    摘要: The present invention provides for x-ray imaging and ultrasound imaging of a body region of interest in a spatially correlatable manner. The resultant x-ray and ultrasound images may be combinatively employed to provide three-dimensional information regarding a location of interest within the body, and is particularly apt for use in the analysis/biopsy of potential lesions and suspicious masses in a female breast. The invention provides for direct body contact by an ultrasound imaging head, as well as targeted ultrasound imaging of a selected portion of the region from which x-ray images are obtained. A user interface system facilitates various procedures including ultrasound guided needle biopsy procedures.

    摘要: A mirror made of a synthetic plastics material in the shape of a shallow tray having a base which is metallized on its internal or external surface. The shallow tray has a rim integral with the periphery of the base. The shape of the cross-section of the rim enables the peripheral edge at the front of the mirror to be convexly rounded to a required radius greater than the thickness of the base. The shape of the cross-section of the rim also serves to hold the base from distortion and so maintains the optical properties of the mirror.

    摘要: An impedance matching system and a network for impedance matching at a driver circuit output for high frequency input-output devices. The impedance matching network comprises an adjustable-length transmission line having a length adjusted in proportion to the magnitude of transients on the driver circuit output and an input impedance, which is purely reactive, and is a function of its length. The purpose of the adjustable-length transmission line is to reduce transient voltages by providing a matching impedance for the reactive component of the impedance of the receiver circuit to the driver circuit. In the preferred embodiment, the impedance matching network comprises two parallel conductive lines formed on the system card, shorted by a movable stub, and connected in parallel to the driver circuit. Optionally, the impedance matching network further comprises a control circuit which detects overshoots and undershoots on the driver circuit output and provides a control current proportional to the magnitude of overshoots and undershoots to an electromagnetic adjustment mechanism which provides a linear adjustment to the moveable stub proportional to the control current.

    摘要: An impedance matching system and a network for automatic impedance matching at a driver circuit output for high frequency input-output devices. The impedance matching network comprises a control circuit which varies a control voltage proportionally to the frequency of voltage transients that occur on the driver circuit output, an adjustment mechanism which provides a linear motion proportional to the control voltage, and an adjustable length transmission line whose length is adjusted in proportion to the frequency of voltage transients on the driver circuit output and whose impedance, which is purely reactive, is proportional to its length. The purpose of the adjustable length transmission line is to reduce transient voltages by providing a matching impedance for the reactive component of the impedance of the receiver network to the driver circuit. In the preferred embodiment, the impedance matching network is manufactured on the same chip as the driver circuit.
