Abstract:
A first processed signal is extracted by extracting an input spatial frequency component corresponding to a periodic pattern by performing filtering processing on an image signal. A subject component of an image included in the extracted first processed signal is extracted from the first processed signal. A second processed signal is extracted by subtracting the first processed signal from the image signal and also by adding the extracted subject component to the image signal.

Abstract:
It is possible to allow image processing on a radiation image such that the same effect of scattered radiation elimination as when imaging is actually performed using a grid is obtained. When performing processing for eliminating scattered radiation included in radiation transmitted through a subject M on a radiation image imaged by irradiating the subject M with radiation, a characteristic acquisition unit 32 acquires a virtual grid characteristic as a characteristic of a virtual grid assumed to be used to eliminate scattered radiation at the time of imaging of the radiation image. A scattered radiation elimination unit 36 performs scattered radiation elimination processing of the radiation image based on the virtual grid characteristic.

Abstract:
A photoacoustic image evaluation apparatus includes a processor configured to acquire a first photoacoustic image generated at a first point in time and a second photoacoustic image generated at a second point in time before the first point in time, the first and second photoacoustic images being photoacoustic images generated by detecting photoacoustic waves generated inside a subject, who has been subjected to blood vessel regeneration treatment, by emission of light into the subject; acquire a blood vessel regeneration index, which indicates a state of a blood vessel by the regeneration treatment, based on a difference between a blood vessel included in the first photoacoustic image and a blood vessel included in the second photoacoustic image; and display the blood vessel regeneration index on a display.
Abstract:
An image selection unit selects a B2 image signal of which an image blurring amount satisfies a first condition, from a B2 image signal at a first timing T1 or B2 image signals at the second timing T2 to an N-th timing TN. A computed image signal generation unit performs computation based on a B1 image signal at the first timing T1 and a second image signal selected in the image selection unit, thereby generating a computed image signal.
