Abstract:
A method of creating a 3D X-ray dataset, in which successive depth plane information is obtained from a stereoscopic pair of X-ray images by successively subtracting the image information of one of the pair from the other of the pair when the pair is superimposed at one relative lateral superimposition so giving first depth plane information, moving the pair relative to one another by an amount equal to the minimum detectable parallax in a display for the images, again subtracting the image information of one of the pair from the other of the pair at said later superimposition so giving second depth plane information, and further subtracting the first depth plane information from the second depth plane information to provide the unique depth plane information at said one relative lateral superimposition, effecting said movement and subtractions as necessary to provide unique depth plane information for as many planes as required, said second depth plane information being used as said first depth plane information in a subsequent step and new second depth plane information being obtainable after said movement of the pair relative one another by an amount equal to the minimum detectable parallax in a display for the images.
