摘要： PROBLEM TO BE SOLVED: To easily widen an adaptable focus-image reception face distance range by scattered X-ray removing grids disposed in one device.
SOLUTION: Among two scattered X-ray removing grids 12A, 12B differing in the adaptable focus-image reception face distance range, the scattered X-ray removing grid corresponding to the present set value of a focus-image reception face distance SID is selected and can be set at the arrangement position 2a in front of a two-dimensional X-ray detector 2, and the scattered X-ray removing grid not corresponding to the present set value of the focus-image reception face distance SID is retreated to the evacuation position 2b on the side of the two-dimensional X-ray detector 2. Accordingly, the adaptable focus-image reception face distance range grows into a wide range that is the sum of all of respective focus-image reception face distance ranges of two scattered X-ray removing grids 12A, 12B by the scattered X-ray removing grids in one device, and only the constitution which can be easily achieved to enable the reciprocative movement of the scattered X-ray removing grids 12A, 12B between the arrangement position in front of the two-dimensional X-ray detector 2 and the evacuation position on its side is required.

摘要： PROBLEM TO BE SOLVED: To provide an image evaluation method which can quantitatively show the visibility of low contrast and a fine line object for clinical practice, and X-ray fluoroscopic equipment using it.SOLUTION: In an image evaluation method and X-ray fluoroscopic equipment 1 using it, an image which suppresses noise components can be created by averaging the X-ray fluoroscopic image of two or more frames. Therefore, because the edge part is not buried in the noise component even when the difference of pixel values between the edge part of a metal plate 11 and an object M under test is small and low contrast, an appropriate peak value can be obtained from an edge weighted image. Also, the peak value of the edge part is obtained from the edge-weighted image. Because the peak value indicates such a large value that the edge part in an average image is not blurry and is sharp, it permits the correlation of an index value which is calculated by dividing the peak value with standard deviation can correlate with the visibility of a low contrast and fine line object.
摘要翻译：要解决的问题：提供可以定量显示用于临床实践的低对比度和细线对象的可视性的图像评估方法，以及使用它的X射线荧光检查设备。解决方案：在使用它的图像评估方法和X射线透视设备1中，可以通过对两个或更多个帧的X射线透视图像进行平均来创建抑制噪声分量的图像。因此，即使当金属板11的边缘部分和被测试物体M之间的像素值的差小且对比度低时，边缘部分也不会被埋在噪声分量中，所以可以从边缘加权图像。此外，从边缘加权图像获得边缘部分的峰值。由于峰值表示平均图像中的边缘部分不模糊且锐利的值很大，所以允许通过将峰值除以标准偏差计算的指标值与相关的可见度相关联低对比度和细线对象。版权所有（C）2013，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide X-ray equipment which can prevent a region of interest from deviating from a central part of an image monitor, even if each part is driven only by providing instructions on test classification, by prestoring an appropriate isocenter for each test classification.
SOLUTION: When a photographer provides the instructions on the inspection classification in an instructive part 42, a main control part 35 operates a supporting arm 13, an X-ray imaging system control part 41, and a top panel control part 29 in such a manner that a position on the basis of "a height" from a top panel 3, according to the inspection classification prestored in a storage part 43, "a minor-axis-direction position" in the horizontal surface of the top panel 3, and "a major-axis-direction position" serves as the isocenter IC. Thus, even if the photographer appropriately moves the supporting arm 13, the region ROI of interest according to the inspection classification is displayed on the central part of the image monitor 39. Consequently, the region of interest can be prevented from deviating from the central part of the image monitor 39, even if each part is driven only by providing instructions on the inspection classification.

摘要： PROBLEM TO BE SOLVED: To provide a pressure tube unit which realizes a mechanism to store a pressure tube in a penetrative photographing table, or the like, with a compact and simple structure and realizes the excellent rigidity at the same time, and a radiation penetrative photographing apparatus equipped with the same.
SOLUTION: In the pressure tube unit of the X-ray penetrative photographing apparatus of this invention, a supporting arm portion is constituted to be elastic as a sliding structure of a cone arm (a supporting arm) 27 whose pointed head is fixed to the pressure tube 28 and an L-shaped arm 26. The cone arm 27 is axially connected to a carriage 23 by a stay 29 with a pin 29b and the L-shaped arm 26 is also axially connected to the carriage 23 by the other pin 26a. Since the cone arm 27 is slid by the rotation of the carriage 23 at the time of a withdrawal action (a rise of the carriage 23) of the pressure tube and is compressed short in the L-shaped arm, the pressure tube unit can be compactly stored with the simple structure and is superior to the one which is axially connected by a pinion or the like, in the rigidity of the connection section.

摘要： PROBLEM TO BE SOLVED: To provide an X-ray imaging apparatus properly exposing an image.SOLUTION: In the X-ray imaging apparatus 1, first and second region extraction parts 29, 30 extract two regions A, B located in the center of an acquired image and have different sizes. First and second average pixel value calculation parts 31, 32 calculate average pixel values of the extracted regions A, B. An X-ray condition setting part 37 sets an X-ray condition for irradiation by use of an X-ray tube 5 based on the average pixel value of one of the plurality of extracted regions. A comparison selection part 33 compares the average pixel values calculated in the regions A, B and selects the minimum average pixel value. By selecting the minimum pixel value, the X-ray condition is set such that the X-ray condition becomes higher. However, by selecting the minimum average pixel value, the regions A, B can be correctly selected, so that the image where a desired portion is properly exposed can be acquired.

摘要： PROBLEM TO BE SOLVED: To provide a fluoroscopic apparatus which solves an issue that a method assembling a cantilever type cassette holder to an image system mobile part of a fluoroscopic apparatus and placing the cassette containing an X-ray film on a front face part of a top plate is used for a subject not to take an unnatural posture when imaging a breast part using the fluoroscopic apparatus, but a cassette holder configured in such a manner is supported by only one side end part causing concern that the cassette holder is bent to the top plate side and broken when the subject unpreparedly leans against the cassette holder.
SOLUTION: An arm member 4 is assembled by a latch mechanism to a surface to a top plate side around the end part opposite to a part wherein two longitudinal line parts of an H-shape frame 1 of a cassette holder 17 are assembled to an image system mobile part 8, and the arm member 4 is horizontaly fixed to the top plate as showed in figures during imaging. Thus concern of breakage of the cassette holder 17 is eliminated because the arm member 4 is in contact with the top plate and a further bend is prevented by a slight bend of the frame 1 even if a subject unpreparedly leans against the cassette holer 17.

摘要： PROBLEM TO BE SOLVED: To provide a fluoroscopic radiographic device requiring no additional Bucky's radiographic device by preventing the moving range of a second X-ray tube device suspended from a ceiling or the like from being limited.
SOLUTION: A general fluoroscopic radiographing is carried out by use of a first X-ray tube device 3 and an FPD 15 set on the upper part of a top plate 12. When a teleradiographing is carried out, the FPD 15 is rotated 360° around a rotating shaft 14 to turn an input surface 15a upward, and the top plate 12 is longitudinally moved. A lifting part 13 having the FPD 15 mounted thereon is lowered along a support part 4a to lower the FPD 15 to the reverse side of the top plate 12. The FPD 15 is moved along a guide channel 8 in parallel to the top plate 12 and set under the position to be imaged of a subject, and the second X-ray tube device suspended from the ceiling is set from above to take the image.
