MULTI-ZONE RADIO-FREQUENCY COIL ARRAY FOR VARIABLE PATIENT SIZES

摘要

A local magnetic resonance (MR) radio frequency (RF) coil (12, 70, 90) includes a fixed size coil housing (19, 72) with an internal opening (26) which receives a portion of a subject anatomy for imaging. The internal opening (26) includes a narrowed portion (28) and a divergent portion (30) which accommodates variable sizes of subject anatomy. A first size of antenna (84) is disposed in the housing (19, 72) adjacent the narrowed portion (28) of the opening and at least a second size of antenna (86) larger than the at least first sized antenna (84) adjacent the divergent portion of the opening.
