Document Summary
Multiplanar reformation: takes raw data and slices it to have it in a bunch of different planes (acquiring images in different planes) You may have to change the protocol if there is a prosthetic because it could cause streaking. 1917 math equation discovered for reconstructing cross- sectional images from transmission measurements. First tomography imaging (lacked sufficient detail to be diagnostic) Hit a road(cid:271)lo(cid:272)k, was(cid:374)"t a(cid:271)le to pro(cid:272)ess a(cid:374)y of the i(cid:374)fo. The beatles signed with electric & music industries (emi), generated money that they reinvested in their company, including the work of one of their engineers (hounsfield), Emi produced the first commercially available ct scanner. First head scan from head whole body scanning first cat scanner developed. Fast scanning of single slices spiral/helical ct arrives. 2006: helical: more in the shape of a spring and not hitting the pt right on (like axial), table is moving throughout entire scan, axial: when xrays are on, the table is stationary.
