Intended Use
The SCENARIA Phase 3 system is indicated for head, whole body, cardiac and vascular X-ray Computed Tomography applications in patients of all ages. The images can be acquired in either axial, helical, gated or dynamic modes. The volume datasets acquired by the SCENARIA Phase 3 can be post processed by the SCENARIA Phase 3 to provide additional information. Post processing capabilities included in the SCENARIA Phase 3 software include CT angiography (CTA), Multi-planar reconstruction (MPR) and volume rendering. Volume datasets acquired by the SCENARIA Phase 3 can be transferred to external devices via a DICOM standard interface. The guideShot Option adds a remote in-room display and controls to support interventional imaging. The device output can provide an aid to diagnosis when used by a qualified physician.
Device Description
The SCENARIA Phase 3 is a multi-slice computed tomography system that uses x-ray data to produce cross-sectional images of the body at various angles. The system consists of a Gantry, Operator's Workstation, Patient Table, High-Frequency X-ray Generator, and accessories. The system uses 128-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.
More Information

Not Found

No
The summary describes standard CT technology and image processing techniques (MPR, volume rendering) without mentioning AI or ML. The performance testing focuses on basic CT parameters and clinical image examples, not AI/ML performance metrics.

No
The device is described as a diagnostic imaging system (X-ray Computed Tomography) used to produce cross-sectional images of the body, which aids in diagnosis. It does not perform any therapy or treatment.

Yes

Explanation: The "Intended Use / Indications for Use" section states, "The device output can provide an aid to diagnosis when used by a qualified physician." This explicitly indicates its role in diagnosis.

No

The device description clearly outlines multiple hardware components including a Gantry, Operator's Workstation, Patient Table, High-Frequency X-ray Generator, and accessories, indicating it is a hardware system with integrated software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body, such as blood, urine, or tissue, to provide information for diagnosis, monitoring, or screening.
  • Device Function: The SCENARIA Phase 3 system is an X-ray Computed Tomography (CT) system. It uses X-rays to create images of the inside of the body. It does not analyze specimens taken from the body.
  • Intended Use: The intended use clearly states it's for "head, whole body, cardiac and vascular X-ray Computed Tomography applications in patients of all ages." This involves imaging the patient directly, not analyzing samples.
  • Device Description: The description details the components of a CT scanner (Gantry, Operator's Workstation, Patient Table, etc.) and how it acquires images using X-rays. There is no mention of handling or analyzing biological specimens.

Therefore, the SCENARIA Phase 3 system falls under the category of an in vivo diagnostic imaging device, not an in vitro diagnostic device.

Device Description

Function

The SCENARIA Phase 3 is a multi-slice computed tomography system that uses x-ray data to produce cross-sectional images of the body at various angles.

Scientific Concepts

The SCENARIA Phase 3 system uses 128-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 3 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

Evaluations were conducted for dose profile, image noise, Modulation Transfer Function (MTF), slice thickness and sensitivity profile, slice plane location, and CT dose index and also found to be substantially equivalent.

A clinical evaluation comparison was conducted with the SCENARIA Phase 3 system and the SCENARIA Phase 2 System (K123509) and found to be substantially equivalent.

A rationale analysis was then conducted and the results are contained in Table 1.

Testing TypeRationale Analysis
Performance Testing - BenchWe generated bench data based on IEC61223-3-5.
We confirmed that the items (Dose Profile, Noise, Mean CT number and Uniformity, Sparial Resolution, Tomographic Section Thickness and Sensitivity Profile, Tomographic Plane Location, CT dose index) which we tested met the conditions of 21 CFR 1020.33(c) or (g).
This shows that SCENARIA Phase3 has equivalent basic performance as the predicate device, SCENARIA Phase2.
Performance Testing - ClinicalWe provide five clinical image examples which we judged to be sufficient to judge a clinical usability. The five covered the general anatomy outlined in the indications for use and are comparable to the anatomy examples provided for the predicate.

Table 1 Performance Comparison Analysis

The analysis confirms the performance characteristics of the SCENARIA Phase 3 system are comparable to the predicate device and support our conclusion that the SCENARIA Phase 3 system is substantially equivalent.

Device Technological Characteristics

The technological characteristics of the SCENARIA Phase 3 and the predicate device are listed in Table 2.
