DESCRIPTION:The problem to be solved in this project is to dev
 ise and test an improved method for measuring sour
 ce and detector positions in an RTT system. The RT
 T  is a fixed gantry x-ray computed tomography sca
 nner. The current method for geometry calibration 
 has certain limitations\, principally that it can 
 only derive variations in the XY plane (Z directio
 n is the direction of travel through the machine) 
 and the test object needs to be scanned multiple t
 imes. \n\nThe idea is for the student to design a 
 test piece that when scanned and analysed allows f
 or accurate source and detector position estimates
 \, and then to prove that the approach works by si
 mulation. \n
