Abstract: 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.

Abstract: A radiographic apparatus or system for imaging a dynamic state or process of an object such as a human body includes an indication unit for performing dynamic state guiding indication using a perceivable pattern corresponding to a dynamic state or motion to be engaged in by the patient, and an image acquisition unit for acquiring a plurality of radiographs of the human body. The resulting radiographs can be reviewed for diagnosis, and can be stored, either locally or at a remote location.

Abstract: An X-ray beam transmitted through an object is transmitted through a grid, which has been moved to the X-ray irradiation position, and reaches a panel sensor after scattered X-rays are removed by the grid. Image processing is done on the basis of a reduced image input from the panel sensor. As the reduced image, an image reduced to 1/8 the image output from the panel sensor in both the vertical and horizontal directions is used, and the image is binarized by a predetermined threshold value. Noise of the binary image is removed by an opening filter, and lines of the noise-removed image are scanned in the x- and y-directions to form a list of scan start and end points. The average values of these points are calculated to determine an irradiated region. By extracting an image of the irradiated region from the panel sensor, fluoroscopic image observation and still image photographing are efficiently done using a panel sensor with a large photographing frame.

Abstract: 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.
