摘要： It is an object of the invention to provide an X-ray diagnosis apparatus having an X-ray plane detector capable of removing the influence of a scattered X-ray by using a grid and also preventing a Moire image. An X-ray image transmitted through a target object is sensed by a plane detector in units of pixels which are two-dimensionally arranged at a predetermined pitch. A scattered X-ray incident on the plane detector is removed by a scattered ray removing grid having plate-like X-ray shielding members and arranged on an X-ray incident side of the plane detector. The X-ray shielding members are arranged such that an X-ray shielding pattern on the X-ray incident surface of the plane detector has a pitch corresponding to an integer fraction of the arrangement pitch of the pixels. When a steady positional relationship is kept between the pitch of the X-ray detection elements and the period of the fringe pattern of the X-ray which is shielded by the grid, a Moire image can be prevented.

摘要： A diagnostic X-ray apparatus includes an X-ray tube, an image intensifier for converting an X-ray image of an object under examination to an optical image, a solid state image sensor device for detecting the optical images produced by the image intensifier and converting the optical means into a series of video signals, a CCD driver generating field shift pulses for driving the solid state image sensor device at a predetermined rate, pulse width determining means for determining a pulse width of the X-ray pulses, and X-ray control means for controlling an emission period and timing of the X-ray pulse emitted from the X-ray tube. In the case that the solid state image sensor device performs interlaced scanning in a field storage mode, commencing with the second frame when the field shift pulse is generated by the CCD driver, the X-ray pulse continues to be emitted from the X-ray tube for a half of the pulse width determined by the pulse width determining means in the first frame. In case that the solid state image sensor device performs interlaced scanning in a frame storage mode, X-ray pulses having a pulse width determined by the pulse width determining means are emitted in the same field of each frame.

摘要： Pixel data in a region of a flat panel detector is obtained and displayed. For example, pixel data in a region irradiated with X-ray is obtained and displayed. The region to be irradiated with-the X-ray is estimated according to a degree of opening of an X-ray beam limiting device and a distance between the X-ray beam limiting device and the flat panel detector. Further, it can be determined from pixel data value of the flat panel detector also. A region of a patient can be also determined from the pixel data. Thus, an image corresponding to the entire flat panel detector, an image corresponding to an X-ray irradiation region and an image corresponding to a patient region can be displayed. A resolution for obtaining the pixel data is changed corresponding to the size of a region in the flat panel detector whose pixel data should be obtained and a processing resolution of an image processing means at post step. Particularly in an X-ray diagnostic apparatus of bi-plane structure, an observation region can be traced flexibly.

摘要： A TFT array structure formed on a glass substrate employs an aluminum alloy for the wiring patterns of signal lines and scanning lines. Besides, on the glass substrate, a terminal structure is formed near the terminating end of each of the wiring patterns. The terminal structure includes a terminal pattern which is formed of the same MoW layer as that of capacitor lines of the TFT array structure. Thus, the TFT array structure holds a repair facility equal to that of the prior art while realizing the enhancement of an operating speed and the reduction of image noise owing to the lowered resistances of the scanning lines and signal lines.

摘要： A magnetic immunoassay system with a mechanism for compensating the direct current residual magnetic field in the vicinity of the specimen measurement position, in a direction perpendicular to the magnetic marker direction of magnetization for the measurement target. This invention reduces the effects of the magnetic field emitted from the unbound magnetic marker due to the residual magnetic field in the specimen solution and detects with high sensitivity the signal of the bound target magnetic marker. The magnetic field at the measurement position is regulated so as to intersect the direction of magnetization of the magnetic marker for the measurement target, in order to make the magnetization direction of the magnetic marker that is unbound due to residual magnetism or remanence in the sample solution, intersect the magnetization direction of the magnetic marker for the measurement target. The signal of the bound target magnetic marker can be therefore measured with high sensitivity since it is isolated from the unbound magnetic marker signal.
