### 5. Device Description:
The SOMATOM Scope and SOMATOM Scope Power configured with software version syngo® CT VC28 (SOMARIS/5 VC28) are whole body X-ray computed tomography scanners which operate with SOMARIS/5 software. SOMARIS/5 is a windows based program used for patient management, data management, X-ray scan control, image reconstruction, and image archive/evaluation.
The SOMATOM Scope and SOMATOM Scope Power configured with software version syngo® CT VC28 (SOMARIS/5 VC28) are able to transfer the acquired CT image data for image evaluation, using the DICOM standard.
New software version syngo® CT VC28 supports the addition of eCockpit, eStart, eMode, eSleep, a Table Footswitch, Adaptive Signal Boost, and Gantry tilt Speed up.
#### eCockpit
The SOMATOM Scope and SOMATOM Scope Power will support a marketed bundle of features designed to support more efficient usage of system tube power. These features will be marketed under the name, "eCockpit," and comprised of the following:
#### · eMode
ECO Mode (eMode) is a software feature, which uses pre-set values to reduce tube power (mA) and increase scan time, while keeping the dose unchanged. With this reduction in tube power, tube life can be increased. There is a click button (eAdjust) to upload eMode. The usage of the ECO Mode (eMode) is recorded in the tube usage history.
#### · eStart
eStart is a software option that extends the tube lifetime by pre-warming the tube before a scan. The system provides a recommendation to the user to perform eStart to warm up the tube each time the scanner has not been used for scanning in the last 30 minutes. This functionality helps to protect the tube and extend the tube lifetime.
{5}------------------------------------------------
Image /page/5/Picture/1 description: The image shows the word "SIEMENS" in a sans-serif font. The letters are a light blue color. The background is white.
#### · eSleep
eSleep is a software option designed to save energy by stopping gantry rotation during scan breaks.
### Table Footswitch
Foot Switch located on the bottom edge of the patient table allowing table lifting and lowering. Speeds up patient preparation and keeps the operator hands sterilized.
## Gantry tilt Speed up
Faster gantry tilt speed helps in dealing with higher patient throughput.
### IRIS
IRIS is an approach to iterative reconstruction that works to intelligently solve the trade-off between reconstruction times and image quality. In an iterative reconstruction, a correction loop is introduced into the Image generation process. To avoid long reconstruction times, IRIS is applied to raw data reconstruction only once. During this initial raw data reconstruction, a master volume is generated that contains the full amount of raw data information, but at the expense of significant image noise. The following iterative corrections are then consecutively performed in the image space, removing image noise without degrading image sharpness.
### Adaptive Signal Boost
Adaptive Signal Boost amplifies low signals when high attenuation is present - such as when imaging obese patients or patients with metal implants - and further reduces streaks and noise.
#### 6. Summary of Technical Characteristics of the Subject Device as Compared with the Predicate Device:
The SOMATOM Scope and SOMATOM Scope Power, both configured with software version syngo® CT VC28 (SOMARIS/5 VC28), do not have significant changes in materials, energy source, or technological characteristics when compared to the predicate devices.
The differences between the legally marketed predicate devices and the SOMATOM Scope and SOMATOM Scope Power are as follows:

# SIEMENS
equivalent to the predicate device in terms of safety and effectiveness. All testing and validation has been completed.
#### 8. Indications for Use:
The SOMATOM Scope and the SOMATOM Scope Power are 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 xray tube, and the simultaneous translation of the patient.)
#### 9. General Safety and Effectiveness Concerns:
The device labeling contains instructions for use and any 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. To minimize electrical, mechanical, and radiation hazards, Siemens adheres to recognized and established industry practice and standards.
### 10. Conclusion as to Substantial Equivalence:
In summary, Siemens is of the opinion that the SOMATOM Scope and the SOMATOM Scope Power configured with software version syngo® CT VC28 (SOMARIS/5 VC28) software package do not introduce any new potential safety risks and are substantially equivalent to and performs as well as the predicate devices.
