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.

Study Details

Sample size used for the test set and the data provenance:
- The document does not specify a numerical "sample size" in terms of patient cases for testing.
- The performance evaluations for image quality and dose (Dose Profile, Noise, MTF, Slice Thickness, CT dose index, etc.) are described as "Performance Testing - Bench." This typically involves phantom studies or specified calibration procedures rather than patient data.
- For the new software features (AutoPositioning, ExamSplit), testing involved "various cases" and "mock procedure," which are likely internal verification and validation tests rather than tests on a diverse patient dataset.
- Data Provenance: Not explicitly stated as retrospective or prospective patient data, but the descriptions strongly suggest bench testing with phantoms/test objects or internal system validation using mock scenarios/simulated data. No country of origin for patient data is mentioned as no clinical studies with patient data were detailed for the new features.
Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- This information is not provided in the summary. For performance testing on a CT scanner, ground truth is usually established through physical measurements, calibration standards, and technical specifications, rather than expert interpretation of images for diagnosis. For the software features, the "ground truth" was whether the feature performed as designed based on the functional requirements.
Adjudication method (e.g., 2+1, 3+1, none) for the test set:
- None is explicitly mentioned. The testing described (bench tests, functional verification) does not typically involve human adjudication in the way clinical studies for diagnostic accuracy would.
If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
- No MRMC comparative effectiveness study was done or described. The device is a CT imaging system, and while it has a "Low Dose CT Lung Cancer Screening Option," the submission discusses the system's performance and new software features like AutoPositioning and ExamSplit, not a specific AI-assisted diagnostic tool. There is no mention of AI assistance for human readers or any effect size related to reader improvement.
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- The document describes the performance of the CT system and its software features. The "Low Dose CT Lung Cancer Screening Option" is an indication of use for the system, not a separate standalone algorithm whose performance is being evaluated independently. The new features (AutoPositioning, ExamSplit) are functionalities of the CT system itself, not standalone algorithms for diagnosis. The performance testing is focused on the system's technical specifications and the correct functioning of these features. Therefore, this question is not directly applicable in the context of the information provided for this CT device's 510(k).
The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- For image quality and dose metrics (Dose Profile, Noise, MTF, etc.), the ground truth is established by physical measurements, standardized phantoms, and adherence to technical specifications and industry standards.
- For the new software features (AutoPositioning, ExamSplit), the ground truth was the pre-defined functional requirements and expected system behavior.
The sample size for the training set:
- This information is not provided as the document describes a CT imaging system and its software features, not a machine learning or AI model that requires a dedicated training set for diagnostic purposes described in the output. The software features mentioned (AutoPositioning, ExamSplit) are likely rule-based or algorithmic improvements, not deep learning models.
How the ground truth for the training set was established:
- This information is not provided and is not applicable given the absence of a stated training set for a machine learning or AI algorithm.

Scientific Concepts

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.

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.
