In which of the following diagrams is the wedge symbol on one or more beams oriented incorrectly? 

Which of the following statements are TRUE regarding IMRT?  NOMOS Peacock was one of the first commercially available Serial Tomotherapy delivery  systems.  IMRT delivers significantly higher integral dose than most traditional 3D/2D planning methods.  IMRT methods increased the awareness of risk associated with “marginal miss”  Isodose lines are usually more conformal to the target structures with IMRT than with VMAT   

True or False: When placing wedges on 2 beams, the toes of the wedges are placed together.

What is the difference in a non-coplanar beam? 

True or False: DIBH and prone are better alternatives than treating patients supine free breathing because it results in both lower heart and lung doses.
