摘要： [Aim] To generate a high quality image in which a periodic pattern, such as a folding distortion component, which is caused by a spatial frequency component of a grid image, is suppressed while a subject component is maintained in an image signal generation method and apparatus that generates an image signal by reading a storable phosphor sheet on which a radiographic image including the grid image is recorded.
[Solution Means] A first processed signal (Sh) 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 (Sc) of an image included in the extracted first processed signal is extracted from the first processed signal. A second processed signal (Sp) is extracted by subtracting the first processed signal (Sh) from the image signal (Sd) and also by adding the extracted subject component (Sc) to the image signal (Sd).

摘要： 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.

摘要： [Problems to be Solved]
When an area in which it is difficult to detect a periodic pattern is further included in a radiation field area, allowing a periodic pattern to be detected accurately.
[Means for Solving the Problems]
The image obtaining unit (31) obtains a radiation image (P0) from the radiation detector (2), the radiation field area detection unit (32) detects a radiation field area (P1) from the radiation image (P0). The analysis area setting unit (33) detects a direct radiation area, a superabsorbent body area, and a high noise area as the areas where a periodic pattern is unlikely to present and sets an analysis area (P2) by excluding these areas. The frequency analysis unit (34) performs a frequency analysis only on the analysis area (P2) and detects a frequency component of the periodic pattern arising from a grid. The filtering processing unit (35) removes the frequency component of the periodic pattern arising from the grid from the radiation image (P0).

摘要： [Aim] To identify the inclination of a periodic pattern included in an image based on frequency components corresponding to the periodic pattern, and the frequency components having been detected with respect to plural directions.
[Solution Means] A subject component removed signal (Sh) is obtained from an image signal (Sd) representing an image by performing, with respect to a first direction and/or a second direction that is different from the first direction, one-dimensional filtering processing using a subject component removal filter (HPF) that removes a low frequency component including a subject component of the image to roughly remove the subject component. Further, frequency components corresponding to the periodic pattern in the subject component removed signal (Sh) are detected with respect to both of the first direction and the second direction.
