摘要： A method for asynchronous operation of a rotary anode of an x-ray emitter, where a torque is exerted onto the rotary anode by an electromagnetic alternating field of a stator with a first frequency is provided. The method includes increasing the first frequency to a second frequency. The second frequency is a whole number multiple of an x-ray trigger frequency. The method also includes simultaneously changing an output of the alternating field such that a rotational frequency of the rotary anode remains unchanged.

摘要： The present invention relates to an X-ray imaging apparatus, and more particularly, to an X-ray imaging apparatus in which a condenser is charged with low battery voltage, and the charged voltage of the condenser, or the sum voltage of the output voltage of the battery serially connected to the condenser and the charged voltage of the condenser is used as X-ray generating power. The X-ray imaging apparatus according to the present invention is configured such that the battery power and the condenser power are serially connected to provide power for operating the X-ray imaging apparatus, thus generating power for operating the X-ray imaging apparatus from the low battery power, and obtaining a lightweight and less bulky X-ray imaging apparatus. Further, the X-ray imaging apparatus according to the present invention senses the charged voltage of the condenser unit, and cuts off power being applied to the condenser charging unit from the battery when it is determined that the charging of the condenser unit is completed, thus reducing the power consumption of the battery.

The scanner may further include a conveyor arranged to convey an object through the imaging volume in a scan direction, and may also include at least one processor arranged to process the detector signals to produce an image data set defining an image of the object. The image may have a resolution in the scan direction that is at least 90% as high as in one direction, and in some cases two directions, orthogonal to the scan direction.
