摘要： An x-ray source (32) for performing energy discrimination within an imaging system (10) includes a cathode-emitting device (82) emitting electrons and an anode (81) that has a target (80) whereupon the electrons impinge to generate an x-ray beam (93) with multiple x-ray quantity energy peaks (116 and 120). A method of performing energy discrimination in the imaging system (10) includes emitting the electrons. The x-ray beam (93) with the x-ray quantity energy peaks (116 and 120) is generated. The x-ray beam (93) is directed through an object (44) and is received. An x-ray image having multiple energy differentiable characteristics is generated in response to the x-ray beam (93).

摘要： A multi-functional endoscopic system, for use in electrosurgical applications, that includes an imaging endoscope that may be used in combination with various electrosurgical devices, all of which are sufficiently inexpensive to manufacture, such that the endoscope and electrosurgical devices are considered single use, disposable items. The multi-functional endoscopic system of the present invention is suitable for use with a variety of common electrosurgical devices that require electrical/electronic support in order to function. The electrical/electronic support for these electrosurgical devices (e.g., an electrosurgical generator and associated controls) is integrated with the operator console of the imaging endoscope of the multi-functional endoscopic system of the present invention, rather than provided as a separate device. In another embodiment of the invention, an imaging endoscope is provided that integrates or combines the functions of both an imaging endoscope and an electrosurgical device, which can be controlled by a single handheld controller.

摘要： Systems and methods for reducing temperature variation during burn-in testing. In one embodiment, power consumed by an integrated circuit under test is measured. An ambient temperature associated with the integrated circuit is measured. A desired junction temperature of the integrated circuit is achieved by adjusting a body bias voltage of the integrated circuit. By controlling temperature of individual integrated circuits, temperature variation during burn-in testing can be reduced.

摘要： The present invention provides a CT detector module with cell summing in the Z-direction and cell staggering in the X-direction. The present invention also provides a method for implementing the present invention by simply combining the cells in the Z-direction. The staggering of the cells in the Z-axis improves the signal sampling in the Z-direction without changing either the X-axis or Y-axis resolution. In effect, this provides spatial resolution in the Z-direction.
