GuideShot option provides remote in-room display/controls for interventional procedures. Used in clinical settings by qualified physicians to aid diagnosis. DICOM interface allows data transfer to external devices.

Clinical Evidence

Clinical evaluation compared the SCENARIA Phase 2 to the predicate SCENARIA system (K101888). Bench testing evaluated dose profile, image noise, Modulation Transfer Function (MTF), slice thickness, sensitivity profile, slice plane location, and CT dose index. Results confirmed performance is comparable to the predicate.

Technological Characteristics

System components (gantry, tube, table) identical to predicate. Complies with IEC 60601-1, 60601-1-1, 60601-1-2, 60601-1-3, 60601-2-32, and 60601-2-44.

Indications for Use

Indicated for head, whole body, cardiac, and vascular CT imaging in patients of all ages. Used for axial, helical, gated, or dynamic acquisition modes. Supports interventional imaging via remote display/controls.

Regulatory Classification

Identification

A computed tomography x-ray system is a diagnostic x-ray system intended to produce cross-sectional images of the body by computer reconstruction of x-ray transmission data from the same axial plane taken at different angles. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.

### Scientific Concepts

The SCENARIA Phase 2 system uses 64-slice CT technology, where the X-ray tube and detector assemblies are mounted on a frame that rotates continuously around the patient using slip ring technology. The solid-state detector assembly design collects up to 64 slices of data simultaneously. The X-ray sub-system features a high frequency generator. X-ray tube, and collimation system that produces a fan beam X-ray output. The system can operate in a helical (spiral) scan mode where the patient table moves during scanning. As the X-ray tube/detector assembly rotates around the patient, data is collected at multiple angles.

The collected data is then reconstructed into cross-sectional images by a high-speed reconstruction sub-system. The images are displayed on a Computer Workstation, stored, printed, and archived as required. The workstation is based on current PC technology using the Windows™ operating system.

### Physical and Performance Characteristics

The SCENARIA Phase 2 system consists of a Gantry, Operator's Workstation, Patient Table, high-Frequency X-ray Generator, and accessories. The system performance is similar to the predicate device.

### Performance Comparison

A clinical evaluation comparison was conducted with the SCENARIA Phase 2 system and the original SCENARIA System (K101888) and found to be substantially equivalent as documented in Section 12 - Performance Testing - Clinical.

In addition, evaluations were conducted for dose profile, image noise, Modulation Transfer Function (MTF), slice thickness and sensitivity profile, slice plane location, and CT dose index as documented in Section 11 - Performance Testing - Bench.

The evaluation results confirm the performance characteristics of the SCENARIA Phase 2 are comparable to the predicate device and support our conclusion that the SCENARIA Phase 2 system is substantially equivalent.

## Device Technological Characteristics

The SCENARIA PHASE 2's Gantry, X-ray Tube, X-ray Generator, and Patient Table specifications are the same as the SCENARIA System (K101888). Likewise, the Helical Scanning, Image Processing, Display, Image Storage, and Performance features are equivalent to the predicate device. Lastly, the features related to dose which are available on the predicate device are also included on the SCENARIA PHASE 2. See Section 4 - Comparison to Predicate Device for additional information.

Therefore, the SCENARIA Phase 2 system is technologically equivalent in concept, function, and performance to the predicate device.

## Conclusions

The SCENARIA Phase 2 system has been developed and validated according to applicable standards. Testing has proven that the system is safe and effective for the indicated use. Risk and hazard analysis shows that there are no new safety issues associated with this system as compared with the predicate device.
