Abstract
The present disclosure discloses an afterglow detection device and an afterglow detection method. The afterglow detection device comprises: an X-ray tube for emitting an X-ray beam; a first reading circuit for receiving a first detected signal from a to-be-detected detector to form and output a first measurement signal according to the first detected signal, the to-be-detected detector being connected to the first reading circuit and disposed on a beam-out side of the X-ray tube to receive radiation of the X-ray beam and outputting the first detected signal to the first reading circuit at the time of detection; a residual ray detector disposed on a beam-out side of the X-ray tube; a second reading circuit connected to the residual ray detector for receiving a second detected signal from the residual ray detector to form and output a second measurement signal according to the second detected signal.
