily non-clinical verification and validation activities and compliance with standards.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
Not applicable. No clinical test set with ground truth established by experts is described.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable. No clinical test set with adjudication is described.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
No MRMC comparative effectiveness study was done. The device described is an X-ray imaging system, not an AI-powered diagnostic algorithm for image interpretation.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
Not applicable. This is an X-ray imaging system, not a standalone AI algorithm.
7. The type of ground truth used (expert concensus, pathology, outcomes data, etc)
Not applicable. No clinical ground truth is described. The "ground truth" in this context refers to the successful verification against engineering specifications and compliance with safety standards for the device's components and functionality.
8. The sample size for the training set
Not applicable. This is an X-ray imaging system undergoing a 510(k) submission based on substantial equivalence, not an AI model requiring a training set.
9. How the ground truth for the training set was established
Not applicable, as there is no training set for an AI model.
Summary of the Study and Evidence Presented for Device Acceptance (Substantial Equivalence):
The Siemens Multitom Rax obtained a 510(k) clearance based on demonstrating substantial equivalence to two predicate devices:
The "study" that proves the device meets the acceptance criteria (substantial equivalence) is a combination of non-clinical verification and validation testing and compliance with recognized standards.
Here's the evidence presented:
- Indications for Use: The Multitom Rax has identical indications for use as the Primary predicate AXIOM Luminos dRF (K062623).
- Technological Characteristics:
- The Multitom Rax uses the same X-ray generator, X-ray tube, solid state X-ray imager (SSXI), digital imaging system, and image processing software as the Primary predicate AXIOM Luminos dRF.
- The system control (in-room or remote) is the same fashion as the Primary predicate AXIOM Luminos dRF.
- The mechanical design concept is the same as the Secondary predicate AXIOM Aristos FX Plus.
- Changes implemented involve enhanced movement flexibility of suspension arms, increased number of predefined automatic positions, optimized software algorithm for faster movement, and a more sophisticated collision software. These features were also available in the secondary predicate to some extent (e.g., automatic positioning).
- The automatic exposure control processes data from 5 dose measurement fields instead of 3 (compared to predicate devices).
- Increased number of organ programs, including additional pediatric applications.
- Non-Clinical Test Data:
- Design completed in accordance with Siemens Quality Management System Design Controls and Engineering.
- Verification and Validation testing were successfully conducted.
- Tests demonstrated the device is safe and effective, performs comparably to predicate devices, and is substantially equivalent.
- Tests included verification/validation testing to internal functional specifications (including software).
- Since the Multitom Rax uses the same SSXI as the Primary predicate and X-ray geometry and techniques are the same, clinical image comparisons involving SSXI were not conducted.
- Compliance documentation for software (Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices) was provided, including results of verification/validation tests for software requirements and risk hazards.
- Performance Standards Compliance:
- Confirmed compliance with 21 CFR 1020.30-32 Federal Performance Standards for X-Ray Fluoroscopic equipment.
- Complies with relevant voluntary safety standards for Electrical Safety and Electromagnetic Compatibility testing, specifically numerous IEC standards (e.g., IEC 60601-1, IEC 60601-1-2, IEC 60601-1-3, IEC 62366, ISO 14971, IEC 62304, IEC 60601-2-28, IEC 60601-2-54, IEC 61910-1, NEMA PS 3.1 - 3.20, IEC 60825-1, ISO 10993-1, IEC 60601-2-43).
- Conclusion: The verification/validation activities confirmed that device requirements were fulfilled, system functionality is consistent with user needs and intended uses, and the device performs as designed without raising new questions regarding safety or effectiveness, thus supporting a determination of substantial equivalence.

5. Device Description:
The Multitom Rax is a stationary X-ray system for radiography and fluoroscopy. The Multitom Rax consists of a floor mounted patient table and ceiling suspended X-ray tube and a ceiling suspended solid state X-ray imager (SSXI). Together with an X-ray generator and a digital imaging system the Multitom Rax provides comprehensive image acquisition modes to support radiographic and fluoroscopic imaging procedures. X-ray tube and SSXI suspension movements are synchronized to provide rotation around a center. Series imaging acquired during the rotation are provided to 3D post-processing workstations.
6. Indication for Use:
The Multitom Rax is intended to be used as a universal diagnostic imaging system for radiographic and fluoroscopic studies. Using a digital flat detector, it can perform a range of applications including general R/F, anqiography and pediatric examinations.
