Intended Use

The Supria 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 is a multi-slice computed tomography system designed to perform multi-slice CT scanning supported by 16-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 system uses 16-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 16 slices of data simultaneously. The Xray 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 system consists of a Gantry, Operator's Workstation, Patient Table, High-Frequency X-ray Generator, and accessories.

AI/ML Overview

The provided text is a 510(k) Pre-market Notification for a medical device, specifically the HITACHI Supria Whole-body X-ray CT System Phase 3. It compares the new device to a predicate device (HITACHI SUPRIA w/guideShot Option K161748) to demonstrate substantial equivalence, rather than providing a detailed study proving the device meets acceptance criteria in the sense of a performance study with specific metrics and statistical analysis.

The document states that the new device has two new features: "Intelli IP Quick" (a faster noise reduction technique) and "HiMAR" (reduces artifacts caused by metal). The "Performance Testing - Clinical" section briefly mentions that "clinical images were collected and analyzed" for these new features to "ensure that images constructed by the Supria Whole-body X-ray CT System meet user needs." It also notes that "Hitachi has provided clinical images demonstrating the image quality of Intelli IP Quick and HiMAR features and validated by a physician."

Therefore, it is important to note that the provided text does NOT contain the detailed information typically found in a clinical study report that defines and proves specific acceptance criteria for performance metrics (like sensitivity, specificity, accuracy) using a rigorous methodology. Instead, it relies on demonstrating comparable performance to a predicate device and physician validation of image quality for new features.

Based on the provided text, here's what can be extracted and what remains unknown:


Acceptance Criteria and Device Performance (Based on provided text)

Since direct quantitative acceptance criteria and performance metrics are not explicitly stated in a table format for the new features or overall device, we can infer the "acceptance" is primarily based on substantial equivalence to the predicate device and subjective physician validation of image quality for the new features.

Acceptance Criterion (Inferred from 510(k) context)Reported Device Performance (From text)
Overall substantial equivalence to predicate device (SUPRIA w/guideShot Option K161748) in terms of:"The analysis confirms the performance characteristics of the Supria Whole-body X-ray CT System Phase 3 are comparable to the predicate device and support our conclusion that the Phase 3 system is substantially equivalent." "Hitachi believes that, based on the information included in the submission, Supria Whole-body X-ray CT System Phase 3 is substantially equivalent with respect to hardware, base elements of the software, safety, effectiveness, and functionality to the SUPRIA w/guideShot Option (K161748)."
- HardwareNo differences identified (e.g., Gantry, Detector, X-ray Tube, X-ray Generator, Patient Table, Display, Image Storage parameters are identical to predicate).
- Base elements of softwareMost software features are identical to the predicate. Key differences (Intelli IP Quick, HiMAR, Orbit synchronization scan, Off-time mode, On-time standby, Shutter Scan Reduction) are described as improvements or additional functionalities.
- Safety"The technological characteristics do not impact safety and effectiveness." (Stated for the differences in Table 3). Compliance with applicable safety standards (e.g., IEC 60601 series, NEMA XR 25, NEMA XR26) is declared.
- Effectiveness"The technological characteristics do not impact safety and effectiveness." (Stated for the differences in Table 3). Clinical images demonstrating the image quality of Intelli IP Quick and HiMAR features were "collected and analyzed" and "validated by a physician" to "ensure that images constructed by the Supria Whole-body X-ray CT System meet user needs." The overall "Performance Comparison" section also states "A clinical evaluation comparison was conducted with the Supria Phase 3 system and the SUPRIA w/guideShot Option (K161748) and found to be substantially equivalent."
- FunctionalityDetailed comparison in Table 2 shows identical functionality for many parameters, with new features (Intelli IP Quick, HiMAR etc.) presented as enhancements that do not negatively impact core functionality.
Image Quality with new features (Intelli IP Quick, HiMAR)"clinical images demonstrating the image quality of Intelli IP Quick and HiMAR features and validated by a physician." The images were collected and analyzed "to ensure that images constructed by the Supria Whole-body X-ray CT System meet user needs."

