Apparatus and method to readout X-ray information in a phosphor layer

摘要

Sensors (10,11) are positioned at start and end of line (8) of phosphor sheet (1), along which light beam (3) moves. Beam passes sensors (10,11) respectively before and after scanning line, so that sensors collect light emitted by sheet at two reference times. Detector signal values (D) are deduced from signal (S) converted from collected light, to deduce picture values (B) from deduced values (D) between two reference times. An independent claim is also included for X-ray data reading apparatus.
