Arrangement for contact-free measurement of electro-radiographic recording methods
1984
In an exemplary embodiment, an electrical charge image is scanned by a matrix of integrated MOS components with a floating gate (or a switched floating gate), functioning as a matrix of potential sensors, to produce an image signal for display on a video screen. A minimum field effect transistor with source-follower circuitry is preferably employed as the potential sensor; the sensor outputs are linked to a shift register. The new component is suitable for employment for potential measurements in X-ray diagnostics.
