    • There is disclosed a method of positioning an interventional device in a body using a guide (17) pivoting about a pivot point, comprising locating the spatial coordinates of a target (12) and the pivot point, determining a third point (34) outside of the body lying along or proximate a line (30) extending through the target and pivot point, and aligning the axis of the guide with the third point (34) using an imaging system. There is also disclosed a medical imaging system including a processing unit and computer software operative on the processing unit to permit an operator of the system to locate the spatial coordinates of a target point (12) and a pivot point of a guide (17), and determine a third point (34) outside of the body lying along or proximate a line (30) extending through the target and pivot point. This medical imaging system may further include computer software operative on the processing unit to assist an operator in obtaining an image by which the axis of the guide can be aligned with the third point (34) using an imaging system. There is also disclosed an article of manufacture comprising a computer program encoded in a carrier, wherein the program is operative on a processing unit of a medical imaging system to permit an operator of the system to locate the spatial coordinates of a target point (12) and a pivot point of a guide (17), and determine a third point (34) outside of the body lying along or proximate a line (30) extending through the target (12) and pivot point.

    • There is described method and apparatus for supporting a patient's body (24) in a MR scanner, including supporting it to rotate about its longitudinal axis (22) and cant about a point (46) on the longitudinal axis (42). Also provided are method and apparatus for supporting a patient's head and neck and using a surgical head-holder (34). Yet another embodiment of the invention provides method and apparatus for attaching first and second stirrups (52) to a member (50) supporting the patient. According to yet another embodiment, the invention provides for keeping two or more different members (61, 62) for supporting a patient's body during a medical procedure conducted in conjunction with an MR scanner, wherein each member (61, 62) is adapted to be detachably inserted into a bore (12) of the MR scanner, and wherein each member (61, 62) provides for a different patient support functionality, selecting one of the different members (61, 62) for use in a medical procedure, positioning a patient's body on the selected member, and engaging the member with the MR scanner such that the member is disposed at least in part in a bore (12) of the scanner.
