Abstract:
A dynamic analysis apparatus may include a setting section which sets a target region in a lung region of a chest dynamic image; a conversion section which calculates a representative value of a pixel signal value in the target region, and converts the pixel signal value; an extraction section which extracts a pulmonary blood flow signal from the image; and a calculation section which calculates a change in the pulmonary blood flow signal, and calculates a feature amount regarding pulmonary blood flow. The setting section may determine a size of the target region based on a size of a body part other than a lung blood vessel, a movement amount of a body part other than the lung blood vessel or subject information of the chest dynamic image, the subject information regarding a subject of the radiation imaging, and the setting section may set the target region.

Claim (Index 1):
A dynamic analysis apparatus, comprising:\n a setting section which sets a target region in a lung region of a chest dynamic image which is obtained by radiation imaging; a conversion section which calculates a representative value of a pixel signal value in the target region set by the setting section, and converts the pixel signal value in the target region on the basis of the calculated representative value; an extraction section which extracts a pulmonary blood flow signal from the chest dynamic image after conversion by the conversion section; and a calculation section which calculates a change amount of the pulmonary blood flow signal extracted by the extraction section, and calculates a feature amount regarding pulmonary blood flow on the basis of the calculated change amount of the pulmonary blood flow signal wherein the extraction section extracts the pulmonary blood flow signal by a method using machine learning.
