Abstract
The disclosure is directed to an improved method and apparatus for obtaining a processed image of a body. In accordance with the disclosed method, a bolus of contrast medium is injected into the body, and the body is irradiated. Radiation which passes through the body is detected and converted into an electronic video signal. The generated video signal is then filtered with a filter function having a temporal frequency response that has a single bandpass peak at a temporal frequency substantially corresponding to the temporal frequency of the movement of the bolus of contrast material through a region of the body. The filtered signal can then be displayed and/or recorded.
