The virtual anatomy, ready for dissection

In a basement lab at NYU Langone Medical Center in Manhattan last month, students in scrubs and surgical gloves hovered over cadavers on gurneys, preparing, as would-be doctors have for centuries, to separate rib cages and examine organs. But the dead are imperfect stand-ins for the living. Death—and embalming fluid—take a toll. So, in an adjacent classroom, a group of students wearing 3-D glasses made by Nvidia, a graphics processing firm, dissected a virtual cadaver projected on a screen.
