发明名称 Apparatus for teaching the structures and projection of arterial systems
摘要 A housing is provided with an observation opening which exposes a three dimensional model of an arterial system. When a rear-lighted projection screen is placed over the observation opening, light from a projector within the housing casts a shadow of the model on the screen to simulate the view seen in arteriography procedures.
