Abstract
A processor is provided, and the processor specifies a high-attenuation substance region in a projection image acquired by imaging a subject including a high-attenuation substance using a CT apparatus, and derives a corrected projection image by performing correction on the high-attenuation substance region in the projection image to suppress a difference in image quality between the high-attenuation substance region and other regions outside the high-attenuation substance region.
Claims10
An image processing apparatus comprising:
- a processor,
- wherein the processor is configured to:
- specify a high-attenuation substance region in a projection image acquired by imaging a subject including a high-attenuation substance using a CT apparatus;
- and
- derive a corrected projection image by performing correction on the high-attenuation substance region in the projection image to suppress a difference in image quality between the high-attenuation substance region and other regions outside the high-attenuation substance region.
An image processing method comprising:
- causing a computer to:
- specify a high-attenuation substance region in a projection image acquired by imaging a subject including a high-attenuation substance using a CT apparatus;
- and
- derive a corrected projection image by performing correction on the high-attenuation substance region in the projection image to suppress a difference in image quality between the high-attenuation substance region and other regions outside the high-attenuation substance region.
A non-transitory computer-readable storage medium that stores an image processing program for causing a computer to execute:
- a procedure of specifying a high-attenuation substance region in a projection image acquired by imaging a subject including a high-attenuation substance using a CT apparatus;
- and
- a procedure of deriving a corrected projection image by performing correction on the high-attenuation substance region in the projection image to suppress a difference in image quality between the high-attenuation substance region and other regions outside the high-attenuation substance region.
