No
The summary describes standard CT imaging and post-processing techniques (CTA, MPR, volume rendering) without mentioning AI or ML.
No.
The device is an X-ray Computed Tomography system used for imaging and diagnosis, not for treating diseases or conditions.
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."
No
The device description clearly states it is a "multi-slice computed tomography system" and mentions hardware components like "64-detector technology." While it includes software for post-processing, it is fundamentally a hardware-based imaging system.
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 perform tests on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The Supria True64 System is an X-ray Computed Tomography (CT) system. It uses X-rays to create images of the inside of the body. This is an in vivo imaging technique, meaning it is performed on a living organism, not on samples taken from the body.
- Intended Use: The intended use clearly states it is for "head, whole body, and vascular X-ray Computed Tomography applications." This involves imaging the patient directly.
Therefore, the Supria True64 System falls under the category of medical imaging devices, not In Vitro Diagnostics.
N/A
Intended Use / Indications for Use
The Supria True64 System is indicated for head, whole body, and vascular X-ray Computed Tomography applications in patients of all ages. The images can be acquired in either axial, helical, or dynamic modes. The volume datasets acquired by the Supria can be post processed by the system to provide additional information. Post processing capabilities included in the Supria software include CT angiography (CTA), Multi-planar reconstruction (MPR) and volume rendering. Volume datasets acquired by the Supria 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 Supria True64 is a multi-slice computed tomography system designed to perform multi-slice CT scanning supported by 64-detector technology. The system allows optimum clinical applications ranging from routine exams in response to the diversified circumstances in imaging whole body regions.
The Supria True64 system uses 64-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 Supria True64 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)
Validation Testing - Bench: Based on the results of the ECG Prospective Scan Performance Testing Report contained in Verification and Validation Documentation of Section 9, Hitachi judged that Supria True64 with ECG Prospective Scan (Axial) performs to specifications.
Validation Testing - Clinical: None required.
The analysis confirms the performance characteristics of the Supria True64 are comparable to the predicate device and support our conclusion that the subject system is substantially equivalent to Supria True64 Whole-body X-ray CT System (K171738).
This device complies with all applicable requirements for Dose Profile, Noise, Mean CT number and Uniformity, Spatial Resolution, Tomographic Section Thickness and Sensitivity Profile, Tomographic Plane Location, and CT dose index. Adding the ECG Prospective Scan (Axial) would not impact the results of the testing done in the original submission.
Noise, Mean CT number, Uniformity and Spatial Resolution test results for the Supria True64 Whole-body X-ray CT System (K171738) would not be effected by this feature.
the ECG Prospective Scan feature was subject to performance tests, which confirmed that the X-ray was in synchronization with the ECG trigger and the acquired images. The results confirmed that images which are synchronized with ECG R-wave signal can be acquired by using ECG Prospective Scan.

ECG Prospective Axial Scan feature was originally cleared on the HITACHI SCENARIA Wholebody X-ray CT System (K101888).
Therefore, based on a thorough analysis and comparison of subject device (Supria True64) and the predicate device, the technological characteristics do not impact safety and effectiveness.
Substantial Equivalence

Therefore, based on a thorough analysis and comparison of the functions, scientific concepts. physical and performance characteristics, performance comparison and technological characteristics, the proposed Supria True64 Whole-body X-ray CT System is considered substantially equivalent to the currently marketed predicate device (Supria True64 Whole-body X-ray CT System (K171738)) in terms of design features, fundamental scientific technology, indications for use, and safety and effectiveness.

Summary of Non-Clinical Testing
This device complies with all applicable requirements for Dose Profile. Noise. Mean CT number and Uniformity, Spatial Resolution, Tomographic Section Thickness and Sensitivity Profile, Tomographic Plane Location, and CT dose index. Adding the ECG Prospective Scan (Axial) would not impact the results of the testing done in the original submission.
Noise, Mean CT number, Uniformity and Spatial Resolution test results for the Supria True64 Whole-body X-ray CT System (K171738) would not be effected by this feature.
In addition, the Supria True64 system is in conformance with the applicable parts of the following standards:

In addition, the ECG Prospective Scan feature was subject to performance tests, which confirmed that the X-ray was in synchronization with the ECG trigger and the acquired images. The results confirmed that images which are synchronized with ECG R-wave signal can be acquired by using ECG Prospective Scan.
Summary of Clinical Testing
Based on verification and validation results and analysis of the additional feature, Hitachi believes clinical testing was not required.
Conclusions
The results of the performance testing, the validation and the electromagnetic compatibility electrical safety testing demonstrate that the proposed Supria True64 Whole-body X-ray CT System with ECG Prospective Axial Scan meets the acceptance criteria and is adequate for its intended use.
In addition, the risk analysis demonstrate that all risks are sufficiently mitigated, that no new risks are introduced, and the overall residual risks are acceptable.
Based on the supporting data provided in this submission, the proposed Supria True64 Wholebody X-ray CT System with ECG Prospective Axial Scan is considered substantially equivalent to the predicate device in terms of safety and effectiveness. There are no significant differences that may raise new issues of safety or effectiveness. Bench tests and user validation have been
