Determination of Organ Area: Application to Thyroid

A method has been developed for the quantification of a projected organ area using a standard gamma camera with pinhole collimation and computer processing of two vertically displaced images. Formulae have been derived expressing the uniquely determined quadratic relationship between object area and...

Description
Summary:A method has been developed for the quantification of a projected organ area using a standard gamma camera with pinhole collimation and computer processing of two vertically displaced images. Formulae have been derived expressing the uniquely determined quadratic relationship between object area and aperture distance with respect to projective image areas. This technique is extremely simple and its successful application to thyroid imaging is described.
