摘要:
A method for magnetic resonance imaging of a part of a human body arranged in a steady magnetic field. The part of the body to be imaged may contain, for example a coronary artery in the vicinity of the heart. Other feasible parts are, for example joints or the cruciate ligaments. To this end, two MR images are made of the coronary artery extending between the first imaging plane and the second imaging plane of the first and the second MR image, respectively, a first cross section of the coronary artery being reproduced in the first MR image whereas a second cross section of the coronary artery is reproduced in the second MR image. Subsequently, a third imaging plane for a third MR image is determined by an operator who determines two points by indicating, in the first and the second image, points of intersection of the first and the second cross section of the coronary artery in the first and the second imaging plane. The adjusting parameters for forming a third MR image of the third imaging plane are subsequently calculated on the basis of these points of intersection and a third point that can be chosen at liberty. The third MR image then largely reproduces the coronary artery, except when the coronary artery is strongly curved.
