Abstract

---

Quality imaging has always been the prerequisite for successful Radiation Therapy (RT) as regards patient positioning and tumor localization. As RT is a multi-step process involving treatment planning and delivery over many sessions, potential errors at different stages can compromise treatment accuracy and precision. Image verification with IGRT is therefore critical for the effective delivery of RT especially in the era of Intensity Modulated Radiation Therapy (IMRT), Volumetric Arc Therapy (VMAT) and Stereotactic Radiosurgery/Radiation Therapy (SRS/SRT) where complex tumors are treated dose escalation and steep dose gradient. The geometric challenges encountered with tumors and organs that move during or between RT sessions further add to the need for IGRT to improve the therapeutic ratio of better tumor control with reduced side effects from RT.
