APPARATUS AND METHODS FOR REDUCING VISIBILITY OF A PERIPHERY OF AN IMAGE STREAM

摘要

Apparatus and methods are described for imaging a portion of a body of a subject that undergoes a motion cycle, including acquiring a plurality of image frames of the portion of the subject's body. A given feature is identified in at least some of the image frames. At least some image frames are image tracked with respect to the feature, and the image frames that have been image tracked with respect to the given feature are displayed as a stream of image frames. Visibility of a periphery of the displayed stream of image frames is at least partially reduced. Other applications are also described.
