Session Title: Adaptive Radiotherapy
Question 1: Anatomical changes which may vary highly day to day and which vary highly within the typical time course of a single fraction (minutes to hours) are best managed with which type of adaptive radiation therapy workflow?

Choice A:Offline
Choice B:Online
Choice C:Realtime
Choice D:Any of A, B, or C are appropriate
Question 2: Which of the following most appropriately lists the set of core enabling technologies of online adaptive radiation therapy?
Reference:Green, Olga L., Lauren E. Henke, and Geoffrey D. Hugo. "Practical clinical workflows for online and offline adaptive radiation therapy." Seminars in radiation oncology. Vol. 29. No. 3. 2019.
Choice A:Anatomical imaging, Functional imaging, Replanning tools
Choice B:Anatomical imaging, Decision support tools, Replanning tools

Choice D:Anatomical imaging, Deformable image registration, Replanning tools
Question 3: True or False: Functional adaption can be applied to both target and normal tissues.
Reference:Matuszak MM, Kashani R, Green M, Owen D, Jolly S, Mierzwa M, Functional Adaptation in Radiation Therapy, Seminars in Radiation Oncology 2019, 29 (3), Pages 236-244.
Choice A:True
Choice B:False
Question 4: Which of the following is the most clear example of a functional adaptation in radiation therapy?
Reference:Matuszak MM, Kashani R, Green M, Owen D, Jolly S, Mierzwa M, Functional Adaptation in Radiation Therapy, Seminars in Radiation Oncology 2019, 29 (3), Pages 236-244
Choice A:Obtaining pre-treatment PET imaging
Choice B:Minimizing mean dose to normal lung in treatment planning
Choice C:Changing a prostate plan mid-treatment due to differences in bladder filling
Choice D:Updating the tumor prescription based on the difference between mid- and pre-treatment diffusion weighted MRI in head/neck
Question 5: Failure mode and effects analysis (FMEA) indicates that offline adaptive radiotherapy:
Reference:Noel CE, Santanam L, Parikh PJ, Mutic S. Process-based quality management for clinical implementation of adaptive radiotherapy. Med Phys. 2014;41 (8Part1):081717.
Choice A:has lower risk priority numbers (PRN) than the standard planning
Choice B:introduces unique new critical failures
Choice C:has the same critical failures as the standard planning
Choice D:has equal risk priority numbers as the standard planning
Question 6: Which of the following are the key components of the workflow of adaptive radiotherapy
