SCENARIA View (K190841)
No
The summary describes standard CT technology and image post-processing techniques (MPR, volume rendering) without mentioning AI or ML. The performance studies focus on image quality and dose, not AI/ML algorithm performance.
No
The device is described as an image acquisition and post-processing system for diagnostic purposes, and for interventional needle guidance; it does not mention directly treating or curing any medical condition.
Yes
The device is a multi-slice computed tomography system used to acquire axial volumes for diagnostic imaging (cross-sectional images of the body) and for lung cancer screening. It also has post-processing capabilities to provide additional information, all of which are indicative of a diagnostic device.
No
The device description explicitly states that the SCENARIA View system is a multi-slice computed tomography system consisting of hardware components such as a Gantry, Operator's Workstation, Patient Table, and High-Frequency X-ray Generator, in addition to software.
Based on the provided text, the SCENARIA View system is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: IVD devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information about a person's health. This testing is done in vitro (outside the body).
- SCENARIA View Function: The SCENARIA View system is a Computed Tomography (CT) system. It uses X-rays to create images of the inside of the body in vivo (within the body). It does not analyze biological specimens.
- Intended Use: The intended use describes acquiring images of the whole body and for interventional needle guidance. This is consistent with an imaging device, not an IVD.
- Device Description: The description details the components of a CT scanner (gantry, X-ray tube, detector, etc.), which are used for imaging the body directly.
Therefore, the SCENARIA View system falls under the category of medical imaging devices, not In Vitro Diagnostic devices.
N/A
Intended Use / Indications for Use
The SCENARIA View system is indicated to acquire axial volumes of the whole body including the head. Images can be acquired in axial, helical, or dynamic modes. The SCENARIA View system can also be used for interventional needle guidance.
Volume datasets acquired by a SCENARIA View system can be post-processed in the SCENARIA View system to provide additional information. Post-processing capabilities of the SCENARIA View software include, multi-planar reconstruction (MPR), and volume rendering.
Volume datasets acquired by a SCENARIA View system can be transferred to external devices via a DICOM standard interface.
The Low Dose CT Lung Cancer Screening Option for the SCENARIA View system is indicated for using low dose CT for lung cancer screening must be conducted with the established program criteria and protocols that have been approved and published by a governmental body, a professional medical society, and/or Hitachi.

Device Description
The SCENARIA View 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 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.
The SCENARIA View 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.

Summary of Performance Studies
A clinical evaluation comparison was conducted with the SCENARIA View system and the SCENARIA Phase 3 System (K150595) and found to be substantially equivalent as documented in Section 10 - Performance.
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 10 - Performance.
The evaluation results confirm the performance characteristics of the SCENARIA View are comparable to the predicate device and support our conclusion that the subject system is substantially equivalent.
Hitachi has conducted a clinical image study to assess the image quality of the images reconstructed by using FBP and the two new features. (HiMAR Plus, Intelli IPV).
