Abstract
An x-ray system () comprises a gantry () on which an x-ray source () and an x-ray detector () are mounted. A control unit () comprises means () for effectuating a wiggling motion of the gantry, wherein an axis () connecting the x-ray source and the x-ray detector traces a surface () of a cone (). The x-ray source and the x-ray detector have a fixed position with respect to the axis. The control unit comprises means () for acquiring a series of x-ray images during the wiggling motion of the gantry. An object recognition unit () detects an object () appearing in the series of x-ray images to obtain a tracked path. A depth estimation unit () uses the tracked path for estimating a depth parameter indicative of a position of the object in a direction substantially parallel to the axis ().
