摘要： An acoustic matching device has a water bag (64) that contains water and a water bag support frame (66) that sandwiches and supports the water bag on the left and right sides of the knee and curves along the knee cap. The water bag becomes a plate shape curved along the shape of the water bag support frame, which touches the knee cap and fits the unevenness of the knee. When an ultrasonic probe is moved along the knee cap, the acoustic matching between the knee cap and the ultrasonic probe is obtained.

摘要： An ultrasonic volume data processing device which forms a three-dimensional image of a target tissue in a living body is provided. A range in which a rendering process is applied is limited by a three-dimensional region of interest (3D-ROI). The three-dimensional region of interest has a clipping plane as a rendering start surface. A shape of the clipping plane can be deformed into a convex shape or a concave shape by a user operation, and the clipping plane may be freely inclined in two-dimensional directions. With this configuration, for example, the clipping plane can be suitably positioned in a gap between a face of a fetus and a placenta. When the curved clipping plane is used, a striped pattern noise tends to be formed in the three-dimensional image. In order to resolve or reduce the striped pattern noise, a special voxel calculation is applied to a final voxel of each ray in the voxel calculation for each ray.

摘要： In FIG. 2 (A), a reception beam (102) is formed using a weighting function (112). A position of a peak of the weighting function (112) is set at the position of the reception beam (102). A reception beam (104) is formed using a weighting function (114), and a position of a peak of the weighting function (114) is set at the position of the reception beam (104). A reception beam (106) is formed using a weighting function (116) and a position of a peak of the weighting function (116) is set at a position of the reception beam (106). In this manner, the positions of the peaks of the weighting functions (112, 114, 116) are shifted in the receive aperture, to follow movements of the reception beams (102, 104, 106) caused by electrical scanning.

摘要： A radiation measuring device capable of identifying the incident direction of a radiation ray and energy (segmentation). The directivity characteristics of a plurality of detectors are different from each other. A plurality of energy segmentations are set respectively for a plurality of spectra corresponding to a plurality of detectors, and actual measurement ratio information (a plurality of actual measurement counting ratios) expressing the mutual ratio between integrated counting values for each energy segmentation is computed. The actual measurement ratio information is checked against a plurality of response functions, and, when the compatibility relation between specific actual measurement ratio information and specific theoretical ratio information is found, the incident direction of a radiation ray and an energy segmentation are identified based on that relation.

摘要： In an ultrasound receive beamformer signals from two or more aperture elements are multiplexed at the input of each beamformer channel, stored in different portions of a delay memory, delayed and apodized in a time-multiplexed fashion, demultiplexed at the output of the channel, and summed in different summation units running at an upsampled rate. The partial sums are then time-aligned, summed to produce the total upsampled beam sum, filtered and decimated in an interpolation filter to produce the beamformed signal.

摘要： An ultrasound diagnostic apparatus which forms a three-dimensional bloodstream image by reference to volume data obtained from a three-dimensional space within a living organism. A modified maximum value detection method is applied along each ray. Search of a maximum value is sequentially executed from a search start point, and at a time point when a predetermined termination condition is satisfied, a maximum value which is being detected at this time point is regarded as a specific maximum value. The specific maximum value is then converted into a pixel value. The specific maximum value is a first peak and is specified even if a higher peak exists after the first peak. A three-dimensional bloodstream image is formed by a plurality of pixel values. In a portion of the three-dimensional bloodstream image in which two bloodstreams cross each other, a bloodstream located on the front side is preferentially displayed.

摘要： A transmission wave corresponding to an FM continuous wave having been subjected to an FM modulation processing is transmitted from a transmitting transducer 10. A pre-amplifier 16 generates a reception RF signal and outputs the reception RF signal to a receiving mixer 30. The receiving mixer 30 applies orthogonal detection to the reception RF signal to generate a complex signal. A reference signal supplied to each mixer in the receiving mixer 30 is generated based on an FM continuous wave output from an FM modulator 20. The FM continuous wave output from the FM modulator 20 is delayed by a delay circuit 25, and one signal is directly supplied to a mixer 32 whereas the other signal is supplied to a mixer 34 via a π/2 shift circuit 26. The delay circuit 25 applies a delay processing in accordance with a depth of a target position within a living organism to the FM continuous wave. As a result, Doppler information from the target position can be selectively extracted by a Doppler information analyzing section 44.
