  • Publication number: 20050023474
    Abstract: An improved method of, and apparatus for, nuclear imaging takes advantage of the ability to determine the depth of gamma ray/electron interaction within a semiconducting gamma ray detector to determine the (most highly probable) location of the first gamma ray/electron interaction within the detector. Lines of interaction constructed between opposing detector arrays, extending between the location of the first gamma ray/electron interaction in each detector associated with the coincident detection of gamma radiation, permits a positron-emitting object of interest to be imaged according to protocols known in the art, but with better spatial resolution than previously believed to have been known.

  • Publication number: 20040085715
    Abstract: A particular orientation of a control panel and an accessory device provides ergonomic benefits to an operator. A user control is mounted on a corner of the stand. The user interface of an accessory device is mounted at about a 45° angle to the control panel on one side of the stand. User tools, such as a transducer connector, are also mounted at about a 45° angle to the control panel, such as mounted on a different side of the stand adjacent to the control panel. Convenient access is provided to all of the control panel, the user interface of the accessory device, and the user tools. Additional leg room is also provided due to the angle of the stand relative to the user position in front of the control panel. The ultrasound system or other data system with this orientation of components allows ergonomic use of the system in a more confined space.

  • Patent number: 6730033
    Abstract: A two-dimensional array allows rapid three-dimensional ultrasound scanning. A high volume-per-second scan rate using a limited number of system channels (e.g. 192, 256 or other number of channels) is provided by a transducer array without beamforming circuitry in the probe. A fan beam of acoustic energy is transmitted along a scan plane from transducer elements that extend lengthwise over a substantial portion of the lateral aperture. Rows of these long transmit elements are provided along the elevation aperture for electronic steering of the fan beam in the elevation dimension. One or more rows of smaller receive elements are used for forming beams each representing a scan line along the lateral dimension in response to each transmission of a fan beam. Elevation resolution is provided primarily from the elevationally spaced transmit elements and partially from two or more rows of laterally spaced receive elements. The lateral resolution is responsive to the lateral spacing of the receive elements.

  • Publication number: 20030146935
    Abstract: A system and a method are described for providing a graphical user interface display with a conspicuous image element. In one example, a particular image element is first identified. Predetermined rules are then applied to ensure that the particular image element in a first window in a displayable image has a unique user visible display attribute absent from other image elements in the first window. Predetermined rules are also applied to ensure that the unique display attribute is absent from other image elements in any other window concurrently displayed in the displayed image. The particular image element is then enabled to be responsive to user selection.

  • Patent number: 6574491
    Abstract: A system for detecting a physiological parameter from a physiological signal, includes a source of the physiological signal. Circuitry, coupled to the signal source, detects spectral peaks in the physiological signal. Calculating circuitry, coupled to the spectral peak detecting circuitry, calculates a parameter value corresponding to each detected spectral peak. Weighting circuitry, coupled to the calculating circuitry and the spectral peak detecting circuit, assigns a weight to each peak according to a feature of a signal and the parameter value corresponding to that peak. Circuitry, coupled to the weighting circuitry, selects the peak according to a predetermined criterion. Output circuitry, coupled to the selecting circuitry and the calculating circuitry, then generates the parameter value corresponding to the selected peak.

  • Publication number: 20030055308
    Abstract: An ultrasonic imaging array has two independent, interleaved linear subarrays occupying a common array face. The subarrays are independently steerable and focusable in different imaging planes. The subelements making up the elements in of the subarrays is preferably quadrilateral. Adjacent subelements in each element are electrically connected via an interconnect portion such that the interconnect portion connecting each pair of adjacent subelements in each element is substantially linear and is aligned with the diagonals of the adjacent subelements. A preferred acoustic lens is curved in both azimuth and elevation directions, whereby the subarrays are independently focusable. By transmitting in one plane and simultaneously receiving in a different, orthogonal plane, a system including the array can image a 3-D region of interest (ROI). In a volumetric embodiment of the invention two orthogonal B-mode images of a structure within the ROI are displayed simultaneously.

  • Publication number: 20020167533
    Abstract: A method and system for displaying an image associated with an extended field of view is provided. One image comprises a compounded sub-set of the extended field of view. Other images may include an extended field of view image or an image absent compounding from the extended field of view image. The compounded sub-set image is associated with reduced noise as compared to the image absent compounding and more closely resembles an area of the extended field of view image. Where plurality of images are associated with a rotated transducer or scan planes or where a sector or Vector® scan pattern is used, the compounded sub-set provides spatial compounding associated with different angles of incidence to the region of interest, increasing speckle reduction.

  • Patent number: 6468218
    Abstract: A 3-D region of interest (ROI) of a body is imaged, preferably using an ultrasound transducer. The intensity of an echo signal from each of a pattern of pixels within the ROI is measured and stored. The pixels are then grouped into pixel blocks, and the intensity values for the pixels in each sequentially selected current block are compiled in a current histogram. Each current histogram is compared with a reference histogram that corresponds to the distribution of echo signal intensities in a known region of speckle. A structure likelihood value is then computed based on the comparison, where the structure likelihood value indicates how likely it is that the current block corresponds to a structure of interest as opposed to noise. The intensity value for any pixel likely to be noise is preferably scaled down. The scaled intensity values are then projected, preferably using a maximum intensity projection, onto a 2-D display plane, a representation of which is then displayed for a user to see.
