A computer method has been developed to compensate for patient motion which is a serious problem in real scintigraphic studies. The developed computer method compensates for translational and rotational differences between images acquired while the patient was not moving and images acquired after the occurrence of motion.

Methods for the estimation of particle concentration profiles from numerical data are presented. The estimation techniques described, which involve the use of Fourier transforms, make more efficient use of data than do simple histogram techniques. Additionally, Fourier methods of analysis have been used to test theoretical models of experimental data.
