Total Claims: 5
Claim 1
Independent Claim
221 words
A tomography system comprising a source for producing penetrating radiation, such as X-rays or gama-rays, a support arrangement for supporting an object, beam collimating means including a set of slotted masks serving to irradiate an object placed on said support arrangement with one or more diverging beams of radiation, a detector arrangement for converting radiation transmitted through and along the object into electric signals, and an image reconstruction device for processing electric signals, characterized in that the means for deflecting the scanning beam of a video camera which in an optical sense is being rigidly coupled with the output of the detector arrangement, are coupled to a selectively switchable electronic control device by means of which control device the format and/or resolution of the picture as being read out by the video camera can be adjusted to a selected value; a selectively adjustable positioning device being further provided for grouping spatially relative to one another and dependent on the operating mode selected for said electronic control device, the combination of radiation source, slotted masks and detector arrangement with respect to said support arrangement in such a manner that either an overall picture of an object placed on said support arrangement, or a tomographic image of one or more cross-sections of the object portion corresponding to said overall picture can be made.
Claim 2
Dependent Claim
221 words
A tomography system comprising a source for producing penetrating radiation, such as X-rays or gama-rays, a support arrangement for supporting an object, beam collimating means including a set of slotted masks serving to irradiate an object placed on said support arrangement with one or more diverging beams of radiation, a detector arrangement for converting radiation transmitted through and along the object into electric signals, and an image reconstruction device for processing electric signals, characterized in that the means for deflecting the scanning beam of a video camera which in an optical sense is being rigidly coupled with the output of the detector arrangement, are coupled to a selectively switchable electronic control device by means of which control device the format and/or resolution of the picture as being read out by the video camera can be adjusted to a selected value; a selectively adjustable positioning device being further provided for grouping spatially relative to one another and dependent on the operating mode selected for said electronic control device, the combination of radiation source, slotted masks and detector arrangement with respect to said support arrangement in such a manner that either an overall picture of an object placed on said support arrangement, or a tomographic image of one or more cross-sections of the object portion corresponding to said overall picture can be made.
Claim 3
Dependent Claim
39 words
A system according to claim 1, characterized in that said electronic control device comprises an operating mode switching device serving to select the manner in which the picture formed on the input screen of the video camera is scanned.
Claim 4
Dependent Claim
42 words
A system according to claim 2, characterized in that said operating mode switching device is coupled to a command unit serving to adjust said position device for a spatial configuration of the irradiation picture forming means corresponding to the selected operating mode.
Claim 5
Dependent Claim
59 words
A unit comprising a detector device and a video camera connected thereto, the deflection means and the output thereof being coupled to a selectively switchable, electronic control device which, depending upon the selected operating mode, determines the height and width of a scanned image and/or the resolution thereof, which unit forms part of a system according to claim 1.
