Abstract: A method and system for the identification and treatment of events for synchronization and combined display of information in a sequence of frames relating to the progress of a diagnostic investigation or surgery performed on a patient. Frames are searched for the occurrence of an event, the search carried out by comparison between identified events and sought-after events, the latter stored in an archive; in the event of recognition of an event, executing a computer program for carrying out a treatment on the frame and/or the activation of a program procedure for signaling the occurrence of the event; memorizing the event or the frame that contains it, in the correct temporal reference with respect to the sequence of frames.
