Abstract
A method and apparatus are provided for performing non-invasive measurements, and in particular in vivo non-invasive measurements of the total body content of a particular element, or of the content of such elemetn in a particular body area, by use of resonant gamma ray detection. More particularly, gamma rays are generated at the resonant gamma absorption energy level for the element on which measurements are to be made and are passed through the portion of the patient's body for which measurements are to be made. Detected gamma rays passing through the patient's body may be utilized as an indication of the content of such element. The effect of non resonant gamma absorption may be subtracted by also passing gamma rays of non-resonant absorption energy through the same body part and utilizing detected gamma rays at this energy passing through the body to determine the non-resonant absorptions.
