    摘要: A method for transferring heat away from an ultrasonic medical transducer having a face wherein heat is generated. The method is accomplished by positioning a heat sink behind the transducer face, securing the heat sink to a braided power cable, applying a heat conductive epoxy to the heat sink, and assembling a plastic housing around the heat sink. The transducer face is cooled by conductive heat transfer by transferring the heat into the heat sink, then transferring the heat into the epoxy, then transferring the heat into the power cable and the plastic housing before finally dissipating into the surrounding air.

    摘要: The train of echoes received in an ultrasound imaging system having an array of ultrasound transducers is shaped and/or focused by first and second programmable beam focusing modules (16-24) in a dynamic receive focus mode. The elemental ultrasound echo signals from a plurality of channels connected to the elements of the transducer array are selectively attenuated and/or phased shifted according to the programs prescribed for the focus zones and combined by each module. The combined echo signals are further processed in conventional fashion (34-38). The modules operates alternately. One module is being programmed, while the other module is combining the elemental echo signals for processing. Each beam focusing module comprises a delay line (56-60) having a plurality of input taps and a cross point switch (52) selectively connecting the channels to the input taps. The module is programmed by selectively closing the individual cross points of the cross point switch. Beam shaping i.e. apodizing, is accomplished by selectively attenuating the echoes (A,-A4$) prior to application to the input taps of the delay line in each module. The modules can be reconfigured to connect the modules in series in a composite focus mode.

    摘要: A foreground image is overlaid over a background image on a visual display. Specifically, an ultrasound signal is transmitted toward a target to be displayed in two dimensions. Echoes of the ultrasound signal are received from the target. Two-dimensional target data acquired from the received echoes are stored. The two-dimensional target data are presented on the visual display as a background image. Part of the target data are overlaid over the background image as a foreground image on the visual display. The size of the foreground image vis-a-vis the background image is changed by the user to permit better observation of an area of interest. Preferably, the size of the foreground image is changed without changing the area occupied by the foreground image on the visual display, which permits the invention to simulate the action of a magnifying glass. The user moves a cursor on the visual display to the center of an area of interest. The user then opens up a window about the cursor to define the length and width of the foreground image on the visual display, while observing the target data presented on the visual display. The user can then magnify the size of the foreground image centered on the cursor, chance the dimensions of the window, and/or change the location of the cursor to move the area of interest, without disturbing the background image.

    摘要: A curved array ultrasonic transducer is manufactured by cutting a flat transducer plate (12), which is attached to a flexible support plate (11), into a plurality of segments (14), the segments being hingedly attached by the support plate. The support plate is bent to a radius (FIG. 2) and the conductive traces in a flexible circuit board are electrically connected to the transducer plate segments (FIG. 4). The flexible circuit board, having a plurality of branches, is bent to a perpendicular position such that the traces in the plurality of branches become substantially aligned (FIG. 6). The traces exiting the branches are then electrically connected to a pin and socket connector device (FIG. 8).
