Abstract
A multi-mode acquisition x-ray imaging system (A) provides a unified apparatus and method to acquire valid x-ray video images including the last image of a run, and to display these images flicker-free on an image monitor (50). A beam blanking signal (54) synchronizes operation of a TV camera (48) and TV camera controller (56), so all image data or frames acquired in any acquisition mode including one having a pulse exposure rate or an asynchronous pulse exposure rate is acquired and processed by a digital imaging system (40). The image data is stored in a dual buffered storage (76) which alternatingly connects a first buffer (80a) and a second buffer (80b) to the image monitor (50). When the exposure rate is changed, transition logic (84) determines whether images, exposed during the transition to another exposure rate are under or overexposed.
