Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
152 words
An X-ray diagnostic apparatus for urological examinations including an upright column, a frame secured to and vertically movable on the column, a table plate secured as a cantilever to the frame and movable transversely and longitudinally thereon, and an X-ray source secured to the column above the table plate and an image intensifier rigidly secured to the frame below the table plate and aligned with said source and further comprising a cassette carriage movable longitudinally and transversely within the table plate, electric motor means for moving said table plate and carriage respectively, first control means for automatically actuating said motor means to move the carriage between preselected positions, and second control means for partially reversing said carriage movement when the carriage overtravels one of said positions, said first and second control means comprising electric switches and cam means for actuating the switches secured to and operable between the frame and the carriage.
Claim 2
Dependent Claim
152 words
An X-ray diagnostic apparatus for urological examinations including an upright column, a frame secured to and vertically movable on the column, a table plate secured as a cantilever to the frame and movable transversely and longitudinally thereon, and an X-ray source secured to the column above the table plate and an image intensifier rigidly secured to the frame below the table plate and aligned with said source and further comprising a cassette carriage movable longitudinally and transversely within the table plate, electric motor means for moving said table plate and carriage respectively, first control means for automatically actuating said motor means to move the carriage between preselected positions, and second control means for partially reversing said carriage movement when the carriage overtravels one of said positions, said first and second control means comprising electric switches and cam means for actuating the switches secured to and operable between the frame and the carriage.
Claim 3
Dependent Claim
54 words
Apparatus as defined in claim 1, further comprising a film proximity diaphragm movable within said table plate above the cassette carriage, the diaphragm including slide means for variably defining an X-ray aperture, and third control means carried by the frame for engaging and moving said slide means to align the aperture and X-ray source.
Claim 4
Dependent Claim
58 words
A program control network for use in an apparatus as claimed in claim 2 characterized in that when the diaphragm is moved into the path of the rays, it acts upon the first and second control means for the frame-dependent disposition of the cassette carriage so that the exposure parts enter consecutively into the path of the rays.
Claim 5
Dependent Claim
41 words
An examination apparatus as claimed in claim 1 characterized in that the cassette is moved for exposure over the image iNtensifier only to an extent such that the lower cassette edge substantially coincides with the lower edge of the image intensifier.
