Intended Use
The uMR Omega system is indicated for use as a magnetic resonance diagnostic device (MRDD) that produces sagittal, transverse, coronal, and oblique cross sectional images, and spectroscopic images, and that display internal anatomical structure and/or function of the head, body and extremities. These images and the physical parameters derived from the images when interpreted by a trained physician yield information that may assist the diagnosis. Contrast agents may be used depending on the region of interest of the scan.
Device Story
uMR Omega is a 3.0T superconducting MRI system with a 75cm bore. It acquires MR signals via RF coils and gradient coils, processed by a spectrometer and computer system. Modifications include a new RF power amplifier (uXD2201), additional RF coils (Tx/Rx Knee Coil-24, SuperFlex Body Wide-24), new VSM models, and a dockable patient table. It incorporates a camera-based 'uVision' positioning workflow and a Resoundant acoustic driver for MRE. New software features include 4D Flow Quantification, MRE, SNAP, CEST, T1Rho, and FSP+. Used in clinical settings by trained physicians/technicians. Output consists of anatomical and functional MR images and derived physical parameters. These outputs assist physicians in diagnostic decision-making, potentially improving diagnostic accuracy and patient comfort through advanced imaging sequences and streamlined positioning.
Clinical Evidence
Bench testing only. Performance evaluation reports provided for new features including 4D Flow (gre_fq), MRE (epi_se_mre), CEST (fse_mx), T1rho (gre, fse_mx), mPLD ASL, and silica gel imaging. Compliance with electrical safety (ES 60601-1), EMC (IEC 60601-1-2), and MR safety (IEC 60601-2-33) standards confirmed. Biocompatibility testing (ISO 10993-5, 10993-10) demonstrated no cytotoxicity, irritation, or sensitization.
Technological Characteristics
3.0T superconducting magnet; 75cm bore; 45mT/m gradient amplitude; 200T/m/s slew rate; 2 transmit channels; up to 96 receive channels. Materials tested per ISO 10993. Connectivity via DICOM/NEMA standards. Software includes pulse sequence control and image processing algorithms. Sterilization not applicable (non-invasive).
Indications for Use
Indicated for use as a magnetic resonance diagnostic device (MRDD) to produce cross-sectional images and spectroscopic images of the head, body, and extremities to display internal anatomical structure and/or function. Used by trained physicians to assist in diagnosis. Contrast agents may be used.
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.

Dear Xin Gao:
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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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
