1. A method of processing an acquired image of a body portion intended to receive a treatment associated with a tool, the body portion including a first zone of interest to receive the treatment, the method comprising the steps of: receiving an instruction to indicate a second zone interest of the imaged anatomy to avoid impact associated with the treatment; calculating a first set of image elements of the acquired image associated with a first part of a circulatory network in communication to supply the first zone of interest and not in communication to supply the second zone of interest; calculating a second set of image elements of the acquired image associated with a second part of the circulatory network in communication to supply the second zone of interest; and creating a display that differentiates the second set of image elements associated with the second part of the circulatory network from a remainder of the acquired image.
