(57) : The present disclosure generally relates to an automated method and system for generating a panoramic visualization IN of a coronary arterial tree of a subject. The method comprises: acquiring an image volume of a thoracic cavity of the subject, the im - age volume providing a three-dimensional (3D) representation of the thoracic cavity; isolating a coronary structure in the 3D repres - N entation by abating one or more other anatomical structures in the thoracic cavity; abating one or more portions of the coronary 0 structure in the 3D representation that attenuate visualization of the coronary arterial tree; generating, by maximum intensity projec - tion (MIP), a plurality of MIP images of the coronary structure from the 3D representation; and compositing the MIP images to gen - .,. erate the panoramic visualization of the coronary arterial tree.
