Title (EN) BEAM DETECTION AND FILTERING NOISE
(FR) DÉTECTION DE FAISCEAU ET BRUIT DE FILTRAGE
Abstract:
(EN) A digital radiographic detector outputs positive read out signals that may oscillate. The presence of negative going portions of the read out signals may be used to determine that the detected positive signals are a result of noise, while an absence of the negative going portions may be used to determine that x- rays are impacting the detector.
(FR) La présente invention concerne un détecteur radiographique numérique qui émet des signaux de lecture positifs qui peuvent osciller. La présence de parties négatives des signaux de lecture peut être utilisée pour déterminer que les signaux positifs détectés sont un résultat de bruit, alors que l'absence des parties négatives peut être utilisée pour déterminer que des rayons X sont incidents sur le détecteur.
