A composition information obtaining unit calculates a mammary gland/fat ratio and a first information obtaining unit obtains imaged contrast information representing a contrast of the radiation image. A second information obtaining unit sets target application condition of X-ray, and obtains target contrast information representing an intended contrast for the radiation image based on the intended application condition. A contrast correction amount determination unit determines a contrast correction amount based on the imaged contrast information and the target contrast information. An image processing unit performs image processing, including gradation processing based on the determined contrast correction amount, on the radiation image, and obtains a processed radiation image.

Disclosed are a mammography system and a mammography imaging method that can prevent a subject from being exposed to radiation more than necessary by setting an optimum imaging condition according to a thickness of a subject's breast, and can obtain a high-quality medical image by setting an optimum FOV and correcting projection data according to the thickness of the breast. The mammography system includes: a mammography imaging device including a detector and an X-ray tube, and obtaining X-ray image data of a subject's breast from multiple angles; a thickness obtaining unit obtaining information on a thickness of the breast; and a rotation angle calculator calculating a rotation angle range of the X-ray tube, based on the information of the thickness of the breast, wherein the mammography imaging device obtains the X-ray image data from multiple angles by performing radiography while rotating the X-ray tube within the rotation angle range.

During the generation of a panoramic x-ray recording, the use of semi-transparent x-ray screens allows the patient's x-ray exposure to be reduced when partial x-ray images are created, in spite of relatively large overlapping areas between the partial x-ray images.

A radiographing system includes a mobile terminal configured to store an examination time of a subject that is based on examination-related information about the subject, a radiographing apparatus configured to take a radiation image of the subject based on the examination-related information and to store an imaging time of the radiation image, and an association unit configured to associate the radiation image with the examination-related information based on the imaging time and the examination time.

In scan data retrieval, a mesh is fit (32) to surface data of a current patient, such as data from an optical or depth sensor (18). Meshes are also fit (48) to medical scan data, such as fitting (48) to skin surface segments of computed tomography data. The meshes or parameters derived from the meshes may be more efficiently compared (34) to identify (36) a previous patient with similar body shape and/or size. The scan configuration (38) for that patient, or that patient as altered to account for differences from the current patient, is used. In some embodiments, the parameter vector used for searching (34) includes principle component analysis coefficients. In further embodiments, the principle component analysis coefficients may be projected to a more discriminative space using metric learning.

Disclosed herein are an X-ray imaging apparatus for optimizing radiography conditions upon radiography, and a control method thereof. The X-ray imaging apparatus includes: an input device configured to receive information about a patient; and a controller configured to conduct a search for a previously obtained X-ray image related to the information about the patient and a previously set radiography condition related to the information about the patient, and to set a radiography condition for a main-shot based on a result of the search.

The present invention relates to a device (1) for determining image quality of a radiogram image, the device comprising: an acquiring module (10), which is configured to acquire the radiogram image; a segmentation module (20), which is configured to segment a thoracic bone structure on the acquired radiogram image into segmented thoracic bone structure contours and a tissue structure on the acquired radiogram image into segmented tissue structure contours; and a quality-determination module (30), which is configured to determine a image quality coefficient for the acquired radiogram image based on a comparison of a first position of the segmented thoracic bone structure contours with a second position of the segmented tissue structure contours.

Provided is a radiographic apparatus configured to obtain an animated image of a fluoroscopic image, and thereafter complete fluoroscopy temporarily for taking a static image or the animated image for diagnosis, the radiographic apparatus allowing taking an image of a subject with suitable brightness. The apparatus determines a control condition (radiography condition) of an X-ray tube for taking the static image in accordance with the control condition of the X-ray tube upon obtaining the fluoroscopic image. With the disclosure, brightness of the subject contained in the fluoroscopic image is also regarded upon determination of the radiography condition. This achieves obtaining the suitable radiography condition even when obtaining the animated image stops before radiation has appropriate intensity during obtaining a live image. Accordingly, the apparatus in the disclosure allows obtaining a clear image with appropriate exposure.

A method for exposure control setup for a volume radiographic imaging apparatus obtains a reconstructed image volume of a subject acquired from the imaging apparatus using a set of x-ray technique settings. An image slice from the reconstructed image volume displays in at least a first rendering having a first corresponding noise factor and a second rendering having a second corresponding noise factor, different from the first noise factor. An operator instruction selects one of the at least first and second renderings and stores the corresponding noise factor for the set of x-ray technique settings. An automatic exposure control of the imaging apparatus is configured according to the stored noise factor.

Described is an in-scan phantom for use during an imaging procedure. The phantom can include at least one measuring insert and/or at least one measured insert. The measuring insert may have radiation detecting capabilities while the measured insert may include a radioactive material. Also described is an imaging modality system that includes an imaging modality and an in-scan phantom as well as methods of using the in-scan phantom for imaging a patient or performing a scout scan.
