A method of designing a coil or set of coils to achieve a coil with minimum or substantially minimum inductance to produce a desired magnetic field.

Electrical coils

A hyperthermia applicator/MRI probe assembly for hyperthermia treatment of a subject. The assembly includes a hyperthermia applicator for heating target regions of a subject and a MRI probe which is utilized to monitor temperatures within the heating region. The hyperthermia applicator and MRI probe are coupled to a control system which receives information from the MRI probe and utilizes the information to control the hyperthermia applicator so as to maintain constant, desired temperatures within the heating region. The hyperthermia applicator/MRI probe assembly of the present invention allows for temperature control within about 0.5.degree. C.

A compact local gradient coil is combined with a local RF coil to provide lower powered, higher strength gradient fields and faster gradient response as is useful in magnetic resonance imaging. Interference between the RF coil and gradient coil is minimized by placement of the gradient coil external to the RF coil and by gradient coils that are axially symmetric and/or have conductors substantially orthogonal to the RF coil conductors. Acoustic noise in these smaller, stronger coils is reduced with ports cut into the coil forms.

An ammunition conveyor is equipped to accommodate projectiles and propellant in alternating carrier positions. Conveyor cross members or rungs carry retainers to engage the projectile and propellant canister bodies and provide lateral restraint preserving their vertical orientations in the carrier positions. The rungs also carry vertical restraints which project out into engaging relation with the projectiles and propellant canisters to preclude hazardous vertical movements during field transport of the magazine. The vertical restraints are structured to automatically accommodate projectiles and propellant canisters of different length dimensions.
