Session Title: How will IEC Standards Updates Affect the Practice of Medical Physics?
Question 1: 1. Which is a key benefit of IEC International Standards?
Choice A:Enable new laws to regulate sale of electrical equipment
Choice B:Generate revenue for member states
Choice C:Facilitate international trade and market relevance of products
Choice D:Ensure the highest possible technical performance
Choice E:Eliminate requirements for testing new products
Question 2: The role of the Technical Advisory Group (TAG) is which of the following?
Choice A:Publish new International Standards
Choice B:Pass regulations regarding new equipment
Choice C:Attend Subcommittee meeting and cast votes
Choice D:Submit comments and votes to the Working Group
Choice E:Advise the National Committee how to vote
Question 3: How do IEC safety standards improve safety in radiology and radiation therapy?
Choice A:They impose requirements on manufacturers for design and testing of new equipment models
Choice B:They recommend education and training for professionals working with the equipment
Choice C:They contain regulations that countries must comply with, to be able to offer radiology and radiation oncology services
Choice D:They provide guidance for local regulatory authorities to conduct inspections of clinical facilities
Choice E:All of the above
Question 4: Setting reasonable action limits on Deviation Index (defined in IEC standard 62494-1 Ed. 1) to determine if repeat radiographic imaging is required is:

J., Uzenoff, R. and Willis, C. (2018), Current state of practice regarding digital radiography exposure indicators and deviation indices: Report of AAPM Imaging Physics Committee Task Group 232. Med. Phys., 45: e1146-e1160. doi:10.1002/mp.13212
Choice A:Achievable and applicable across all x-ray acquisition protocols and practices
Choice B:Achievable using the same target exposure index for all x-ray acquisition protocols
Choice C:Achievable using a practice, equipment, and x-ray protocol dependent approach
Choice D:Not achievable at all
Question 5: Use of a threshold value of reference point air kerma (Ka,r) as defined in IEC Standard 60601-2-43 Ed. 2 as a metric for follow up of image guided interventions is
Reference:B. C. Perry, C. R. Ingraham, B. K. Stewart, K. Valji and K. M. Kanal, Academic radiology 26 (2), 163-169 (2019).
Choice A:Not as useful as using a fluoroscopy time threshold
Choice B:Useful to identify patients who may have tissue reactions
Choice C:Consistent with Society of Interventional Radiology guidelines
Choice D:Both answers B and C
Question 6: IEC standard 60601-2-44 Ed. 3 Amendment 1(Basic safety and essential performance of CT scanners) approximates CTDI100 for detector configurations (nT) > 40mm by (PLEASE NOTE PARANTHESIS USED INSTEAD OF SUBSCRIPTS FOR EASE OF READING):

Choice A:Using the same formula as for detector configurations < 40mm
Choice B:Utilizing the ratio of CTDI(free air, nT>40mm) to CTDI(free air, nt<40mm)
Choice C:Utilizing the ratio of CTDI(w, nt>40mm) to CTDI(w, nt<40mm)
Choice D:Utilizing the ratio of CTDI(free air, nT<40mm) to CTDI(free air, nt>40mm)
