Abstract:
1. A system for performing a simulated medical procedure, comprising: (a) a simulated organ; (b) a simulated instrument for performing the simulated medical procedure on said simulated organ; (c) a locator for determining a location of said simulated instrument within said simulated organ; and (d) a visual display for displaying images according to said location of said simulated instrument within said simulated organ for providing visual feedback, such that said images simulate actual visual data received during an actual medical procedure as performed on an actual subject, said visual display including: (i) a three-dimensional mathematical model for modeling said simulated organ according to a corresponding actual organ, said model being divided into a plurality of segments, said plurality of segments being arranged in a linear sequence; (ii) a loader for selecting at least one of said plurality of segments from said linear sequence for rendering, said at least one of said plurality of segments being selected according to said location of said simulated instrument within said simulated organ; (iii) a controller for rendering a simulated image from said segment according to said location of said simulated instrument; (iv) a bleeding model for simulating a presence of blood in said simulated image wherein said blood is simulated and rendered according to said bleeding model, and wherein said rendered blood is added to said rendered simulated image wherein said bleeding model simulates bleeding caused by a pathological condition simulated for said simulated organ and bleeding caused by an action with said simulated instrument; and (iv) a displayer for displaying said rendered simulated image.
