摘要： An X-ray imaging apparatus is provided. The apparatus includes an X-ray sensor unit that detects X-rays, and a control unit that controls driving of an X-ray generator and the X-ray sensor unit. The control unit performs alignment imaging for imaging a still image of a subject. The still image is used as a reference for alignment of at least one of the X-ray generator and the X-ray sensor unit. After the alignment imaging, the control unit performs main imaging for imaging a moving image of the subject. The alignment imaging and the main imaging are performed under the same driving condition of the X-ray sensor unit.

摘要： A compact apparatus can form multi X-ray beams with good controllability. Electron beams (e) emitted from electron emission elements (15) of a multi electron beam generating unit (12) receive the lens effect of a lens electrode (19). The resultant electron beams are accelerated to the final potential level by portions of a transmission-type target portion (13) of an anode electrode (20). The multi X-ray beams (x) generated by the transmission-type target portion (13) pass through an X-ray shielding plate (23) and X-ray extraction portions (24) in a vacuum chamber and are extracted from the X-ray extraction windows (27) of a wall portion (25) into the atmosphere.

摘要： A mammography apparatus includes a detector that detects X-rays transmitted through a breast, and an optically transparent or semitransparent pressing panel for pressing the breast. The apparatus further includes a near infrared ray source that provided between the X-ray source and the pressing panel and arranged in a two-dimensional shape in alignment with the pressing panel, and that is movable between a first position in close contact with the pressing panel and a second position outside an X-ray image capture region. Near infrared image capture is carried out using the near infrared ray source by causing the near infrared ray source to be in the first position, and the near infrared ray source is caused to retract to the second position when carrying out X-ray image capture using the X-ray source.

摘要： In order to reduce the size of a data stream of image data transmitted via a network and to efficiently manage such a data stream, the image data is coded in a highly efficient fashion using a hierarchical coding algorithm, such as a wavelet transformation. When a data stream is being inputted, the data stream is analyzed and input of the data stream is interrupted in accordance with an analysis result. An interrupted stream is generated from the data stream that has already been inputted. The resultant interrupted stream is stored.

摘要： In an apparatus without a helical movement, a reconstruction error considerably increases as a radiation angle increases. In a prior art embodiment, for example, a one-side value of the radiation angle is 9.5 degrees, and it is predicted that the reconstruction error at its periphery considerably increases. In a radiation imaging apparatus including a radiation generating source for radiating radiation to a subject, a rotating unit for rotating the subject exposed to the radiation from the radiation generating source, and a two-dimensional detector for detecting radiation, a distance between the radiation generating source and the two-dimensional detector is approximately set to a value equal to or more than 240 cm.

摘要： N images in a respiratory cycle which are radiographed in year P are input, and binary lung field images are extracted from the respective front chest images. Lung field areas S and lung field heights are then calculated. In forming area and height variation waveforms, regions of the N input images are obtained and plotted. Each image is determined as an image belonging to the inspiration mode or expiration mode. The respective images are sorted and stored. Similar processing is performed for N images in a respiratory cycle which are radiographed in year P+1, and the resultant images are stored. Difference images are obtained from the basic images radiographed in year P+1 and the reference images radiographed in year P for each mode by image analysis, thereby extracting changes over time.
