Abstract
The present invention provides systems, methods, and devices for imaging an internal anatomical structure. Ultrasound image data of the anatomical structure is acquired within a first coordinate system, and graphical data (e.g., sites of interest) is acquired in a second coordinate system. The location of an ultrasound transducer within the first coordinate system and a second coordinate system is determined, and a transformation between the first and second coordinate systems is then performed based on the location of the ultrasound transducer within the first and second coordinate systems. Using this transformation, the ultrasound image data, which has previously been acquired in the first coordinate system, can be registered and displayed within the second coordinate system, along with graphical data. Or the graphical data, which has previously been acquired in the second coordinate system, can be registered and displayed within the first coordinate system, along with the image data. In this manner, the image and graphical data can be easily displayed together independent of any movement by the imaging device that acquires the image data.
