The HI STAR system is indicated for use a general purpose MR imager that produces transverse, sagittal, coronal, and oblique cross-sectional images of internal structures of the human body, head, and extremities. Contrast in these images reflect the intrinsic oroperties of the hydrogen proton, proton density, T1, and T2, and the extrinsic parameters of the applied imaging sequences. The indications for the HI STAR do not differ significantly from the predicate, or legally marketed devices.

The Health Images HI STAR is a proton (H-1) Magnetic Resonance Imaging device. The HI STAR has been designed to produce transverse, sagittal, coronal, and oblique section images of the head, body and extremities of the human body. Contrast in these images is produced primarily by T1, T2, and proton density tissue characteristics. This imager employs conventional MRI imaging techniques in which the application of a combination of pulsed radio frequency energy and magnetic gradient fields is applied to the body to generate MR proton echo signals. These multidimensionally coded signals are converted by Fourier transform into 2D and 3D image sets.
