Claims
- 1. An apparatus for recording X-ray images comprising:
- a panel-like X-ray recording device comprising:
- a first electrode transparent to X-ray radiation;
- a first photoconductive layer sensitive to X-ray radiation disposed beneath said first electrode;
- a second photoconductive layer sensitive to visible light disposed beneath said first photoconductive layer;
- a second electrode transparent to visible light disposed beneath said second photoconductive layer; and
- a cassette for removably installing and housing said X-ray recording device, said cassette comprising:
- a first wall transparent to X-ray radiation facing said first electrode;
- a second wall transparent to visible light disposed parallel and opposite said first wall and facing said second electrode; and
- connecting means for providing an electrical potential between said first and second electrodes.
- 2. The apparatus according to claim 1, wherein said cassette further comprises an electroluminescent panel disposed on said second wall for uniformly emitting light over said second photoconductive layer.
- 3. The apparatus according to claim 1, wherein said X-ray recording device further comprises a first isolating layer transparent to visible light disposed between said first electrode and said first photoconductive layer.
- 4. The apparatus according to claim 1, wherein said X-ray recording device further comprises a second isolating layer transparent to visible light disposed between said second electrode and said second photoconductive layer.
- 5. The apparatus according to claim 1, further comprising a DC power supply and a resistor connected in series between said first and second electrodes for providing said electrical potential.
- 6. The apparatus according to claim 1, further comprising an opaque layer disposed between said first and second photoconductive layers.
- 7. The apparatus according to claim 6, wherein said opaque layer is a layer of closely located micro-dots.
- 8. The apparatus according to claim 7, wherein said micro-dots are bismuth micro-dots.
- 9. The apparatus according to claim 1, wherein said second photoconductive layer comprises an organic photoconductor.
- 10. The apparatus according to claim 9, wherein the mass fraction of said organic photoconductor is at least 50%.
- 11. The apparatus according to claim 1, wherein said first photoconductive layer comprises a photoconductor having a mass fraction of at least 50%.
- 12. The apparatus according to claim 11, wherein said photoconductor includes zinc.
- 13. The apparatus according to claim 1, wherein said first photoconductive layer comprises thallous sulfide.
- 14. The apparatus according to claim 1, wherein said first photoconductive layer comprises an element having an atomic number greater than or equal to 30.
