Abstract: A three-dimensional ultrasound imaging system includes an ultrasound probe to direct ultrasound waves to and to receive reflected ultrasound waves from a target volume of a subject under examination. The ultrasound probe is swept over the target volume along a linear scanning path and the reflected ultrasound waves are conveyed to a computer wherein successive two-dimensional images of the target volume are digitized. The digitized two-dimensional images can be used to generate a three-dimensional image with virtually no delay. A user interface allows a user to manipulate the displayed image. Specifically, the entire displayed image may be rotated about an arbitrary axis, a surface of the displayed image may be translated to provide different cross-sectional views of the image and a selected surface of the displayed image may be rotated about an arbitrary axis. All of these manipulations can be achieved via a single graphical input device such as a mouse connected to the computer.

Abstract: A reception signal containing phase information and amplitude information is obtained by scanning a cross section of a subject with an ultrasonic wave. An ultrasonic image is formed on the basis of the reception signal and displayed. A noise component is filtered from reception signals at respective points in the cross section. The reception signals, which have not been non-linear processed, i.e., have not been subjected to an image forming process, are filtered. Therefore, the suppression effect of suppressing an image of a portion which moves at a relatively low speed and the emphasis effect of emphasizing an image a portion which moves at a relatively high speed can be improved as compared to the conventional art in which an ultrasonic image after non-linear process is filtered.

Abstract: An ultrasonic inspection and imaging instrument scans an object under examination, the object having an inspection plane at a predetermined depth, in the direction slanted to the depth (slant scanning), in such a way as to cause rectilinear scanning as viewed from the plane. Measured data on a peak value corresponding to each measurement point obtained from the slant scanning are displayed in the form of a picture on the screen of a display relative to each measurement point. The image displayed on the picturee at that time is most clearly demonstrated, provided an image portion in the vicinity of a test portion corresponding to a test surface is brought into focus in the depth direction. An operator selects the image portion clearly indicated out of the picture displayed on the display, and inputs the position of the image thereon to an input unit, whereby an image processor bases the positional information about the display data thus fed and the relevant information indicating the positional relationship in the depth direction on obtaining the position of the probe in the depth direction when the measured value resulting from the image is collected. The image processor positions the probe there, so that the probe is automatically focused on the test surface.

Abstract: An ultrasonic visualization system for investigating human tissue structures, comprising pulse generator, power supply, pulse trigger, one transducer which transmits ultrasonic pulses, four transducers, arranged at 90* angles around the center transmitter, which receive reflected echoes, video amplifier and display tube. The output pulses of each pair of receivers 180* apart are connected through time coincidence circuitry to detect echoes originating only at the axis of the ultrasonic beam and to reject multiple reflection echoes, thus echograms of high resolution are obtained.

Abstract: A method, apparatus and system for locating external apparatus mounted to a tubular in a wellbore. The identification of apparatus, such as cable clamps, enables other tools in the string to operate more precisely. A computer model is used to locate the apparatus from acoustic images, which images are acquired using a downhole device having an acoustic sensor or acoustic array. The model may be a classifier, which may be machine trained to classify whether an apparatus is present, its location and its orientation. Automating this locating enables very long wellbores to be processed quickly.

Abstract: Acquisition settings for elasticity imaging are controlled based on detected motion. Rather than rely solely on user settings, one or more acquisition parameters are automatically set based on the detected motion. For example, the settings provide for a more rapid frame rate with less resolution in elasticity imaging for times associated with greater motion and for less rapid frame rate with greater resolution for times associated with lesser motion.
