Abstract

A completely portable, rugged camera for providing in real time, visual light images of extended objects emitting low energy X-ray and gamma-ray photons. Collimated radiation eminating from extended objects such as internal anatomical organ structures which have absorbed low dosages of radio-active isotopes, are filtered through a visible light shield, converted into visible light photons, and, alternatively magnified or demagnified while spatial orientation is maintained. The visible light photons are subsequently intensified, in one or more cascaded stages, through conversions into electrons, multiplied through micro-channel plate electron multipliers, and reconverted by a phosphor screen to visible light and provide a high spatial resolution visual light image either directly to a viewer or to a device such as an image recorder.
