The ECHELON Oval MRI 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.
