Abstract
In a magnetic resonance tomography pulse sequence, a slice perpendicular to the spatial direction of an inhomogeneity in the static field is first excited. The nuclear spins are re-phased and spin echo signals are readout under a gradient in a second direction. A phase-encoding gradient is activated between the excitation and the readout of the nuclear spins. A predetermined inhomogeneity in the static magnetic field is permanently present and acts during the overall pulse sequence as a permanent magnetic field gradient. With this pulse sequence, an inhomogeneity in two spatial directions can be allowed, which simplifies the construction of a magnet considerably and improves the access to the subject under examination.
