Claim 1
Independent Claim
208 words
An image transducer tube responsive to X-rays, comprising: an evacuated envelope having an entrance end transparent to incident X-rays; a luminary receiving unit in said envelope disposed adjacent said entrance end for irradiation by said X-rays, said receiving unit including a radiation-permeable base adjacent said entrance end and a radiation permeable fluorescent layer spaced from said base and said entrance end with an intermediate radiation-permeable conductive layer disposed between said base and said fluorescent layer in a plane with said entrance end, said conductive layer being connected in a series arrangement to a source of unipotential current; relay means disposed in said series arrangement to serve as a valve to electronically gate transmission of said unipotential current so that a pulsed effect is released, said relay means being activated by said X-rays; and an image intensifier structure disposed in said envelope confronting said fluorescent layer, said pulsed effect activating said image intensifier structure for receiving a fluorescent image from said fluorescent layer, said fluorescent image resulting from both emitted light by said fluorescent layer of said unit and penetrating action of said X-rays through said unit, said image intensifier structure including luminescent means to produce an intensified light image resulting from said fluorescent image and said penetrating Xrays.
Claim 2
Dependent Claim
208 words
An image transducer tube responsive to X-rays, comprising: an evacuated envelope having an entrance end transparent to incident X-rays; a luminary receiving unit in said envelope disposed adjacent said entrance end for irradiation by said X-rays, said receiving unit including a radiation-permeable base adjacent said entrance end and a radiation permeable fluorescent layer spaced from said base and said entrance end with an intermediate radiation-permeable conductive layer disposed between said base and said fluorescent layer in a plane with said entrance end, said conductive layer being connected in a series arrangement to a source of unipotential current; relay means disposed in said series arrangement to serve as a valve to electronically gate transmission of said unipotential current so that a pulsed effect is released, said relay means being activated by said X-rays; and an image intensifier structure disposed in said envelope confronting said fluorescent layer, said pulsed effect activating said image intensifier structure for receiving a fluorescent image from said fluorescent layer, said fluorescent image resulting from both emitted light by said fluorescent layer of said unit and penetrating action of said X-rays through said unit, said image intensifier structure including luminescent means to produce an intensified light image resulting from said fluorescent image and said penetrating Xrays.
Claim 3
Dependent Claim
37 words
An image transducer tube as defined in claim 1, wherein said tube further comprises a receiving target disposed in said envelope for storing energy of said intensified light image and beam-generating means for periodically scanning said target.
Claim 4
Dependent Claim
112 words
An image transducer tube as defined in claim 1, wherein said image intensifier structure comprises a photoconductive layer proximal to said receiving unit, an adjoining barrier layer opaque to said light rays and an adjoining photo-electro-luminescent layer defining said luminescent means in a planar array sandwiched with said photoconductive layer and said photo-electro-luminescent layer having an opaque layer intermediate between them to prevent light spreading in a transverse direction, said planar array being excited jointly by said penetrating X-rays from said entrance end and said fluorescent image from said receiving unit, and further said planar array being activated concurrent with said X-rays penetrating therethrough by an electric field applied to said array.
Claim 5
Dependent Claim
51 words
An image transducer tube as defined in claim 3, wherein said image intensifier structure further comprises a pair of conductive layers bracketing said photo-conductive and photo-electro-luminescent layers, and a further source of voltage including a variable potential connected across said conductive layers to stimulate electro-luminescence of said device by ionizing radiation.
Claim 6
Dependent Claim
50 words
An image transducer tube as defined in claim 1, wherein said tube further comprises an output storage target for storage of photonic image from said image intensifier structure, said storage target including a translucent base plate, an intermediate conductive signal plate, and a storage layer having a long-time storage function.
Claim 7
Dependent Claim
40 words
An image transducer tube as defined in claim 5, wherein said base plate of said storage target is provided with a lead glass material impermeable to ionizing radiation emitted to said target from said entrance end of said evacuated envelope.
Claim 8
Dependent Claim
27 words
An image intensifier device as defined in claim 2, wherein said receiving target includes a signal layer of spongy selenium and a storage layer of cadmium selenide.
