PATTERN SHAPING DEVICE AND DENTAL X-RAY APPARATUS INCORPORATING PATTERN SHAPING DEVICE Russian patent published in 2002 - IPC

Abstract RU 2190935 C2

FIELD: solid-state pattern shapers sensing detector roentgen rays. SUBSTANCE: prior to exposing object to X-ray source charges accumulated in charge-coupled device components are read out of two or more lines to register wherein they are summed up to obtain relatively high output signal. Then output signal is amplified and applied to limiter. Initialization of X-radiation is detected by rise of signal applied to limiter above reference level. EFFECT: improved design best suited to dental diagnostics by roentgen rays. 8 cl, 1 dwg
