A system and method for visually assisting an operator of an ultrasound system are provided. In an aspect, the method involves receiving imaging data of an anatomical region using a first coordinate system, the imaging data marked with a landmark for identifying the anatomical region； transforming the imaging data of the anatomical region from the coordinate system to a cylindrical coordinate system； displaying a live ultrasound image of the anatomical region as received from an ultrasound transducer； receiving positional information from the ultrasound transducer corresponding to an alignment point of the anatomical region； and displaying a transformed image from the transformed imaging data of the anatomical region corresponding to the alignment point using the landmark； wherein the transformed image and the live ultrasound image are displayed simultaneously. In another aspect, the method involves generating and transforming a 3D model of the first anatomical regions.
