Abstract
Abstract A medical investigative system in which a person interacts with the system to interject information that is utilized by the system to establish non-restricted environmental modeling of the realities of surrogate conditions to be encountered with invasive or semi-invasive procedures. This is accomplished by video display of simulated internal conditions that appear life-like, as well as by display of monitor data including, for example, blood pressure, respiration, heart beat rate and the like.
