摘要：
One X-ray tube is described comprising component is used to increase X ray image clarity, including focus size and focal position under the conditions of focusing dot characteristics existing for the mobile x-ray source by modification. A static focal spot is moved into the direction that the movement with x-ray source is opposite in the first configuration, so that an effective focal spot position is being substantially fixed during tomosynthesis exposure relative to the space of one of imaging object and/or detector. In the second configuration, increase the size of static focal spot, the resulting increase in tube current reduces time for exposure and adjoint blur effect. Method may be used alone or in combination Such as it is bigger with one, an X-ray tube of movable static focal spot will lead to a kind of system for making full use of X-ray tube generator, provide the fuzzy of high quality image reduction and due to the reduction in the time for exposure, can more quickly scan patient.
