The following problem, arising from medical imaging, is addressed: Suppose that T is a known tetrahedron in ^3 with centroid at the origin. Also known is the orthogonal projection U of the vertices of the image ϕ T of T under an unknown rotation ϕ about the origin. Under what circumstances can ϕ be determined from T and U?
