Less time on the table for the patient- faster put-through, if trauma, they can diagnose pts sooner, less side effects, less reoccurrence (cid:862)drr(cid:863): digitally reconstructed radiographs. 1917 math equation discovered for reconstructing cross-sectional images from. 1920s first tomography imaging (lacked sufficient detail to be diagnostic) Hit a (cid:396)oad(cid:271)lo(cid:272)k, (cid:449)as(cid:374)"t a(cid:271)le to p(cid:396)o(cid:272)ess a(cid:374)(cid:455) of the i(cid:374)fo.
