Abstract
Abstract An X-ray examination device having an imaging area which is less than the length of an object to be imaged, acquires a series of high-resolution input images at selected different positions which overlap along the length of the object. The high-resolution images are processed in accordance with first and second methods for later application to a display device. The first method creates a low-resolution composite image for display which is simutaneously representative of a plurality of the high-resolution acquired images, and the second method determines portions of each of the acquired images which are to be deleted and provides to the display the series of high-resolution images in a scroll fashion with the predetermined portions deleted from the adjacent images. The user has control means for controllably indicating a position (region of interest) on the display for causing the display to provide a high-resolution image which is centered about the region of interest. Additionally, the control means provides control signals to a gantry control apparatus for centering the X-ray examination device over the region of interest. Finally, a processing method and apparatus is provided for displaying the scrolled images in a visually pleasing manner wherein the portions of adjacent images to be deleted is determined by providing continuity for identifiable features of the high-resolution images.
