摘要： An electronic signal processing device which forms a compound image for any pulse-echo ultrasound imaging system using a two-dimensional array transducer. The processing device obtains the detected sum of a series of cross-shaped apertures within the transducer in order to form a spatial compound image with the output of each cross-shaped aperture consisting of the product of the output signals from the orthogonal arms of the cross.

摘要： Tissue signatures are obtained from first and second order statistics of an image texture to discriminate between different normal tissues and to detect abnormal conditions. These signatures describe intrinsic backscatter properties of the tissue imaged, and are used as the basis of an automatic tissue characterization algorithm. A device for on-line classifying of the texture of an image measures a total of four first and second order statistical properties of echo signals of a region of interest (ROI) selected by an operator, the echo signals being contained in an image memory. These can be used to obtain the tissue signatures, to detect low contrast lesions by machine, and to produce parametric images.

摘要： An acoustic pulse echo imaging system capable of producing an image of a three-dimensional object utilizing a two-dimensional display having perspective capabilities is described. In the system angular relationships of targets at all ranges are maintained for display. The system uses a two-dimensional transducer array of piezoelectric elements; the array is steered to assume transmit and receive orientations in both azimuth and elevation by producing (1) a directed transmit pulse and many similarly directed receive orientations or (2) a non-directed transmit pulse and many directed receive orientations. For each transmit pulse a parallel processing system produces several unique image points whose locations in the image correspond to the tangents of the angles of the receive orientations in the azimuth and elevation planes. The brightness of each image point is the weighted integral of the echo data received along each receive path. As an option, range discrimination capability is provided by means of a range dependent gain control, brightness shading as a function of range or a color display in which data originating from different ranges is displayed in different hues.

摘要： A modular sheet metal door structure consists of a plurality of upright modules of the same length which are fixedly connected to one another and have coplanar main webs forming one face of the door. A sheet metal sheath fixedly connected to side webs of the modules forms the other face of the door and has upright marginal portions which closely embrace the modules to form upright door sides. Identical sheet metal header means are fixedly secured to the ends of the modules to provide the ends of the door, and the header means are constructed to be detachably connected to stems by which the door may be suspended from track-mounted carriages for sidewise movement with either end of the door up.
