Airis II Magnetic Resonance Diagnostic Device,Interventional MR Package

By providing in-suite scan control and viewing of MR images, the AIRIS II with the Interventional MR Package aids in the performance of minimally invasive, diagnostic, and therapeutic procedures of the head, body and extremities which may be facilitated by real-time MR guidance. Such procedures must be performed with MRI-compatible instrumentation, as selected and evaluated by the clinical user.

The MR system 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 MR 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 the MR 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.
