Intended Use

The Superopen 0.23T(Modified) is intended to produce images that 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 (T), spin-spin relaxation time (T2) and flow. When interpreted by a trained physician, these images provide information that can be useful in determining a diagnosis. The Superopen 0.23T(Modified) is an imaging device, and is intended to provide the physician with the ability to perform magnetic resonance imaging (MRI) 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 (T1), spin-spin relaxation time (T2), and flow. When interpreted by a trained physician, these images provide information that can be useful in diagnosis determination.

Device Story

Superopen 0.23T(Modified) is a 0.35T permanent magnet MRI system; utilizes NdFeB magnet material. System acquires proton magnetic resonance signals; transforms inputs via gradient subsystems (X, Y, Z planes) and RF subsystems for signal transmission/reception. Produces 2D/3D cross-sectional images (transverse, coronal, sagittal, oblique, curved) of head, body, spine, and extremities. Operated by trained clinicians in clinical settings. Console computer with interactive Windows-based interface manages scanning, image reconstruction, and archiving. Physicians interpret images to assist in diagnosis. Benefits include non-invasive diagnostic imaging without ionizing radiation.

Clinical Evidence

No clinical data. Bench testing only.

Technological Characteristics

0.35T permanent magnet MRI system; NdFeB magnet material. Gradient subsystem for X, Y, Z fields; RF subsystem for signal processing. 2D/3D imaging capabilities. Standards: IEC60601-1, IEC60601-2-33, 21 CFR Subchapter J, IEC60825-1, DICOM 3.0, NEMA MS Series (MS1-MS8).

Indications for Use

Indicated for patients requiring non-invasive MRI imaging of the head, body, spine, and extremities. Supports T1, T2, proton density weighted imaging, diffusion weighted imaging, and MR Angiography.

Regulatory Classification

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).

Special Controls

*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.

#### Safety and Effectiveness information

Intended Uses:

The Superopen 0.23T(Modified) is intended to produce images that 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 (T), spin-spin relaxation time (T2) and flow. When interpreted by a trained physician, these images provide information that can be useful in determining a diagnosis.

Device Description:

The Superopen 0.23T(Modified) is a 0.35T permanent magnet MRI system. The magnet is mainly made of NdFeB material. The system software based on Windows (TM) is an interactive program with user-friendly interface. Its functions cover scanning control, image reconstruction and image/archive management and maintenance.

Predicated Device:

K033315 : Superopen 0.23T

Statement of Substantial Equivalence:

The Superopen 0.23T(Modified) is of comparable type and substantially equivalent to the Superopen 0.23T (K033315) in that they are similar in technology and intended uses. It is a modified product based on the Superopen 0.23T. Both of these systems are open-permanent-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 interactive 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.
