#### 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
