Claim 0:
1. A method for visually assisting an operator of an ultrasound system, comprising:
receiving a first imaging data of a first anatomical region using a first coordinate system, the first imaging data marked with a landmark for identifying the first anatomical region;
transforming the first imaging data of the first anatomical region from the first coordinate system to a cylindrical coordinate system, wherein the first coordinate system is different from the cylindrical coordinate system;
displaying a live ultrasound image of a second anatomical region as received from an ultrasound transducer;
receiving positional information for the ultrasound transducer corresponding to an alignment line of the second anatomical region, the alignment line being a user selected line of the second anatomical region corresponding to the landmark in the first anatomical region, and the positional information being a roll angle of the ultrasound transducer corresponding to the alignment line; and
wherein, the landmark and the positional information for the ultrasound transducer corresponding to the alignment line of the second anatomical region are for aligning the first imaging data to the live ultrasound image;
displaying a transformed image from the transformed first imaging data of the first anatomical region corresponding to the alignment line, and the transformed image includes the landmark;
wherein the transformed image and the live ultrasound image are displayed simultaneously;
overlaying indicia on the transformed image indicating the roll angle of the ultrasound transducer, wherein the indicia changes in response to a change in the roll angle of the ultrasound transducer.
