Title:
IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND PROGRAM
Document Type and Number:
Japanese Patent JP2019068952
Kind Code:
A
Abstract:
To provide a technology to improve the quality of an image generated by using a radiation ray of a plurality of types of energy.SOLUTION: An image processing device includes a filter part for subjecting each of a first signal component and a second signal component obtained by irradiating a subject with a radiation ray of a plurality of types of energy to recursive filtering, and a generation part for generating a dynamic image based on the first signal component and the second signal component subjected to recursive filtering. A filter coefficient of the recursive filtering for the first signal component and a filter coefficient of the recurve filtering for the second signal component are different from each other.SELECTED DRAWING: Figure 7
