Abstract
Abstract Closed-circuit TV fluoroscopic equipment, such as X-ray microscopes of reduced physical size and improved performance, in which X-ray source is enclosed in shielding capsule and a shielding chamber containing object to be X-rayed is positioned on an X-ray beam intercept path relative to a signal converter for adjustment of X-ray intensity and object-to-target distance.

Claim 1
Independent Claim
136 words
A closed-circuit-TV X-ray microscope, comprising; an X-ray source; a shielding capsule containing said X-ray source; a shielding object chamber having a common wall with said shielding capsule; an aperture in said wall for passing an X-ray beam from said X-ray source into said shielding object chamber; a converter for converting X-ray shadow images of an object located between said source and said converter into TV signals, said X-ray-TV converter and said object adapted to be positioned in said object chamber in the path of the X-ray beam and being movable along the axis thereof; and an enclosure permanently connected To said object chamber and extending through an aperture therein, said X-ray-TV converter being rigidly supported within said enclosure, said enclosure and the X-ray-TV converter supported therein being jointly movable through said aperture into said object chamber.
