CLOCKWISE FROM TOP LEFT FEBRUARY 2015 In turning Potter’s cadaver into a “visible human,” Spitzer and research assistant Jim Heath (at right), apply a coat of polyvinyl alcohol to protect her skin from freezer burn and to provide contrast between the tissue and surrounding material. JANUARY 2017 Lab manager Rachel Klaus (at left) and Spitzer remove the titanium rod from Pot- ter’s hip to prevent it from damaging the cutting blade.