The Multitom Rax is a device intended to visualize anatomical structures by converting a pattern of X-ray into a visible image. The system has medical applications ranging from but not limited to gastrointestinal examinations, cranial, skeletal, thoracic and lung exposures as well as examination of the urogenital tract. The unit may also be used in lymphography, endoscopy, myelography, venography, pediatrics, arthrography, interventional radiography, digital angiography and digital subtraction angiography (DSA).
The Multitom Rax may be used for outpatient and emergency treatment, as well as for mobile transport (wheelchair and bed) examinations.
The Multitom Rax is not for mammography examinations.
7. Substantial Equivalence:
The new device Multitom Rax is within the same classification regulation for the same indication for use as the Primary predicate AXIOM Luminos dRF (K062623, cleared 08/22/2007). The mechanical design is compared to the Secondary predicate the AXIOM Aristos FX Plus (K061054, cleared 05/09/2006). Documentation is provided to support a claim of substantial equivalence to these Siemens' predicate devices.
8. Summary of Technological Characteristics of the Subject Device as Compared with the Predicate Devices:
Changes implemented for the subject device include hardware and software changes. The subject device, Multitom Rax, uses the same X-ray generator, the same X-ray tube and the same SSXI with the same digital imaging system and same image processing software as the Primary predicate AXIOM Luminos dRF. The system can be controlled in the room or remotely in the same fashion as the Primary predicate AXIOM Luminos dRF.
{6}------------------------------------------------
The mechanical design concept is the same as for the Secondary predicate the AXIOM Aristos FX Plus.
The subject device was changed in reqard to movement flexibility of the suspension arms and increased number of predefined automatic positions of tube and SSXI. Dedicated positions for certain examinations can be stored with the organ programs. When such an organ program is selected the Multitom Rax automatically moves to that position. This feature was also available with the secondary predicate AXIOM Aristos FX Plus.
The software algorithm for this movement has been optimized to find the fastest way to that position. There are hardware and software collision control features in place as well. The scanner offers both automated tube-todetector and detector-to-tube alignment. This feature is called: "RAXalign." Due to the increase in movement speed and the addition of circular movement a more sophisticated collisions software was implemented.
The automatic exposure control processes the data from 5 dose measurement fields instead of 3 compared with the predicate devices. The number of organ programs was increased and additional programs are provided for pediatric applications.
Summary of Non-Clinical Test Data:
Multitom Rax is a new device based on components used with both predicate devices AXIOM Luminos dRF(K062623) and AXIOM Aristos FX Plus (K061054) The Multitom Rax design was completed in accordance with Siemens Quality Management System Design Controls and Engineering, standards compliance, and Verification and Validation testing were successfully conducted. Tests were performed on the Multitom Rax which demonstrated that the device is safe and effective, performs comparably to the predicate devices, and is substantially equivalent to the predicate devices. Tests included verification/validation testing to internal functional specifications (including software). The Multitom Rax uses the same solid state X-ray imager (SSXI) as the Primary predicate. X-ray geometry and techniques are the same so that clinical image comparisons involving SSXI were not conducted. Documentation provided demonstrates compliance of the new device to all FDA requirements stated in Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices. including results of verification/validation tests to software requirements and software risk hazards.
Performance testing confirmed that the Multitom Rax complies with 21 CFR 1020.30-32 Federal Performance Standards for X-Ray Fluoroscopic equipment and with relevant voluntary safety standards for Electrical Safety

10 Summary of Clinical Tests:
For the subject of this premarket submission, Siemens did not do an evaluation of the clinical image quality as required by the "Guidance for the Submission of 510(k)'s for Solid State X-ray Imaging Devices." because the subject device uses the same SSXI as the Primary predicate device.
11. 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 warnings are incorporated into the system design. In addition the Multitom Rax 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.
12. Conclusion as to Substantial Equivalence:
The Multitom Rax is intended for the same indications for use as the Primary predicate AXIOM Luminos dRF. The operating environment is the same and mechanical design the same as the Secondary predicate the AXIOM Aristos FX Plus. Siemens concludes via the documentation provided in this 510(k) submission that the Multitom Rax is substantially equivalent to the AXIOM Luminos dRF (K051133 cleared 06/01/2005) and the AXIOM Aristos FX Plus (K061045 cleared 05/09/2006).
