FLOW QUANTIFICATION APPARATUS AND FLOW QUANTIFICATION METHOD

摘要

PPROBLEM TO BE SOLVED: To provide a flow quantification apparatus and a flow quantification method which take a small amount of operation and can evaluate a highly accurate flow value which reflects the actual behavior of a flow (a tissue blood current) more accurately. PSOLUTION: A flow quantification apparatus is equipped with a means for seeking a plurality of tracer doses in a unit voxel corresponding to each of a plurality of known flows by applying the representative parameter of an imaging area tissue of a subject to a model to indicate the condition that the blood current of the subject diffuses into a tissue, a means which approximates the relationship between the plurality of known flows and the two or more tracer doses by a nonlinear formula, and a means which memorizes a corresponding relation based on the nonlinear formula as a memory table or a conversion equation.
