A diagnosis assisting apparatus, method, and program include calculating a first index value representing a direction and magnitude of motion of each portion of the heart for a three-dimensional anatomical image at a given phase of a three-dimensional anatomical image group representing a heart at each phase with respect to a further phase, calculating a second index value that serves as a diagnostic indicator of each portion of the heart from the three-dimensional anatomical image at the given phase or the three-dimensional anatomical image group, generating a two-dimensional image of the entire heart in which the second index value of each portion of the heart is disposed in a planar fashion, and displaying a mark representing the first index value superimposed on the generated two-dimensional image in a manner that allows the direction of motion of the first index value to be visually recognized.

A tutorial or diagnostic aid based on the representation and iterative interpretation of visual images is taught. A teaching or diagnostic session is created by overlaying an interpretation layer via a software application onto the visual image layer and synchronizing the two with the time code of the visual image. The interpretation layer allows the reviewer to identify image areas of interest by gesture and append comments thereto in real time; i.e. images or portions of images within the visual representation playback may be identified and labeled and have the concurrent commentary associated therewith. The comments are indexed and linked to a database of similar topics. The flow of the session is recorded to show the images, deictic gestures associated therewith, and commentary associated with the gestures, to enable subsequent users to playback a session and follow the flow of thought (i.e. image identification and commentary within the original session). Iterative sessions allow additional image identification and commentary to be accomplished. Additional database access through the index may further enhance a teaching session, or provide for research sessions and report generation.
