Abstract
In order to provide an RF coil for effective imaging from a vertex to an upper T spine, a coil surrounding a forehead portion of an imaging object, a coil surrounding a nose portion over the protuberance of the nose, a coil surrounding the neck, and a coil holding the upper T spine, are integrally molded to construct a coil assembly which can be separated into front and rear parts.
Claims17
An RF coil comprising:
- a first coil loop surrounding a head of an imaging object approximately in a forehead and upper portions, said first coil loop being divisible along a forward/backward direction of the imaging object;
- a second coil loop surrounding the head of the imaging object and having a projecting portion which surrounds a nose portion thereof, said second coil loop being divisible along the forward/backward direction of the imaging object;
- and
- a third coil loop surrounding a neck or the imaging object, said third coil loop being divisible along the forward/backward direction of the imaging object, said first, second and third coil loops being separate from each other.
