Compartmental analsys system, compartmental analysis method, compartment analyzer, program, and recording medium

摘要

One object of the present invention is to perform compartmental analysis of the dynamics of a tracer in the brain, and the present invention provides a compartmental analysis system including a measurement apparatus that measures the strength of an electromagnetic wave from a tracer and a compartmental analyzer that performs compartmental analysis of the dynamics of the tracer in the brain on the basis of the strength of the electromagnetic wave, wherein the compartmental analyzer includes a rate constant calculation unit that calculates a rate constant when the tracer moves between compartments on the basis of the strength of an electromagnetic wave in a first compartment corresponding to the cerebral blood vessel in the brain or an input function in the first compartment, the strength of an electromagnetic wave in a second compartment corresponding to the brain tissue in the brain, and the strength of an electromagnetic wave in a third compartment corresponding to the cerebral sulcus or cerebral ventricle in the brain.

主权项

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.
