A fluoroscopic imaging apparatus is provided. The apparatus includes an
x-ray source for projecting x-rays through a subject. The x-ray source has
a voltage and a current associated therewith. The apparatus also includes
an x-ray detector for detecting radiation which has passed through the
subject and a monitor for displaying an image indicative of the detected
radiation. The image defines a field of view. In addition, the
fluoroscopic imaging apparatus includes an operator interface for
selecting a region of interest within the field of view. In response to
image data within the region of interest, an image of the region of
interest can thereafter be enhanced.
