A radio therapy system includes a first x-ray source. The first x-ray source is configured to produce first x-ray photons in a first energy range suitable for imaging and project the first x-ray photons onto an area designated for imaging. The system includes a second x-ray source configured to produce second x-ray photons in a second energy range higher energy than the first energy range, produce third x-ray photons in a third energy range higher energy than the first energy range, project the second x-ray photons onto the area designated for imaging, and project the third x-ray photons onto an area designated for treatment. The system includes an analytical portion configured to collect and combine data to create a composite output including at least one image, the combining based in part on a spectral analysis.

The present invention relates to a lifting apparatus for a pressure paddle, the lifting apparatus for the pressure paddle comprising: a lifting belt rotated by a driving means; a lifting pulley manually rotated by the lifting belt hung thereon; a lifting frame on which the lifting pulley is mounted; and a pressure paddle mounted on the lifting frame.

There is provided a radiographic imaging apparatus capable of facilitating a comparative radiological interpretation of symmetric portions or a temporal comparative radiological interpretation of a same imaging target. The radiographic imaging apparatus includes an image control unit configured to cause a display unit configured to display a plurality of divided screens to display a first radiographic image of a first imaging target on a first divided screen of the plurality of divided screens. The image control unit causes a radiographic image of the first imaging target that is captured at a different time from the first radiographic image or a radiographic image of a second imaging target that is a symmetric imaging target of the first imaging target to be displayed on a second divided screen of the plurality of divided screens as a second radiographic image.

The present disclosure discloses a medical imaging device including a gantry and a first C-arm having an imaging chain. The gantry includes a first supporting arm connecting the first C-arm, a base, a second C-arm connecting the base, and a second supporting arm connecting the second C-arm. The first C-arm may be moveable along the first supporting arm and the second supporting arm may be movable along the second C-arm.

A radiographic image capturing system includes the following. A capturing stand includes a holder to hold radiographic image capturing devices. A radiation irradiator irradiates the radiographic image capturing devices loaded in the holder at once. An image processor generates a plurality of images based on image data acquired by the radiographic image capturing devices. The image processor removes a streaky component residing in the generated image to correct the image. Such process includes forming a smoothed image by smoothing with a low-pass filter, and subtracting an interpolation image to extract a streaky image from the smoothing image and adding the streaky image to remove the streaky component. The smoothing includes reflecting smoothing on pixels showing a subject structure using a low-pass filter with a size larger in the horizontal direction compared to pixels other than pixels showing the subject structure.

An imaging system (100) includes an annular bearing (404) with an iso-center (406). The annular bearing includes a stationary side (404.sub.1) and a rotatable side (404.sub.2) with at least one alignment feature (420). The imaging system further includes a rotating gantry (410) mechanically coupled to the rotatable side. The imaging system further includes an imaging component (412, 416, 418). The imaging components includes at least one complementary alignment feature (602, 804) that is complementary to the at least one alignment feature (420, 802, 1200) of the rotatable side. The rotating gantry is between the imaging component and the rotatable side, and the imaging component is aligned with the iso-center through the at least one alignment feature and the at least one complementary alignment feature.

An diagnostic X-ray radiography device and system whereby a subject (M) can be placed on and taken off of an imaging bed safely, easily, and comfortably. In the device and system a placement-accommodating-state memory (21) stores a plurality of placement-accommodating states each consisting of an imaging bed (1) position and orientation and an X-ray tube (4) position that accommodate a given placement state of the subject (M). A placement-accommodating-state control unit (22) is provided that, if a desired placement-accommodating state is specified from among the plurality of placement-accommodating states by means of a control panel (11), makes the position of the imaging bed (1) and the position of the X-ray tube (4) conform to the specified placement-accommodating state. A placement-accommodating state is thus set automatically, so that the subject (M) can be placed and removed from the imaging bed (1) easily without a collimator (4a) attached to the X-ray tube (4) getting in the way.

An apparatus has an upright gantry. A tube arm assembly and a compression arm assembly are rotatably coupled to the gantry. The tube arm assembly independently rotates relative to the compression arm assembly. A controller disposed on the gantry is operably connected to at least one of the tube arm assembly and the compression arm assembly.

Various methods and systems are provided for laser alignment systems, particularly laser alignment systems of medical imaging systems. In one example, a medical imaging system comprises: a gantry; and a laser mount including: a first section fixedly coupled to the gantry; a second section seated within the first section and slideable within the first section; and a third section seated within the second section and rotatable within the second section, the third section adapted to house a laser radiation source.

An extra-oral dental imaging apparatus can obtain a radiographic image of a portion of a head of a patient. Exemplary dental apparatus and/or method embodiments can position a subject for dental radiographic imaging by providing a bitable dental arch mounting apparatus to offset the antero-posterior plane of the dental imaging apparatus and the plane of symmetry of the dental arch mounting apparatus. In one embodiment, the offset can be provided by a tilted dental arch mounting apparatus (e.g., relative to the horizontal).
