Abstract:
1. A compartmental analysis system that performs compartmental analysis of dynamics of a tracer in a brain, comprising: a measurement apparatus comprising at least one processor that measures a strength of an electromagnetic wave from the tracer in the brain; and a compartmental analyzer comprising at least one processor that performs compartmental analysis of dynamics of the tracer in the brain on the basis of the strength of the electromagnetic wave from the tracer in the brain measured by the measurement apparatus, wherein the compartmental analyzer includes a rate constant calculation unit comprising at least one processor that calculates at least one rate constant when the tracer moves between compartments of a brain on the basis of a strength of an electromagnetic wave in a first compartment corresponding to a cerebral blood vessel in the brain measured by the measurement apparatus or an input function in the first compartment, a strength of an electromagnetic wave in a second compartment corresponding to brain tissue in the brain measured by the measurement apparatus, and a strength of an electromagnetic wave in a third compartment corresponding to a cerebral sulcus or a cerebral ventricle in the brain measured by the measurement apparatus.
