  • Method for avoiding over-convolutions in the phase coding direction in nuclear magnetic resonance tomography
    Patent number: 6747451
    Abstract: In a method and magnetic tomography apparatus wherein over-convolutions in the phase coding direction in magnetic resonance tomography are avoided, orthogonal slices are measured as overview presentations (localizers) in a first step and slices for the following measurement series are then determined. Overlapping phases and the magnitude of the appertaining signal are calculated and a warning is emitted when this over-convoluted signal exceeds a reference value. A selection possibility is then offered for reducing the phase coding steps and enlarging the field of view and, if selected, the phase coding step width is automatically reduced.
