Abstract
A simplified method of absolute quantitation of activity in any region of the body is presented utilizing a series of views acquired with a scintillation camera linked to a computer. An accuracy of ±6% may be achieved. No additional programming needs to be added to the standard nuclear medicine computer software and a knowledge of the attenuation coefficients involved and the shape or position of the organs examined is not presupposed or estimated. Attenuation correction is performed using a transmission image as one of the sequence of camera views. The phantom measurements used to evaluate the technique are decsribed and some clinical results presented.
