No
The device description explicitly states that the SCENARIA View 4.2 is a multi-slice computed tomography system consisting of hardware components such as a Gantry, Operator's Workstation, Patient Table, High- Frequency X-ray Generator, and accessories, in addition to 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 (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- Device Function: The SCENARIA View 4.2 system is a Computed Tomography (CT) scanner. 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 describes acquiring images of the whole body, including the head, and post-processing these images. This is consistent with an imaging device, not an IVD.
- Device Description: The description details the physical components and how the system generates images using X-rays and detectors. This aligns with a CT scanner.
Therefore, the SCENARIA View 4.2 system is an imaging device, not an In Vitro Diagnostic.

Device Description
The SCENARIA View 4.2 is a multi-slice computed tomography system that uses x-ray data to produce cross-sectional images of the body at various angles.
The SCENARIA View 4.20system 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.
The SCENARIA View 4.2 system consists of a Gantry, Operator's Workstation, Patient Table, High- Frequency X-ray Generator, and accessories.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Evaluations were conducted for dose profile, image noise, Modulation Transfer Function (MTF), slice thickness and sensitivity profile, slice plane location, and CT dose index. The feature of having tilt for helical scan is a combination of features that are included in the predicate device and do not affect the diagnosis. Prospective ExamSplit is a modification of the image information and also does not affect the diagnosis. The AutoPositioning feature supports the operator's work prior to the CT examination, and does not affect the diagnosis.
The AutoPositioning function was verified to be working correctly through system testing. To ensure the AutoPositioning option was working correctly, various cases were tested to verify if the AutoPositioning function will show up as an option. The following case testing was performed:
- . Install the software as an application added to the existing system that does not have AutoPositioning installed.
- . Indicate the name of this software and the version number as the version information in an environment where AutoPositioning option is installed.
- Enable AutoPositioning function in an environment where AutoPositioning is already installed.
- . Prohibit the AutoPositioning function when this software is not installed in an environment where the AutoPositioning option is not installed.
All test results performed as expected.
Verification and validation testing was performed on ExamSplit function as well to ensure it works as expected. A mock procedure was carried out during which ExamSplit function was turned ON and the scan was carried out as listed in the operation manual. The following criteria had to meet in order for the ExamSplit testing to pass:
- After scan, an automatic analysis queue for the main recon of the original inspection is . registered and executed.
- . After the multi-recon is completed, the automatic analysis queue for the original inspection multi-recon is registered and executed.
- . After Exam Split execution is completed, an automatic analysis queue for PES is registered and executed.
- Exam Split starts running after scan, and Multi Recon starts running Exam Split after recon . is completed
All testing passed the above requirements.
The evaluation results confirm the performance characteristics of the SCENARIA View 4.2 are comparable to the predicate device and support our conclusion that the subject system is substantially equivalent.

Physical and Performance Characteristics
The SCENARIA View 4.2 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
Evaluations were conducted for dose profile, image noise, Modulation Transfer Function (MTF), slice thickness and sensitivity profile, slice plane location, and CT dose index. The feature of having tilt for helical scan is a combination of features that are included in the predicate device and do not affect the diagnosis. Prospective ExamSplit is a modification of the image information and also does not affect the diagnosis. The AutoPositioning feature supports the operator's work prior to the CT examination, and does not affect the diagnosis.
The AutoPositioning function was verified to be working correctly through system testing. To ensure the AutoPositioning option was working correctly, various cases were tested to verify if the AutoPositioning function will show up as an option. The following case testing was performed:
- . Install the software as an application added to the existing system that does not have AutoPositioning installed.
- . Indicate the name of this software and the version number as the version information in an environment where AutoPositioning option is installed.
- Enable AutoPositioning function in an environment where AutoPositioning is already installed.
- . Prohibit the AutoPositioning function when this software is not installed in an environment where the AutoPositioning option is not installed.
All test results performed as expected.
Verification and validation testing was performed on ExamSplit function as well to ensure it works as expected. A mock procedure was carried out during which ExamSplit function was turned ON and the scan was carried out as listed in the operation manual. The following criteria had to meet in order for the ExamSplit testing to pass:
- After scan, an automatic analysis queue for the main recon of the original inspection is . registered and executed.
- . After the multi-recon is completed, the automatic analysis queue for the original inspection multi-recon is registered and executed.
- . After Exam Split execution is completed, an automatic analysis queue for PES is registered and executed.
