摘要： In a method and magnetic resonance tomography apparatus for spatially resolved measurement of the magnetic high frequency field distribution in the apparatus, a double echo high frequency pulse sequence with a first excitation pulse following by at least two refocusing pulses are emitted for generation of a first echo and a following second echo. At least the excitation pulse is slice selective. In an excitation layer defined by the slice selective excitation pulse a first echo image and second echo image are spatially resolved by using suitable gradient pulses for phase or frequency encoding Using the relationships of the amplitudes of the first and second echo image in the various locations the flip angles representing the field strength at the relevant locations in the relevant slice are determined.

摘要： In a magnetic resonance tomography method and apparatus for avoiding peripheral interference signals in magnetic resonance tomography when using spin-echo sequences, the average frequency and the bandwidth of the radio-frequency excitation pulse differ from the average frequency and the bandwidth of the radio-frequency refocusing pulse(s), and the amplitude of the slice selection gradients activated during the radio-frequency excitation pulse differing from the amplitude of the slice selection gradient(s) activated during the radio-frequency refocusing pulse, such that the excitation slice of the RF excitation pulse and the refocusing slice of the RF refocusing pulse(s) in the homogeneous volume (FOV) of the basic magnetic field are superimposed, while the excitation slice of the RF refocusing pulse(s) in the non-homogeneous volume of the basic magnetic field are separated locally, and an echo signal is thereby prevented in the non-homogeneous volume.

摘要： The present invention concerns a method and an apparatus for phase-calibrating an MRI pulse sequence which is used to calculate a linear phase and a constant phase to perform phase calibration on the scanned data, wherein a corresponding pre-scan without a phase encoding gradient is performed before a diagnostic scan. A reference echo is selected from the echoes obtained in the pre-scan. On the basis of the reference echo the constant phase is calculated to be used in performing the phase calibration in the scan. The constant phase that is obtained is correct and not affected by phase jumping. A further image reconstruction performed on the phase-calibrated data produces clear and artifact-free images.

摘要： In a method for avoiding image occlusions in nuclear magnetic resonance tomography apparatus that are operated with multi-echo sequences, at a time t.sub.0, a cross-magnetization in spins is generated in an examination subject with an excitation radio-frequency pulse. At times t.sub.1, t.sub.3, t.sub.5 . . . , at least two refocusing radio-frequency pulses that re-phase the cross-magnetization follow and read-out intervals follow at times t.sub.2, t.sub.4, t.sub.6 . . . The following condition is satisfied in at least one direction for the gradients G activated during the pulse sequence: ##EQU1## Even given quadratic gradient terms, thus, no phase difference occurs between a primary and a stimulated echo path. The presence of such a phase difference causes an image occlusion, and thus such occlusions are avoided by eliminating such a phase difference.

摘要： In a method for adjustment of the field strength of radio-frequency pulses as well as a magnetic resonance measurement system, radio-frequency pulses are emitted by a radio-frequency antenna of a magnetic resonance measurement system in a magnetic resonance measurement. A test volume slice is initially excited by emission of radio-frequency pulses with a defined pulse amplitude by the appertaining radio-frequency antenna and one-dimensional, spatially-resolved characteristic values are determined along an extent direction of the test volume slice. The one-dimensional, spatially-resolved characteristic values respectively represent a local field strength of the B1 field in strips of the test volume slice running perpendicular to the extent direction. An average value of the determined characteristic values is then formed over at least over one determined segment along the extent direction of the test volume slice. A pulse amplitude of the radio-frequency pulses that is to be set for the magnetic resonance measurement to be implemented is determined on the basis of the average value.
