Intended Use

Elixbo PM545 is indicated for use as magnetic resonance diagnostic device that produces axial, sagittal, coronal and oblique cross sectional images, and that displays the anatomical and pathological information of the head, body, or extremities. When interpreted by a trained physician, these images yield information that can be useful in determining a diagnosis.

Device Description

The proposed device, Elixbo PM545, is a Magnetic Resonance Imaging System that utilizes a 0.45 Tesla permanent magnet in an open gantry design. It's indicated for use as magnetic resonance diagnostic devices (MRDD) that produce transverse, sagittal, coronal and oblique cross sectional images, and that display the internal structure and/or function of the head, body, or extremities. These images when interpreted by a trained physician vield information that may assist in diagnosis. The MRI system is composed of magnet, gradient & shimming system, RF system, spectrometer, temperature controller, patient table system, isolation transformer, respiratory gating unit, chiller and control system. The system software, Prospect, based on Windows® XP professional operating system is an interactive program with user friendly interface. The proposed device includes twelve receiving coils which are Head Coil, Neck Coil, Knee Coil, Shoulder Coil, Wrist Coil, Breast Coil, Ankle Coil, Body Coil (14"), Body Coil (17"), Body Coil (20"), General Purpose Coil (6"), and General Purpose Coil (9").

AI/ML Overview

The provided document describes the safety and effectiveness information for the Elixbo PM545 Magnetic Resonance Imaging System, submitted as a 510(k) premarket notification. This submission indicates that the device's performance was evaluated through non-clinical bench tests and a comparison to a predicate device, rather than a clinical study with specific acceptance criteria for diagnostic performance metrics like sensitivity or specificity.

1. Table of Acceptance Criteria and Reported Device Performance:

The acceptance criteria for the Elixbo PM545 are primarily based on compliance with international standards for medical electrical equipment and a determination of substantial equivalence (SE) to a legally marketed predicate device (mStar MPF4500, K073457). The "device performance" in this context refers to its ability to meet these technical standards and operate comparably to the predicate device.

2. Sample Size Used for the Test Set and Data Provenance:

The document describes non-clinical bench tests and a comparison to a predicate device. It does not mention a traditional clinical test set involving human subjects or patient data to evaluate diagnostic performance metrics like sensitivity, specificity, or accuracy. The "test results" refer to engineering and performance tests to demonstrate compliance with standards and equivalence to the predicate. Therefore, information on sample size and data provenance (country of origin, retrospective/prospective) for a clinical test set is not provided because such a study was not presented.

3. Number of Experts Used to Establish Ground Truth and Qualifications:

No information is provided regarding experts or ground truth establishment for a diagnostic performance study, as the submission relies on bench testing and comparison to a predicate device.

4. Adjudication Method for the Test Set:

Not applicable, as no external adjudication method for a clinical test set is described.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:

No MRMC study was performed or described in this submission. The device approval relies on substantial equivalence to an existing device, which typically does not require a comparative effectiveness study showing improvement with AI assistance.

6. Standalone Performance Study:

No standalone (algorithm only without human-in-the-loop performance) study for diagnostic performance was conducted or described. The device is a Magnetic Resonance Imaging System, where the human physician is always "in the loop" for interpretation. The "performance" described relates to technical specifications meeting safety and imaging standards.

7. Type of Ground Truth Used:

No "ground truth" (expert consensus, pathology, outcomes data) as typically understood for diagnostic device performance evaluation was used in this 510(k) submission. The "truth" for the evaluation was based on compliance with established technical standards (IEC, NEMA, ISO) and demonstrating that the device's technical specifications and intended use were substantially equivalent to the predicate device.

8. Sample Size for the Training Set:

Not applicable. The document describes a traditional MRI device and its regulatory submission, not an AI/ML-based device that would typically involve a "training set" of data.

9. How the Ground Truth for the Training Set Was Established:

Not applicable, as there is no mention of a training set or ground truth for such a set in this submission.

Dear Mr. Devine:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting (reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

§ 892.1000 Magnetic resonance diagnostic device.

(a)
Identification. A magnetic resonance diagnostic device is intended for general diagnostic use to present images which reflect the spatial distribution and/or magnetic resonance spectra which reflect frequency and distribution of nuclei exhibiting nuclear magnetic resonance. Other physical parameters derived from the images and/or spectra may also be produced. The device includes hydrogen-1 (proton) imaging, sodium-23 imaging, hydrogen-1 spectroscopy, phosphorus-31 spectroscopy, and chemical shift imaging (preserving simultaneous frequency and spatial information).(b)
Classification. Class II (special controls). A magnetic resonance imaging disposable kit intended for use with a magnetic resonance diagnostic device only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.
