Abstract: A head coil for magnetic resonance imaging may be shortened longitudinally to provide for better access by a patient. Extension of the coil may be performed after the positioning of the patient's head significantly simplifying patient positioning with respect to the coil. A portion of a conductor support sliding over the patient's head removable to allow endotracheal tubes or the like to remain undisturbed.

Abstract: An MRI array coil system for neurovascular and spine imaging of a human includes a neck coil having a split top; a dome-like head coil having a dome region, the head coil being slidable between a closed position adjacent to the neck coil and an open position spaced away from the neck coil; a posterior torso coil attached to the neck coil; and an anterior torso coil adapted to cooperate with the posterior coil.

Abstract: An adjustable holder for a magnetic resonance imaging RF surface coil for imaging a part of the body such as the temporomandibular joint. Elements are provided for positioning and securing the RF surface coil at a first predetermined point along a longitudinal axis of the holder and for positioning and securing the RF surface coil at a second predetermined point transverse to the longitudinal axis and at a radial distance R from the longitudinal axis. The preferred embodiment provides orbital movement of the surface coil about the longitudinal axis using a pair of U-shaped runner guides disposed substantially transverse to the longitudinal axis and adjustable clamps in cooperative engagement with the runner guides. The surface coil may be adjusted along a path transverse to the longitudinal axis by way of an adjustable shaft or arm which can be moved inwardly and outwardly, and the surface coil can be pivoted in a step-wise manner using a pivot head having a plurality of equally spaced detents.
