Document Type and Number:
Japanese Patent JP2020014562
Kind Code:
A
Abstract:
To provide a dynamic image analysis apparatus, a dynamic image analysis method, and a program capable of acquiring a blood flow analysis image by relatively simple procedures of analysis of a dynamic image with only a small burden on a subject.SOLUTION: A dynamic image analysis apparatus includes: an image acquisition unit 51 for acquiring an X-ray dynamic image composed of a plurality of continuous frame images; a logarithmic transformation processing unit 53 for subjecting a pixel value of the X-ray dynamic image to logarithmic transformation, and generating a logarithmic transformation image; an analysis object setting unit 52 for setting one frame image as a reference frame image on the basis of a heartbeat phase for at least one of the X-ray dynamic image and the logarithmic transformation image; and a blood flow analysis unit 54 for taking a difference or a ratio between the X-ray dynamic image as the reference frame image and the X-ray dynamic image as a comparison frame image which is another frame image, or taking a difference or a ratio between the logarithmic transformation image as the reference frame image and the logarithmic transformation image as the comparison frame image, and generating a blood flow analysis image on this basis.SELECTED DRAWING: Figure 1
