摘要： An ultrasonic imaging method capable of increasing density of sampling points in accordance with depths within an object. In this method, a predetermined area contained in the object is divided into at least a first area located most shallowly and a second area located deeper. The method includes the steps of: (a) transmitting and receiving ultrasonic waves focused in one focus direction within the first area to take samples of an ultrasonic image at a plurality of points in the focus direction, and changing the focus direction to scan the first area; (b) sequentially transmitting ultrasonic waves focused in respective focus directions within the second area in a predetermined time period, thereafter receiving ultrasonic waves reflected from the respective focus directions to take samples of the ultrasonic image at a plurality of points in the respective focus directions.

摘要： The axis of rotational transducer array scans, because of imperfect transducer array assembly, may have two orthogonal offsets relative to the geometric center of the transducer array. Without knowledge of these offsets, it is not possible to convert rotational transducer scan data into a rectilinear (Euclidean) coordinate system, as is necessary for three-dimensional processing. Using spatial coherency between appropriate scan lines in different rotational transducer scans, the horizontal and vertical rotational offsets are calculated. These offsets are then utilized in converting the data to a rectilinear coordinate system for three-dimensional processing.

摘要： A method and apparatus are provided for interpolating image lines from ultrasonically obtained scanlines of an image region. The interpolated lines are preferably formed one-quarter and three-quarters of the distance between each pair of received scanlines by combining weighted samples of the adjacent scanlines in proportion to their distances from the interpolated lines. The received scanlines are preferably formed by a beamformer which samples the received lines at quadrature phases of the scanhead center frequency and filters the samples by combining successive samples of a related phase. The image lines are scan converted by computing a grid of weighted values between each pair of image lines, and using the closest value for each pixel in the ultrasound image.

摘要： An ultrasound system creates ultrasound images at faster frame rate by eliminating ultrasonic transmissions along every beam line. Preferably, ultrasound images are created by alternately transmitting ultrasonic signals on the even and odd transmit beam lines. Parallel beam forming is used where transmissions along a single transmit beam line create echo signals on a pair of receive beam lines. To eliminate the artifact caused by the round-trip beam line sensitivities, echo signals created in response to transmissions along the even transmit beam lines are averaged with echo signals created in response to transmissions on the odd transmit beam lines. The averaged echo signals are used to create an ultrasound image without artifacts.

摘要： A method and apparatus for ultrasound imaging utilize tissue-centered scan conversion to compensate for transducer motion. A reference point, typically located in a region of interest, is selected. An ultrasound probe is positioned at a selected probe position and orientation relative to the region of interest. The region of interest is ultrasonically scanned, and echo signals representative of ultrasound echoes received from the region of interest are generated. The echo signals are referenced to the probe position and orientation. The probe position and orientation relative to the reference point are determined, typically by a sensing device. The echo signals and the probe position and orientation are transformed to image signals for display. The process is repeated for different probe positions and orientations to obtain a plurality of images. Each of the images is referenced to the selected reference point as the probe position and orientation changes, thereby compensating for transducer motion.
