Q45 = b

Q46 = a

Have looked around the web and come up with these answers -- anyone know if this is right?!

Think the 1st Q is right but not sure about the CT Q -- anyone have any thoughts? Cheers

Yeah, me too!

Think Q45 is right but have found it hard to get any info on different doses from CT scanners.

Are there any CT experts out there who can help?

Q45. is correct, for you folks that still use film, and a darkroom.

Q46. is a tricky one Confused . a,b are the same MDCT scanners (spiral and helical meaning the same thing). d,e are not scanners. All CT scanners if used properly can produce low dose. I would think since the EBT is a beam rather than mechanical rotation, may be the right answer.

Any other thoughts from my fellow CT Tech's Question
