I. Introduction Image-guided radiation therapy (IGRT) can be defined as a radiation therapy procedure  that utilizes patient imaging information (x-ray, CT, MRI, PET, etc.) to aid in accurately  delivering treatment to the patient’s target site.  By this definition, all current modes of  radiation therapy could be considered IGRT.  There is, however, a more commonly used  meaning for IGRT as it pertains to current treatment techniques.  In the present context,  IGRT refers to radiotherapy that uses image guidance procedures for target localization  just prior to and during treatment.  By imaging the patient before and during treatment,  errors due to inter- and intra-fractional variations in the patient’s setup and anatomy can  be minimized. As radiation therapy treatment technologies become more conformal (3D-CRT and  IMRT), the need for accurate and current imaging information becomes ever greater.  A  number of IGRT-enabling technologies have been developed that are accessible in the  treatment room or mounted directly on the linear accelerator.  For this lab, the in-room  computed tomography scanner (CT on the rail) was reviewed and will be discussed in  this report.  An in-room CT scanner is a conventional CT scanner that is placed on rails inside the
