Solenoid CoilInfoSheet: - Coils - 
Intro,

 - Coils -
 
A coil of wire wound in the form of a long cylinder. When a current is passed through the coil, the magnetic field within the coil is relatively uniform. Solenoid RF coils are commonly used when the static magnetic field is perpendicular to the long axis of the body.
The reason against a solenoidal coil is that the signal is missed when the axis of the solenoidal coil is coaxial with the horizontal magnetic field Bo. If the coil's axis can be put near a right angle (60° to 90°) with the principal field, so the loss in the signal is greatly dismissed, and good SNR can be achieved.
The two forms are single turn solenoid and multiple turn solenoids.

in October of 2004, the company changed the product name of the Stand-Up™ MRI to the Upright™ MRI. The Indomitable™, Upright™ MRI is the only open MRI in the world that can perform positional MRI (pMRI), i.e. the Upright MRI™ scans patients in upright, weight-bearing positions, in addition to the conventional lie-down positions. The Upright™ MRI is the only device that can scan patients in the position their symptoms occur, in their position of pain. In early clinical reports independently confirm the effectiveness and potential of positional MRI. In October 2000, Fonar received permission to market the Indomitable™ from the FDA.
