Abstract
A medical X-ray imaging apparatus is provided, which comprises an X-ray source, an X-ray imaging device for detecting an image of X-rays having passed through a subject and a swivel member for-rotating the X-ray source and the X-ray imaging device around the subject. The X-ray imaging device comprises a CCD sensor for performing the TDI operation and a dosage sensor for detecting X-rays having passed. Dosage signal Y and transfer speed signal X corresponding to the frequency of a false vertical transfer clock are supplied to a divider, and control signal Z is outputted. When control signal Z is supplied to an X-ray control circuit via a delay circuit, the X-ray irradiation dosage of the X-ray source can be feedback-controlled properly.
