    Please have a look at 1:16 [min:sec]. When there is material with an attenuation coefficient larger than 1, then the attenuation would be more than 100%. The transmission is actually exp(-µd). With µ=0.181/cm the attenuation would be ~16.5%.

    U should go step by step with bone and lung... especially when writing out number line

    Great video. Who assigns the the WW and L? Is it the same for all vendors/machines?

    Good luck with your registry! In my opinion this is one of the trickiest concepts to grasp. It's something you will get a good grasp on as you work more with both CT and general xray.
