Method of quick back projection for computed tomography and improved CT machine employing the method

摘要: Computer tomography employs quick back projection, allowing for example software based projection in a minicomputer. From the line of sight absorption data which is normally taken computed tomography, apparatus generates additional files more limited resolution, most resolution file has such that controlled employed minicomputer can be completed period time one minute or less. Thereafter, operator controls cursor so subsequent on higher employ only subset available to also limit processing time.
