The document describes standard MRI technology and image processing, but there is no mention of AI or ML in the intended use, device description, or performance studies. The "Mentions AI, DNN, or ML" section explicitly states "Not Found".
No
The device is described as an "imaging device" and its purpose is to provide "physiological and clinical information" and images that can be "useful in diagnosis determination." It is an MRI system, which is used for diagnostic imaging, not for treating conditions.
Yes
The "Intended Use / Indications for Use" section explicitly states that the images produced by the MRI system, "When interpreted by a trained physician, provide information that can be useful in diagnosis determination." This indicates that the device assists in the diagnostic process.
No
The device description explicitly states it is a "0.23T permanent magnet MRI system" composed of various hardware components like a magnet, gradient coils, RF coils, etc., in addition to software.
Based on the provided information, the Superopen 0.23T is not an IVD (In Vitro Diagnostic) device.
Here's why:
- IVD devices are used to examine specimens taken from the human body. The description clearly states that the Superopen 0.23T is an "imaging device" that obtains information "non-invasively". It produces images of the internal structure of the body without taking any samples.
- The intended use is for imaging and providing physiological and clinical information through the analysis of magnetic resonance properties. This is a characteristic of medical imaging devices, not IVD devices.
- The device description details the components of an MRI system. This further confirms its nature as an imaging device.
Therefore, the Superopen 0.23T falls under the category of medical imaging devices, not In Vitro Diagnostic devices.
N/A
Intended Use / Indications for Use
The Superopen 0.23T is an imaging device, and is intended to provide the physician with physiological and clinical information obtained non-invasively and without the use of ionizing radiation. The MRI system produces transverse, coronal, sagittal, oblique, and curved cross-sectional images that display the internal structure of the head, body, or extremities. The images produced by MRI system reflect the spatial distribution of protons (hydrogen nuclei) exhibiting magnetic resonance. The NMR properties that determine the image appearance are proton density, spin-lattice relaxation time (Ti), spin-spin relaxation time (T2), and flow. When interpreted by a trained physician, these images provide information that can be useful in diagnosis determination.
The indications for use are as follows:
Anatomical Region: Head, Neck, Shoulder, Breast, Wrist, Ankle, Body, Spine, Knee, Extremities
Nucleus excited: Proton
Diagnostic uses: T1,T2, proton density weighted imaging Diffusion weighted imaging MR Angiography

§ 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.

The Superopen 0.23T (modified) system used the same materials, construction and operating principle as our existing marketed product, Superopen 0.23T MRI system (K062860) and Superstar 0.35T(K071154)
Predicated Device:
K062860: Superopen 0.23T K071154: Superstar 0.35T Statement of Substantial Equivalence:
The Superopen 0.23T (modified) system is the upgrade version of Superopen 0.23T MRI system(K062860). It is comparable and substantially equivalent to the Superopen 0.23T MRI system and Superstar 0.35T(K071154) in that they are similar in technology and intended uses. Both of these systems are open-magnet MR Imaging System, use Gradient Subsystem to provide controlled and uniform gradient magnet fields in the X, Y and Z planes, and use RF Subsystem to complete the function of RF signal transmitting/receiving and processing. Image reconstruction is controlled by console's computer that has an interfactive user interface, and the system produces 2D and 3D image that can be filmed or electronically stored for future review. Both of these systems have the traditional MRI unit.
- a. Non-clinical test: The device has been evaluated for performance, biocompatibility and effectiveness as well as electrical, mechanical, chemical , biocompatibility safety and has been found to substantially equivalent to Superopen 0.23T and Superstar 0.35T.
- b. Clinical test: No clinical test conducted.
Conclusion: The device was evaluated against Superopen 0.23T (K062860) and Superstar 0.35T(K071154) for all performance, safety & effectiveness requirements. According to the comparison based on the requirements of 21.CFR 807.87, we state that these devices are substantially equivalent.

Dear Mr. Borsai:
This letter corrects our substantially equivalent letter of September 9, 2008.
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 (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 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
3
CFR Part 807); labeling (21 CFR Part 801); 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.
This letter will allow you to continue 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 predicate 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 Part 801), please contact the Office of Compliance at (240) 276-0120. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). 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 (240) 276-3150 or at its Internet address http://www.fda.gov/cdrh/dsma/dsmamain.html
