Trinias
The Trinias is an angiographic X-ray system, which is used for diagnostic imaging and interventional procedures. The Trinias is intended to be used for cardiac angiography, neurovascular angiography, abdominal angiography, peripheral angiography, rotational angiography, multi-purpose angiography and whole body radiographic/fluoroscopic procedures.
This notification is for a modification is the addition of the new MH-700 (ceiling mounted C-Arm). This is the functional equivalent of previous C-Arm MH-400. All options declared under K203535 remain available. The Lateral Angiographic C-arm Support MH-700 allows examination of a patient by fluoroscopy or radiography from different angles with the patient kept in a horizontal position in combination with a Frontal C-arm Support MH-600, an X-ray high voltage unit, X-ray tube unit, X-ray image recording unit (FPD), digital angiography system, catheterization table, etc. The range of available digital receptor panels remains unchanged from our predicate K203535. For installation, ceiling strength is important because the total weight of MH-700 exceeds 1200 kg. The MH-700 features faster movement speeds as compared to the previous model, the MH-400.

This document is a 510(k) summary for the Shimadzu Trinias angiographic X-ray system. It describes modifications to an existing device and demonstrates substantial equivalence to a predicate device (K123508).
Based on the provided document, the device in question is a medical imaging system (angiographic X-ray system), not an AI/ML-based device. Therefore, the typical acceptance criteria and study designs associated with AI/ML systems (e.g., performance metrics like sensitivity/specificity, multi-reader multi-case studies, ground truth establishment by experts, training/test set provenance) are not applicable here.
The regulatory approval for this device is based on showing substantial equivalence to a previously cleared predicate device, rather than proving performance against specific AI/ML acceptance criteria. The modifications are hardware and software updates to the existing X-ray system.
Here's an analysis of the provided information in the context of device approval, highlighting why AI/ML-specific criteria are not met or relevant:
1. Table of Acceptance Criteria and Reported Device Performance

2. Sample Size Used for the Test Set and Data Provenance
Not Applicable (for AI/ML test set data).
There is no "test set" in the sense of a clinical image dataset used to evaluate an AI algorithm's diagnostic performance. The testing performed was non-clinical bench and standards testing. This involves engineering tests, electrical safety tests, radiation safety compliance tests, and software validation tests.
The data provenance refers to the origin of the device's design, manufacturing, and testing; it does not refer to clinical image data. The manufacturer is Shimadzu Corporation, based in Kyoto, Japan.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
Not Applicable.
No "ground truth" derived from expert interpretation of medical images was established for this submission, as it's not an AI/ML diagnostic aid. The device's performance is validated against engineering specifications, safety standards, and functional requirements.
4. Adjudication Method for the Test Set
Not Applicable.
Since there's no expert interpretation of a test set, there is no adjudication method.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done
No. A MRMC study was not done.
MRMC studies are typically performed for AI/ML diagnostic devices to assess how human reader performance (e.g., radiologists) improves with AI assistance compared to without it. This submission is for an X-ray imaging system itself, not an AI-assisted diagnostic tool.
Therefore, there is no effect size of how human readers improve with AI vs. without AI assistance.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
No.
This concept applies to AI/ML algorithms that can produce an output independently. The Trinias is an imaging system; its "performance" is its ability to acquire images, comply with safety standards, and function as intended.
7. The Type of Ground Truth Used
Compliance with regulated standards and functional specifications.
The "ground truth" for this device's approval lies in its adherence to international safety standards (e.g., IEC 60601 series, IEC 62304 for software) and U.S. performance standards (21 CFR 1020.30, .31, .32), as well as verification of its mechanical and electrical functions. This is demonstrated through "bench and standards testing" and "proper system operation is fully verified upon installation."
8. The Sample Size for the Training Set
Not Applicable.
This refers to training data for AI/ML models. The Trinias is a hardware and software system. While its internal software components undergo development and testing, there isn't a "training set" in the AI/ML sense.
9. How the Ground Truth for the Training Set Was Established
Not Applicable.
As there is no AI/ML training set, there is no ground truth established for it. Software validation (IEC 62304) and adherence to design specifications guide the software development, but this is distinct from training an AI model.
In summary: The provided document is a 510(k) submission for an updated medical imaging hardware system (X-ray). Its approval focuses on demonstrating substantial equivalence to a predicate device through non-clinical performance and safety testing, and compliance with established regulatory standards. It does not involve AI/ML technology or associated clinical performance studies with diagnostic accuracy endpoints.
