Abstract
A portable, self-contained, electronic radioscopic imaging system uses a pulsed X-ray source, a remote X-ray sensor, and a self-contained, display and controller unit to produce, store, and/or display digital radioscopic images of an object under investigation. The pulsed X-ray source transmits a burst of narrow pulses of X-rays at the object being investigated at a low repetition rate. The X-ray sensor utilizes an X-ray scintillating screen in combination with either an integrating CCD camera, or an active matrix of thin film transistors and sample-and-hold photodiodes, to produce an integrated signal representative of the accumulated number of flashes of radiation that are sensed in a given pixel area of the scintillating screen. The self-contained display and controller unit utilizes digital signal processing within an enhanced portable computer, including a flat solid state display panel and associated drive circuitry, in order to display the full dynamic range and resolution of the sensor.
