It is detected whether a grid stripe is present in a radiographic image. In a case in which the grid stripe is detected, a process of removing the grid stripe from the radiographic image is performed and the radiographic image is displayed. In a case in which the grid stripe is not detected, a process of removing a scattered component from the radiographic image is performed and a radiographic image subjected to the scattered radiation removal process and a radiographic image before the process are displayed.

Radiographic image processing device, method, and program

A radiographic image captured by irradiating a subject with radiation is acquired. A scattered radiation removal unit removes a scattered component from the radiographic image using at least imaging conditions. A correction information acquisition unit acquires correction information for correcting the degree of removal of the scattered component and changes the imaging conditions on the basis of the correction information. The scattered radiation removal unit performs a process of removing the scattered component from the radiographic image on the basis of the changed imaging conditions.

A radiographic imaging system includes an imaging apparatus which takes a radiographic image of a subject and outputs image data of the radiographic image; an image processing apparatus which performs image processing of at least one of an exposure field recognition process and a trimming process on the image data of the radiographic image; an image processing information storage apparatus which stores the imaging conditions of the radiographic image and image processing information which indicates the image processing and its applicable range in an associated manner; and an image processing information search apparatus which searches for image processing information according to imaging conditions of current imaging, among the image processing information of past imaging stored. The imaging apparatus changes a range of radiation exposure irradiated from a radiation source in accordance with the applicable range of the image processing of the past imaging contained in the image processing information retrieved by the image processing information search apparatus.

Radiographic imaging system

A radiographic tomography apparatus includes a tomosynthetic image capturing section for applying radiation from a radiation source to an examinee at a plurality of different angles, and detecting the radiation transmitted through the examinee with a radiation conversion panel to capture a plurality of tomosynthetic tomography images of the examinee. The radiographic tomography apparatus further includes a still image capturing section for capturing a plurality of still images of the examinee in one image capturing position at different times, and a body motion detector for detecting a body motion of the examinee based on the still images captured by the still image capturing section.

Radiographic tomography apparatus

An image processing apparatus capable of clipping a diagnostic region while retaining the pixel information of the original radiographic image even when the subject is imaged aslant. The image processing apparatus applies trimming processing to a radiographic image acquired by an imaging apparatus for acquiring a radiographic image of a subject and includes an image rotation unit for rotating the radiographic image so that the subject is aligned with a given direction to produce a display image, a diagnostic region designation unit for designating a first diagnostic region clipped with a diagnostic region designation frame represented by a rectangle for the display image, and a trimming processing unit for calculating a second diagnostic region in the radiographic image from a rotation amount of the display image and diagnostic region information representing the first diagnostic region and applying trimming processing to the radiographic image to clip the second diagnostic region.

Image processing apparatus, radiographic image system, and image processing method and program

A tomographic image capturing apparatus includes a radiation source for applying radiation to a subject at a plurality of different angles with respect to the subject, a radiation detector for detecting the radiation which has passed through the subject at each of the different angles and converting the detected radiation into image data, a tomographic image reconstructing unit for processing the image data into a reconstructed tomographic image, and an image capturing sequence setting section for establishing an image capturing sequence of a tomosynthesis image capturing process and a simple image capturing process based on ordering information which represents the tomosynthesis image capturing process for acquiring the reconstructed tomographic image and the simple image capturing process for acquiring a simple captured image.

Tomographic image capturing apparatus and tomographic image capturing method

The image information processing system includes a radiation image generating device for generating a radiation image, an image information processing device having a function of inputting patient information, a function of receiving the radiation image and a function of performing predetermined image processing on the received radiation image, an external memory device for temporarily storing at least one of the radiation image and the processed radiation image in relation to the patient information and an image display device for displaying at least one of the radiation image and the processed radiation image. The image information processing device has a function for making a copy of capture items which include at least the patient information and capture information relevant to the radiation image when there is an indication that the radiation image is a damaged picture.
