MRI SYSTEMS, including ASM-030PIII (OPENMARK III), ASM-040P (OPENMARK 4000) and ASM-050P (OPENMARK 5000), are 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 yield information that may assist in diagnosis.

Device Description

MRI SYSTEMS include a series of open permanent magnet MRI system with magnetic field strength of 0.3T, 0.4T and 0.5T respectively. The model number for each of the corresponding system is ASM-030PIII (OPENMARK III), ASM-040P (OPENMARK 4000) and ASM-050P (OPENMARK 5000) respectively. They are composed of Magnet, Magnet Enclosure, Patient Table, Gradient Coil. RF Transmission Coil. RF Receiver Coil. Client PC, and Imaging Cabinet. The system software, APEX, based on Windows XP® Professional is an interactive program with user friendly interface.

AI/ML Overview

The provided text is a 510(k) summary for MRI SYSTEMS (ASM-030PIII, ASM-040P, ASM-050P). It focuses on demonstrating substantial equivalence to a predicate device through non-clinical testing. It does not contain information about the acceptance criteria or a study proving the device meets specific performance metrics in the way typically required for AI/CADe devices.

Therefore, many of the requested details cannot be extracted from this document.

Here's an attempt to answer based on the provided text, highlighting what is not available:

1. Table of Acceptance Criteria and Reported Device Performance

Not available. The document states "Bench tests were conducted to verify that the proposed device met all design specifications as was Substantially Equivalent (SE) to the predicate device." However, specific acceptance criteria (e.g., sensitivity, specificity, accuracy) for clinical performance and the device's reported performance against such criteria are not provided. The testing focused on compliance with various engineering and safety standards.

Acceptance Criteria	Reported Device Performance
Not specified for clinical performance	Not specified for clinical performance
Compliance with IEC 60601-1, IEC 60601-1-2, IEC 60601-2-33	Met all design specifications and complied with standards.
Compliance with NEMA MS-1-2008 (SNR)	Met design specifications.
Compliance with NEMA MS 2-2008 (Geometric Distortion)	Met design specifications.
Compliance with NEMA MS 3-2008 (Image Uniformity)	Met design specifications.
Compliance with NEMA MS 5-2003 (Slice Thickness)	Met design specifications.

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

Not applicable. The document describes non-clinical bench testing for compliance with standards. It does not involve a clinical test set of patient data.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

Not applicable. No clinical ground truth was established as this was non-clinical bench testing.

4. Adjudication Method for the Test Set

Not applicable. No clinical test set or adjudication process is mentioned.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, If So, What Was the Effect Size of How Much Human Readers Improve with AI vs Without AI Assistance

No. This document describes a traditional MRI system, not an AI or CADe device. Therefore, no MRMC study or AI assistance is relevant.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

Not applicable. This is a medical imaging device, not an algorithm being tested in isolation.

7. The Type of Ground Truth Used

For the non-clinical tests, the "ground truth" was defined by the specifications of the standards (e.g., NEMA standards for SNR, geometric distortion, uniformity, slice thickness). The device's performance was compared against these established technical specifications.

8. The Sample Size for the Training Set

Not applicable. This is a conventional MRI system, not an AI/machine learning device that requires a training set.

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

Not applicable. No training set for an algorithm is involved.

Dear Mr. Mouser:

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.

If your device is classified (see above) into class II (Special Controls), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. 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 Parts 801 and 809); medical device reporting (reporting of

{4}------------------------------------------------

medical device-related adverse events) (21 CFR 803); and good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820). This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed nredicate device results in a classification for your device and thus, permits your device to proceed to the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Parts 801 and 809), please contact the Office of In Vitro Diagnostic Device Evaluation and Safety at (301) 796-5450. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm for the CDRH's Office of Surveillance and Biometrics/Division of Postmarket Surveillance.

You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or (301) 796-7100 or at its Internet address http://www.fda.gov/cdrh/industry/support/index.html.

Regulation Number and Section

§ 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.
