No
The summary describes standard CT technology and image post-processing techniques (MPR, volume rendering) without mentioning AI or ML.
No.
The device is a diagnostic imaging system (CT scanner) used to acquire images for diagnostic purposes, not to provide therapy or treatment.
Yes
The "Intended Use / Indications for Use" states that the system acquires axial volumes and can be used for interventional needle guidance. The "Device Description" states it produces cross-sectional images. The "Summary of Performance Studies" directly states, "Hitachi believes the SCENARIA View is diagnostic and meet the user needs." These indicate the device is used to diagnose or aid in diagnosis.
No
The device description explicitly lists hardware components such as a Gantry, Operator's Workstation, Patient Table, High-Frequency X-ray Generator, and accessories, indicating it is a physical system, not software-only.
Based on the provided information, the SCENARIA View system is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- SCENARIA View Function: The SCENARIA View system is a Computed Tomography (CT) system that uses X-rays to create cross-sectional images of the inside of the human body. It directly interacts with the patient, not with specimens taken from the patient.
- Intended Use: The intended use clearly states it's for acquiring axial volumes of the whole body and for interventional needle guidance. This is consistent with imaging the body directly.
- Device Description: The description details the hardware components (gantry, X-ray tube, detector) and how it produces images from X-ray data collected from the patient.
- Lack of Specimen Handling: There is no mention of handling or analyzing biological specimens.
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
Function
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.
Scientific Concepts
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.
Physical and Performance Characteristics
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 (study type, sample size, AUC, MRMC, standalone performance, key results)
A clinical evaluation comparison was conducted with the SCENARIA View system and the SCENARIA Phase 3 System (K150595) and found to be substantially equivalent.
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. These tests and results support inclusion of the Lung Screening Option on the SCENARIA View.
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 of the head, chest, abdomen, and shoulder that includes an evaluation. In addition, a clinical study was conducted with the Intelli IPV, FBP, and HiMAR features which also includes evaluations. Therefore, based on a thorough analysis and of the clinical images Hitachi believes the SCENARIA View is diagnostic and meet the user needs.

Summary of Clinical Testing
Hitachi has conducted a clinical image study of the head, chest, abdomen, and shoulder that includes an evaluation. In addition, a clinical study was conducted with the Intelli IPV, FBP, and HiMAR features which also includes evaluations. Therefore, based on a thorough analysis and of the clinical images Hitachi believes the SCENARIA View is diagnostic and meet the user needs.
Conclusions
Hitachi believes that, based on the information included in the submission, SCENARIA View Whole-body X-ray CT System is substantially equivalent with respect to hardware, base elements of the software, safety, effectiveness, and functionality to the SCENARIA Phase 3 Whole-Body X-ray CT System (K150595).
