Dynamic analysis device, dynamic analysis system, dynamic analysis method and non-transitory computer readable storage medium

A dynamic analysis method comprising:

• performing filtering on a dynamic image in a feature quantity space formed of two or more axes with feature quantities of the respective axes, the dynamic image being obtained by dynamic imaging performed by emitting radiation to an examination target site;
• and
• calculating a feature quantity relating to a dynamic state of the examination target site based on the filtered dynamic image.

A non-transitory computer readable storage medium storing a program for a computer to perform:

• performing filtering on a dynamic image in a feature quantity space formed of two or more axes with feature quantities of the respective axes, the dynamic image being obtained by dynamic imaging performed by emitting radiation to an examination target site;
• and
• calculating a feature quantity relating to a dynamic state of the examination target site based on the filtered dynamic image.
