Abstract
A method for providing X-ray image data signals corresponding to a selected portion of a two-dimensional image at an enhanced image resolution. During selective exposure of an X-ray receptor to X-ray radiation corresponding to the subject image, image pixel data corresponding to the region of interest (used pixels) are read out with normal pixel data pixel discharge times and at the normal pixel data rate, while image pixel data corresponding to the region not of interest (unused pixels) are read out also with normal pixel data pixel discharge times and at either the normal pixel data rate or an increased pixel data rate. During such pixel data readout intervals, the X-ray radiation exposure can be continuous or selectively pulsed.
