Localization of aorta and left atrium from magnetic resonance imaging

摘要

The aorta and left atrium are localized from magnetic resonance data. The locations of the aorta and left atrium are detected jointly. The aorta and the left atrium are, at least in part, treated as one object. The detection may be from data representing a two-dimensional region. The two-dimensional region may be determined by first detecting the left ventricle from data representing a volume.

主权项

1. A method for localization of the aorta and left atrium from magnetic resonance data, the method comprising:
acquiring a plurality of frames of the magnetic resonance data representing a plurality, respectively, of first planes through a heart of a patient; reconstructing a volume of the heart with the frames of the magnetic resonance data; detecting a position of a left ventricle from the magnetic resonance data of the reconstructed volume; identifying a second plane through the heart and the corresponding magnetic resonance data based on the position of the left ventricle; detecting, jointly and two-dimensionally with a processor, the aorta and the left atrium from the magnetic resonance data for the second plane; and displaying an image as a function of the detecting of the aorta and left atrium.
