Nuclear magnetic resonance apparatus for diagnostic examination

Anordnung zur Übertragung von Magnetresonanzsignalen

pi /2 power divider

Combined positron emission tomography and magnetic resonance tomography (PET/MRT) assembly

Combined positron-emission tomography and magnetic-resonance tomography apparatus, has conductors of stripline antenna device formed as screening sleeves impermeable to high frequency radiation

Ultrasonic object imaging method and device with optic signal transmission

Method of operation of ultrasound diagnostic apparatus involves monitoring of applicator handpiece is in use and otherwise reducing power requirement

Electroacoustic system for reproduction of acoustic signals within MR diagnosis equipment, has a loudspeaker with an electrodynamic vibration system that is designed taking into account the tomograph static base magnetic field

SURFACE RESONATOR FOR NUCLEAR SPIN TOMOGRAPHY

Magnetic resonance diagnostic system operating method in which a working region is defined for each applied high frequency pulse within the examination volume and pulses are individually matched to a determined field distribution
