Intended Use

iMRX is an integrated imaging system combining X-ray Angiography and Magnetic Resonance for interventional, diagnostic, and intra-operative imaging. The iMRX system uses the Artis zee family of dedicated angiography systems for single and biplane diagnostic imaging and interventional procedures including, but not limited to, pediatric and obese patients. Procedures that can be performed with the iMRX system include cardiac angiography, neuro-angiography, general angiography, rotational angiography, operating room angiography and whole body radiographic/fluoroscopic procedures. The iMRX system can also support the acquisition of position triggered imaging for spatial data synthesis. The iMRX system uses the IMRIS family of Intra-operative MRI systems indicated for use as a magnetic resonance diagnostic device (MRDD) that produce transverse, sagittal, coronal and oblique cross sectional images, spectroscopic images and / or spectra, and that display the internal structure and / or function of the head and whole body. Depending on the region of interest, contrast agents may be used. These images and i or spectra when interpreted by a trained physician yield information that may assist in diagnosis. The iMRX system may also be used for imaging during intra-operative and interventional procedures when performed with MR safe devices or MR conditional devices approved for use with the MR scanner. The iMRX system may also be used for imaging in a multi-room suite.

Device Story

iMRX integrates Siemens Artis zee X-ray angiography system with IMRIS intra-operative MRI system; enables combined imaging in OR or angio suite. MRI unit suspended on overhead rail system for multi-room mobility; operates in RF-shielded environment. Inputs: X-ray signals and MR signals. Outputs: cross-sectional images (transverse, sagittal, coronal, oblique), spectroscopic images/spectra. Used by physicians for intra-operative/interventional guidance; supports spatial data synthesis via position-triggered imaging. Benefits: allows real-time diagnostic imaging during surgery/intervention without patient transport. System retains full diagnostic functionality of standard MRI and angiography systems.

Clinical Evidence

No clinical data. Bench testing only to verify equivalence to Siemens Artis zee and IMRIS Neuro systems regarding safety, imaging performance (signal-to-noise, uniformity, geometric distortion, spatial resolution), and mechanical/electrical hazards.

Technological Characteristics

Integrated system: Siemens Artis zee (X-ray) and IMRIS Neuro (MRI). Overhead rail-mounted MRI system for multi-room use. Includes Magnet Mover Assembly, OR patient table, intra-operative coils, head fixation device. RF-shielded room required. Connectivity: standard diagnostic imaging interfaces. Sterilization: N/A (device is imaging equipment).

Indications for Use

Indicated for head and whole body imaging in pediatric and adult patients, including obese patients. Used for interventional, diagnostic, and intra-operative procedures, including cardiac, neuro, and general angiography, and radiographic/fluoroscopic procedures. Contraindicated for use with non-MR safe or non-MR conditional devices during MRI operation.

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.

#### 4. DEVICE DESCRIPTION

The iMRX system is an integrated configuration combining X-ray Angiography and Magnetic Resonance for interventional, diagnostic, and intra-operative imaging. The iMRX system is the integration of a Siemens Artis zee family (biplane or floor mounted single plane) and the IMRISheuro System (Neuro III-SV or Neuro II-SE system). The iMRX system is a solution providing MRI scanning capabilities in the Angiography room while retaining all the functionality of Siemens Artis zee system. The iMRX system includes a traditional MRI unit that has been suspended on an overhead rail system, and is designed to operate inside an RF shielded room to facilitate imaging in multiple rooms. It provides imaging to support intra-operative and interventional capability in the operating room and angio room, while retaining all diagnostic functionality of a standard MRI system in the diagnostic room.

### 6. SAFETY & EFFECTIVENESS

The iMRX has been designed to provide MRI imaging in an intra-operative setting in the same manner as the predicate IMRISneuro (Neuro II-SE) Systems and to provide a complete range of angiography applications in the same manner as the predicate Siemens Arts zee system.

The iMRX system retains all Siemens Artis zee system safety features including visual and audible warnings. To minimize electrical, mechanical and radiation hazards, IMRIS adheres to recognized and established industry practice, and all equipment complies with standard performance testing. Testing has been combleted to verify the equivalence of iMRX to the Siemens Artis zee system. This assures that the performance of this device can be considered safe and effective with respect to the currently available Siemens Artis zee system.

The iMRX intra-operative features, including Siemens MRI system, Magnet Mover Assembly, OR Patient Table, Intra-operative Coils and Head Fixation Device are substantially equivalent to the same intra-operative features of the predicate Neuro III-SV and predicate Neuro II-SE. The iMRX does not raise any new safety or effectiveness issues related to the use of a moving MRI system in an intra-operative setting.

The iMRX MRI imaging system's software and hardware are substantially equivalent to the Neuro III-SV (based on the Siemens MAGNETOM Verio 3T MRI) System and the Neuro II-SE (based on the Siemens MAGNETOM Espree MRI) system. The iMRX does not raise any new safety issues related to static magnetic field effects, changing magnetic field effects, RF heating or acoustic noise or effectiveness issues related to specification volume, signal to noise, image uniformity, and geometric distortion, slice profile, thickness and gap, or high contrast spatial resolution. Testing has been completed to verify the equivalence of iMRX to the IMRISneuro (Neuro III-SV/Neuro II-SE) system. This assures that the performance of this device can be considered safe and effective with respect to the currently available IMRISneuro system.
