摘要： X-ray examination of objects, which may be very large objects such as aircraft, boat hulls or lengthy pipelines, is accomplished with an x-ray source (22) having a moving x-ray origin point (29) that is scanned in a raster pattern (33). At least one x-ray detector (23) having a very small x-ray sensitive area (38) is disposed behind or within the object (41) and provides an output signal indicative of internal characteristics of an adjacent region of the object (41). The source (22) and detector (23) undergo relative travel at least in a lateral direction during the examination to provide a sequence of different x-ray views that may include views of successive regions of the object (41), views from different angles and stereo views. X-ray images are produced at one or more monitor screens (43) by sweeping a point of light in a raster pattern corresponding to that (33) of the x-ray source (22) while modulating the intensity of the point of light in accordance with the output signal of the detector (23). An array (39) of spaced apart detectors (23) may be used to simplify examination of large objects or to speed examination of small objects.

摘要： X-ray images are produced on a monitor display screen (32) by situating the subject between a detector (13) having a minute x-ray sensitive area and an x-ray source (12) having an extensive anode plate (18) on which an x-ray origin point is swept in a raster pattern similar to the raster of the display monitor. Operating parameters of the x-ray source are controlled by digital data processing circuits (43) which enable magnification of operator selected areas of the image by reducing the size of x-ray source raster pattern and repositioning of the raster pattern on the anode plate in response to operator actuation of one or more computer input devices.
In the preferred form, the system also enables image enhancements and control of image characteristics such as contrast and brightness in response to actuations of the input devices or in response to programming. X-ray exposure and image acquisition time may be reduced by operator selection of only specific areas of particular interest for high resolution scanning. In the preferred form, the apparatus can detect a particular gray level in the image data and relocate the scan to image the region where the gray level is found. This enables fixed imaging of a moving object.

摘要： Visual display of dental or other radiographic images is realized with an X-ray tube (13) in which an electron beam (23) is scanned through an X-Y- raster in synchronism with X-Y-sweep signals of a cathode ray display tube (17).
The intensity signal for the display is derived from an X-ray detector (44) receiving X-rays passing through an object (12) to be imaged.
The detector (44) is. arranged in a probe (14a) supported relative to the X-ray tube (13.) at any location and a plurality of such probes (14a) of different configuration is provided to change focal length, to accomodate to different detector placements, to enhance patient comfort and to enable production of.both periapical, and wider angle pantomographic dental images. High image definition with reduced radiation dosage may be provided for. Mounting means enable changes of collimator (29a) in conjunction with changes of the probe to change focal length.
A control circuit (16) modifies the X-Y-sweep signals and modulates electron beam to correct for image distortions.
