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 2):
The dynamic analysis apparatus according to  claim 1 , wherein the extraction section extracts the pulmonary blood flow signal by subtracting a signal waveform of a ventilation component generated by using machine learning from a temporal change waveform showing a temporal change of the pixel signal value in the chest dynamic image after conversion by the conversion section.
