Claim 17:
18. A non-transitory computer-readable medium embodying a program for image co-registration, said program having instructions executable by a processor for performing a plurality of operations, the operations comprising:
causing an imaging probe to emit energy, and responsively and dynamically acquire images, the acquired images having a given dimensionality;
detecting a phase of a body cycle associated with the acquired images;
selecting a currently acquired image, repeatedly and dynamically with said acquiring, from among the acquired images and, as a result of said selecting, changing, repeatedly and dynamically, membership in a set of images of said dimensionality, wherein the membership in the set of images is based, at least in part, on the detected phase of the body cycle;
determining an image quality metric for at least some of the acquired images, the image quality metric comprising at least one of an entropy, an image gradient, or an image intensity;
calculating a measure of spatial proximity between the currently acquired image and an image in said set, said selecting being based on the calculated measure and the image quality metric; and,
synchronously with the change, dynamically and iteratively registering said set to an image having a dimensionality higher than said given dimensionality,
wherein said changing includes replacing an existing member of the set of images with the selected currently acquired image based at least in part on the measure of spatial proximity and the image quality metric; and
wherein the image having the dimensionality higher than said given dimensionality is associated with the phase of the body cycle.
