A component for introducing disturbances into the magnetic field of an asynchronous motor by altering a reluctance of the motor is disclosed. An asynchronous motor is provided that includes a stator having a plurality of windings that is configured to generate a rotating magnetic field when a current is provided to the plurality of windings. The asynchronous motor also includes a rotor positioned within the stator configured to rotate relative thereto responsive to the rotating magnetic field and a component separate from the stator and the rotor that is positioned within the rotating magnetic field, with the component being configured to alter a magnetic reluctance of the rotor so as create a disturbance in the rotating magnetic field.

A system and method for improved imaging of a subject through the use of low dose exposure aided positioning is provided. The subject is positioned in an X-ray imaging system and imaged with a low dose pre-shot X-ray exposure to verify the positioning of the subject. If the subject's positioning is acceptable, the subject is then imaged with a full dose X-ray exposure. If the subject's positioning is not acceptable, the subject is repositioned and re-imaged with a low dose pre-shot X-ray exposure until the subject's positioning is acceptable. The low dose pre-shot X-ray exposure may take the form of a low dose X-ray imaging sequence where the radiation dose is less than the radiation dose of a full dose X-ray exposure.

Methods and systems are provided for dual energy imaging. In one embodiment, a method for a dual energy imaging system comprises determining a first tube potential and a second tube potential according to a size of a subject, and controlling the dual energy imaging system with the first tube potential and the second tube potential to generate lower energy x-rays and higher energy x-rays respectively to image the subject. In this way, image quality may be increased while minimizing dose during dual energy imaging of a particular imaging subject.

A system and method for calibrating an X-ray tube is provided in which the X-ray tube includes an electronic storage medium associated with the X-ray tube on which calibration information for the X-ray tube is stored. The calibration information includes operating parameters for the focusing elements of the X-ray tube for desired focal spots, tolerance limits for variations in the focal spots and a number of gradient coefficient values corresponding to certain modulation transfer functions (MTF) for the X-ray tube that the imaging system can employ in an iterative manner to correct the operating parameters of the focusing elements to achieve the desired focal spot. This automatic iterative process significantly reduces the time required for the calibration of the X-ray tube. The system and method also employs scan sequencing to minimize the heat generated enabling the scans to be completed in a shorter amount of time than prior calibration processes.

An emitter for a cathode of an X-ray tube is provided that includes a shaped emitting surface. The emitting surface is shaped in a suitable process in order to enable the emitting surface to focus electron beams emitted from the emitting surface on a focal spot on a target of less than 1.0 mm without the need for any additional focusing elements in the X-ray tube.
