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. | 01-22-2009 |
20090024029 | ULTRASOUND DIAGNOSTIC APPARATUS - 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. Binarization processing and three-dimensional labeling processing are applied to velocity volume data, to thereby generate three-dimensional mask data. At this time, because a bloodstream object has a larger volume size than a noise object, this difference in volume size is utilized to discriminate between a bloodstream portion and a noise portion. Bloodstream volume data are then generated from the velocity volume data and by reference to the three-dimensional mask data. Then, a three-dimensional bloodstream image is formed by reference to the bloodstream volume data. | 01-22-2009 |

An interpolation coefficient memory stores an interpolation coefficient which is used for the interpolation process. When the parameter calculating unit calculates, for each parameter, parameter values of the times from telediastole to the telesystole, a region-of-interest setting unit sets, for each time, a three-dimensional region of interest in the three-dimensional data space based on the plurality of parameters. With this process, a three-dimensional region of interest which dynamically changes from the telediastole to the telesystole is set in the three-dimensional data space. | 01-08-2009 |

20080242982 | METHODS AND APPARATUS FOR ULTRASOUND IMAGING - Blood flow information is used to reduce noise manifest in blood vessel ultrasound B-mode images. A blood flow signal is obtained by a flow detector. After wall filtering, only the flow signal power in the blood vessel lumen remains, while signal power from stationary tissue region is suppressed. The flow signal component is used to calculate a flow component parameter that is used to generate a gain control signal α that reduces noise in a B-mode image. | 10-02-2008 |
20080242970 | LOAD APPARATUS - An oscillation arm moves in a seesaw fashion about an oscillation axis which is supported by a support rod and which serves as a fulcrum. A rotation arm and a pressurizer are provided on one end of the oscillation arm. One end of the rotation arm is rotatably attached to the oscillation arm, and a load weight is placed on the other end of the rotation arm. By rotating the rotation arm, the magnitude of a force to be applied by the load weight to the pressurizer is adjusted. More specifically, by displacing the load weight to a predetermined position by rotation and then causing the load weight to stop at this position, a static load corresponding to the rotation angle can be applied to the pressurizer. Further, by causing the load weight to perform rotational motion, the magnitude of the force to be applied to the pressurizer is periodically varied, so that a load which varies periodically can be applied to hard tissue. | 10-02-2008 |
