The medical processing system performs the selected enhancement on the subset of data and the enhanced subset is displayed. The enhancement may include performing a single-axis zoom on the subset.

Characterizing states of subject

Among other things, a user of a browser is exposed simultaneously to three interfaces: A viewing interface for at least one image of a subject that is stored on a device on which the browser is running, a decision support interface that aids the user in determining the state of the subject based on the image, and a template interface that aids the user in capturing uniform descriptive information about the state of the subject. At least two of the viewing interface, the decision support interface, and the template interface operate cooperatively so that actions of the user with respect to one of the two interfaces causes changes in content exposed by the other of the two interfaces.
