摘要： PURPOSE:To obtain a tomographic picture of high picture quality having a little picture distortion or blurring by sending a detecting signal from a position information detector composed of a zebra scale and a photosensor to a controller and controlling the exposure of a radiant ray from a radiant ray source and the taking-in of projecting data to a recorder according position information. CONSTITUTION:The position information of relative movement for a radiant ray source 1 and a radiation detector 2 are detected by a position information detector 18 and the exposure of the radiant ray from the radiant ray source 1 and the taking-in of the projecting data to a recorder 6 is controlled. Then, the position information of the radiant ray source 1 is recorded to the recorder 6 in correspondence to the projecting data in respective projecting positions. Accordingly, concerning the respective projecting data, which projecting position of the radiant ray source 1 is photographed can be correctly made correspondent. Thus, in the correction of the picture distortion, a distortion vector in each projecting position can be exactly obtained and the correction of the picture distortion can be executed with high accuracy by using this distortion vector. In the shift addition of the respective projecting data, shift quantity can be exactly obtained at every projecting position and the shift addition can be executed with the high accuracy by using this shift quantity.

摘要： PURPOSE:To clearly display a contour, etc., of internal organs, etc., so that a diagnosis can be executed easily by changing a gradation so that a density difference of a dark part and a bright part becomes large within a range of a local part by a gradation changing means, when the local part is specified by an area designating means. CONSTITUTION:A testee 2 on a table 1 is irradiated with X rays from an X-ray tube 3, the X rays which transmit through the testee 2 are detected by a detector 4, and an optical image is outputted as electric information from a TV camera 6. Based on this electric information, a histogram being an appearance frequency distribution of an image data digital value is formed by a histogram forming circuit 9, and conversion data for executing a gradation processing is formed by a look-up table 10. Also, in this case, in the case a console 13 is operated and an interest area is specified, picture element information by an address corresponding to the interest area is read out, and change data for changing a gradation so that a density difference of a dark and a bright part becomes large is formed by a look-up table 15 and outputted to a monitor 12.

摘要： PURPOSE:To rapidly switch from fluoroscopy to photographing by heating a photographing cathode prior to switching of the cathode bias potential at the time of switching from fluoroscopy to photographing. CONSTITUTION:This DR device conducts photographing of a digestive organ of an examined body 2 by use of a TV camera 1. The X-rays from an X-ray tube 4 lead to an X-ray collimator 8, penetrate the examined body 2, and is converted into an optical image by an X-ray image intensifier (I.I) 3, and this image is formed on the TV camera 1 by an optical system 9. The video signal from the TV camera 1 is made into digital form by an A/D exchanger 5, stored in an arithmetic memory part 6, further processed, and indicated as an image on a display part 7 consisting of a CRT monitor. A system controller 13 controls a high voltage generator 10, a starter 11, and the arithmetic memory part 6 by the instruction of an operator from an operating board 12.
