ABSTRACT:
A method and a device for the composition of an MR image with respiration-controlled recording of the spin echoes. The phase coding gradient of an MR equipment is stepped as a function of a motion phase of the respiratory motion once per respiration cycle. With a constant phase coding gradient several scans, possibly EKG-triggered, are then recorded within the respiration cycle. The spin echo signals recorded for each scan are stored in a first memory. In a second memory, the amplitude of the respiratory motion at the respective scan moment is stored. Then a comparison of all stored amplitude of the respiratory motion with a reference value R is made. For the composition of the MR image only that scan per respiration cycle is used for which the respective amplitude of the respiratory motion fulfills a given criterion with respect to the reference value R.
