摘要
The invention provides for a magnetic resonance imaging system (100) comprising: a magnet (104) for generating a main magnetic field with an imaging zone (110) and a gradient coil system (110 112). The gradient coil system comprises a set of unshielded gradient coils (110). The magnetic resonance imaging system further comprises a processor (130) for controlling the magnetic resonance imaging system. Execution of the instructions stored in a memory cause the processor to: acquire (200 304) imaging magnetic resonance data (152) from a volume (109) within the imaging zone using a zero echo time pulse sequence; reconstruct (202 306) a three dimensional image (156) using the imaging magnetic resonance data; subtract a calibration image from the three dimensional image the calibration image having been acquired without a subject in the imaging zone; and render the three dimensional image on a display by projecting it on a two dimensional plane.
