RE: CT Dose calculation

["Frye, Douglas" <DFrye@clarian.com>]

Dear M. Bala,

	I refer you to an excellent article by Felmlee, et, al in AJR
154:185-190. 1990.  This requires determination of the CTDI or MSAD with a
pencil ionization chamber in a suitable phantom.  There are also excellent
reviews in the 1995 AAPM summer school proceedings.  Consultation with a
qualified diagnostic medical physicist may also prove beneficial.
