Abstract: PROBLEM TO BE SOLVED: To easily perform the regulating work of resonance frequency at a low cost by mounting a socket or connector on a coil conductor, and attachably and detachably mounting a capacitor board having a capacitor thereon on the socket or connector. SOLUTION: An RF coil for MRI 100 comprises to coil conductor 1 having the fixed capacitor 2, and the socket 3 provided on a part of the coil conductor 1. The capacitor board 10 having a fixed capacitor 11 thereon is mounted on the coil conductor 1 attachable to and detachable from the socket 3. The used fixed capacitor 2 shares the fixed portion of the resonance frequency, and the fixed capacitor 11 is provided in order to share the variable portion of the resonance frequency, The socket 3 has a number of pins raised thereon, and the pins are inserted to a number of holes of the capacitor board 10. whereby the coil conductor 1 is electrically connected to the capacitor 11.

Abstract: A helmet-like medical diagnostic apparatus that is fixed or worn has motorized gimbals that automatically swivel to positions around a patient's head. An end effector extends radially from the gimbals toward the head to place a coil or other directional sensor snugly against the scalp. A coil sensor can be part of a sensitive circuit to measure eddy currents within the brain. Accelerometers, or other tilt-measuring gauges, on the sensor determine the precise 3D orientation of the sensor when resting against the head. The orientation can compensate coil measurements, find an exact spot again, or map opposing sides of the patient's cranium, even with a fidgeting unconscious patient. The head can be scanned in its entirety, or a spot scan may be prompted from other diagnostic data.

Abstract: A helmet-like medical diagnostic apparatus that is fixed or worn has motorized gimbals that automatically swivel to positions around a patient's head. An end effector extends radially from the gimbals toward the head to place a coil or other directional sensor snugly against the scalp. A coil sensor can be part of a sensitive circuit to measure eddy currents within the brain. Accelerometers, or other tilt-measuring gauges, are compared between those on the sensor and those on the apparatus's base to determine the precise 3D orientation of the sensor when resting against the head. The orientation can compensate coil measurements, find an exact spot again, or map opposing sides of the patient's cranium, even with a fidgeting unconscious patient. The head can be scanned in its entirety, or a spot scan may be prompted from other diagnostic data.