Study Details:

  1. Sample sizes used for the test set and data provenance:

    • Test Set Sample Size: Not specified. The document only mentions that "clinical images were collected and analyzed" for the new features. No specific number of images or patients is provided.
    • Data Provenance: Not specified regarding country of origin. The study is described as "clinical images were collected," implying real patient data. It is a retrospective or prospective study is not specified, but the phrasing "were collected" could suggest a collection from existing or newly acquired cases.
  2. Number of experts used to establish the ground truth for the test set and their qualifications:

    • Number of Experts: Not specified. The document states the image quality was "validated by a physician." It does not specify if this was one physician or a panel.
    • Qualifications of Experts: The qualification is generally stated as "a physician." Specific specialties (e.g., Radiologist) or years of experience are not mentioned.
  3. Adjudication method for the test set:

    • Not specified. Given the limited detail ("validated by a physician"), it's unlikely a formal adjudication method (like 2+1 or 3+1) was employed and documented in this 510(k) submission.
  4. If a multi-reader multi-case (MRMC) comparative effectiveness study was done:

    • Not explicitly stated or described. The document refers to a "clinical evaluation comparison" but does not detail it as a formal MRMC study. It states the comparison "found to be substantially equivalent" and that clinical images were "validated by a physician." There is no mention of multiple human readers, a comparative effectiveness study design, or an effect size for human readers' improvement with AI assistance. The new features (Intelli IP Quick, HiMAR) are signal processing techniques within the CT system, not an AI assistance tool for human interpretation in the sense of a CAD system.
  5. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:

    • The "performance comparison" section mentions "Performance Testing - Bench" with a rationale analysis indicating "Hitachi judged that Supria Whole-body X-ray CT System Phase 3 is substantially equivalent to the predicate." It also notes that the 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." This sounds like standalone technical performance testing, but not necessarily a clinical "algorithm only" performance evaluation akin to an AI diagnostic tool. The device itself is a CT scanner, not an AI algorithm intended for standalone diagnosis.
  6. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

    • For the clinical evaluation of the new features (Intelli IP Quick, HiMAR), the ground truth appears to be based on "physician validation" of "image quality" and ensuring that the images "meet user needs." This is a subjective assessment, not pathology or outcomes data. For the comparison to the predicate, it's about comparable physical and performance characteristics.
  7. The sample size for the training set:

    • Not applicable / Not specified. The document describes a CT system and its new image processing features. It does not mention a "training set" in the context of machine learning. The "Intelli IP Quick" and "HiMAR" are described as "processing techniques" that reduce noise or reduce metal artifacts, implying algorithms that might have been developed and tuned, but the text does not detail any "training data" or "training set" as would be seen for a deep learning model.
  8. How the ground truth for the training set was established:

    • Not applicable / Not specified. As no training set or machine learning model is explicitly described, there is no information on how a ground truth for such a set would have been established.

Device Description

Function

The Supria is a multi-slice computed tomography system designed to perform multi-slice CT scanning supported by 16-detector technology. The system allows optimum clinical applications ranging from routine exams in response to the diversified circumstances in imaging whole body regions.

{5}------------------------------------------------

Scientific Concepts

The Supria system uses 16-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 16 slices of data simultaneously. The Xray 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 Supria 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

A clinical evaluation comparison was conducted with the Supria Phase 3 system and the SUPRIA w/guideShot Option (K161748) and found to be substantially equivalent.

There is no change in the performance of the system in regards to Dose Profile, Noise, Mean CT number and Uniformity, Spatial Resolution, Tomographic Section Thickness and Sensitivity Profile, Tomographic Plane Location, and CT dose index.

A rationale analysis was then conducted and the results are contained in Table 1.

The differences from the predicate device to Supria Whole-body X-ray CT System Phase 3 are explained in Table 3.

Table 3 Analysis of Differences

Features
01Intelli IP Quick: Intelli IP Quick is a faster noise reduction processing technique as compared to Intelli IP.
02HIMAR: HIMAR reduces lack of photon caused by X-ray going through a highly absorptive body such as metals and ametal artifact caused by beam hardening.
03Orbit synchronization scan: By using the orbit synchronization, the orbit of the volume scan multiple sequences canbe combined and differences can be easily extracted by comparing each image together.
04Off-time mode: The power consumption of the detector system is saved and noise is reduced when the power of theCT system is off. According to the usage of the system, the starting time can be registered.
05On-time standby: During operation of the CT system, The power consumption under the standby condition is savedand noise is reduced.
06Shutter Scan Reduction: The number of shutter scans was reduced.

Therefore, based on a thorough analysis and comparison of the Supria Whole-body X-ray CT System Phase 3 and the predicate device, the technological characteristics do not impact safety and effectiveness.
