Figure  2-1:  Lateral  and  AP  acquisitions  of  X-ray  fluoroscopic  images  of  the  pelvis phantom.
Figure  2-3:  CT-derived  DRR  images  produced  by  the  ray-casting  algorithm not  accessed  in  an  optimal  way
Figure  2-4:  CT-derived  DRR  images  produced  by  the  voxel-projection  algorithm The  main  idea  behind  the  latter  comes  from  the  field  of  computer  graphics,  and is  referred  to  as  view-based  rendering
Figure  2-5:  The  transformation  parameter  T  which  relates  the  coordinate  frames  of the  imaging  environment  and  the  data  volume;  T  =  D,  o R o  Dd.
