Patent ID: 10330758

Abstract:
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.
