Why is there no MAS in radiographic positioning books of mine?
I am learning how to use the x-ray machine to get the certification for it but when I see my radiographic positioning book I see no MAS but I see KVP. I didn't like the cengage learning books that the school provided. The teacher had a book made by Kenneth L. Bontrager that had the Mas on it. So I went and bought it but a newer version of that serious but I didnt see a MAS. I am wondering there has to be a reason why are the books doing this.
