20140152308 | METHOD AND APPARATUS FOR ACQUIRING B1 MAGNETIC FIELD INFORMATION - A method acquires RF magnetic field information (B1 magnetic field information) in response to generated radio frequency (RF) pulses in a magnetic resonance imaging (MRI) system. An RF excitation pulse sequence is generated, and the generated RF excitation pulse sequence includes a plurality of RF excitation pulses individually having different flip angles. The generated RF excitation pulse sequence is transmitted to a target object. RF echo response signals are received from the target object corresponding to the plurality of RF excitation pulses and B1 information is acquired by processing the received RF echo response signals. | 06-05-2014 |
20140152307 | METHOD AND APPARATUS FOR ACQUIRING B1 MAGNETIC FIELD INFORMATION - A system acquires RF magnetic field information (B1 magnetic field information) in response to generated radio frequency (RF) pulses applied to a target object via at least one of a plurality of RF coil elements in a magnetic resonance imaging (MRI) system. The system acquires first information comprising B1 magnetic field phase information of a B1 magnetic field formed by the respective RF coil elements and acquires second information comprising B1 magnetic field phase information of a B1 magnetic field formed by a combination of two or more of a plurality of RF coil elements. The system acquires third information comprising B1 magnetic field phase information by combining the first information and the second information and processes the first, second and third information in providing a B1 map indicating spatial distribution of a B1 magnetic field. | 06-05-2014 |
20140125339 | PHASED ARRAY RF COIL FOR MAGNETIC RESONANCE IMAGING - A phased array radio-frequency (RF) coil includes a cylindrical frame including a coaxial inner frame and a coaxial outer frame having different diameters; and vertical loop coils arranged in a circumferential direction of the cylindrical frame. Each vertical loop coil includes an inner conductor extending in a lengthwise direction on the coaxial inner frame; an outer conductor extending in a lengthwise direction on the coaxial outer frame and facing the inner conductor; and a first resonant frequency adjustment capacitor for connecting one end of the inner conductor in the lengthwise direction and one end of the outer conductor in the lengthwise direction so that the phased array RF coil resonates at an MR operating frequency. | 05-08-2014 |
