What is this page all about? It's for radiologists to use for CT scanning ( "cat scans" or "computed tomography"). It's like a recipe for prescribing medicine according to the patient's body weight.

It might seem a little strange that this website has a variety of health/medical topics, including body mass index, body surface area, ideal weight, breast cancer, and CT scanning protocols (here), but there is a slight common thread... that big people and small people aren't the same, but you can treat eveyone equally by making logical adjustments.
