Device description
The Wrist Array coils are a phased array design to be used vertically at the patient’s side or horizontally
overhead on the GE MR system. The wrist array comes with two rigid base plates (for flat or curved
tabletops) for fixation to reduce patient motion. The coil receives magnetic resonance signals generated
in hydrogen nuclei (protons) in the wrist while blocking the high-frequency magnetic field applied by the
MRI scanner at specified timings. Images are typically generated as axial, sagittal, coronal oblique slices
and include coverage of the wrist anatomy.
Indications for use
The 1.5T 8ch Wrist Coil is intended to be used in conjunction with a GE 1.5T Magnetic Resonance
Scanner to produce diagnostic images of the wrist anatomy that can be interpreted by a trained
physician.
The 3.0T 8ch Wrist Coil is intended to be used in conjunction with a GE 3.0T Magnetic Resonance Scanner
to produce diagnostic images of the wrist anatomy that can be interpreted by a trained physician.
