Abstract
A method of imaging, by means of magnetic resonance, at least a portion of a human or animal subject of interest () positioned in a static magnetic field, the method comprising: —taking measurements of electrocardiogram data; —generate vector cardiogram data from the electrocardiogram data; —determining at least one parameter of an acquisition period of acquiring magnetic resonance signals from the vector cardiogram data in order to synchronize measurement of magnetic resonance signals to a cyclic movement of the heart of the subject of interest (); wherein the at least one parameter of the acquisition period is determined from an actual value of a discriminating function and a predetermined reference function, wherein for determining the at least one parameter of the acquisition period, a step of adapting at least one of the discriminating function and the predetermined reference function is executed, dependent on a breathing status of the human or animal subject of interest (); and—a magnetic resonance imaging system () for acquisition of images of at least a portion of a human or animal subject of interest (), synchronized to a cyclic movement of the heart of the subject of interest (), comprising: —a control unit () for controlling functions of the magnetic resonance imaging system (); —an image processing unit () provided for processing acquired magnetic resonance signals; —an electrocardiogram device () for taking measurements of electrocardiogram data of the heart of the subject of interest (); —a synchronization unit () coupled to the electrocardiogram device () and configured for determining at least one parameter of an acquisition period from the vector cardiogram data, wherein the synchronization unit () is configured to provide trigger signals () indicative of the determined at least one parameter of the acquisition period to the control unit (); and wherein the synchronization unit () is configured to adapt at least one of the discriminating function and the predetermined reference function, dependent on a breathing status of the human or animal subject of interest ().
