## Abstract

The simulation system (100) and method for simulating virtual human-body dissection, as compared to prior-arts, provides an accurate representation of human anatomical structures, allowing users to perform virtual dissections and gain tactile insights into the texture and feel of various organs, tissues and structures. Simulation system (100) includes a computing bed (10) with an interactive-display screen (20), a haptic device (30), a graphic rendering device (40), a control unit (50) and processing unit (51). The interactive-display screen (20) enables selection of a region-selection module (20a), a tool-selection module (20b), an anatomical planes and positions module (20c) and a training module (20d) which are operated and viewed by the haptic device (30), a graphic rendering device (40) to perform virtual dissections and gain tactile insights into the texture and feel.
