    摘要: Adaptive volume rendering is provided for medical diagnostic ultrasound. The opacity of B-mode data is set relative to the opacity of Doppler data. The opacities for the different types of data are set as a function of ray depth. For example, the opacity of B-mode data near a tissue border is set to be more opaque than for tissue away from the border, and the opacity for flow data near a flow border is set to be less opaque than for flow away from the border. An image is rendered using a rendering parameter set as a function of ray depth, B-mode information and Doppler information. Other processes for enhancing and/or using rendering may be used.

    摘要: Spatial relationships are conveyed in three-dimensional ultrasound imaging. To transition a volume rendering from one view to another view, the transition is animated, showing rotation. For example, the user examines one diagnostic view, but decides to examine another diagnostic view. Upon selection of the other diagnostic view, the volume rendered image appears to rotate. The rotation from one view to another shows the spatial relationship between the views. The user may then examine the static volume rendering at the desired view with an appreciation of the relationship with the previously examined static view.

    摘要: Clipping is provided for volume rendering in three-dimensional medical imaging. Rather than a single or even two clipping planes, an enclosed clipping volume isolates a region of interest. More than one volume rendering may be formed from the data of the clipping volume. The volume renderings from different directions, such as opposite directions, may be displayed substantially simultaneously. For imaging a valve or other structure with multiple views of interest, the clipping volume defines the valve or structure region and rendering from the multiple views provides desired diagnosis information.

    摘要: A system for controlling the point spread function of an ultrasound signal transmitted into a patient. In accordance with one embodiment of the invention, only a selected number of the transducer elements transmit a transmit pulse. The elements which do not transmit the pulse are selected in accordance with an apodization probability density function. In accordance with another aspect of the present invention, each transducer element transmits a variable portion of a transmit pulse in order to control the acoustic power of the signal transmitted from each element.

    摘要: Spatial relationships are conveyed in multi-planar reconstruction (MPR). A 3D MPR display indicates relative position of MPR imaging planes to each other and/or anatomy at a given time. To better assist user understanding of the location of the MPR planes relative to each other and/or anatomy in transitioning to different relative locations, the transition is animated. The shift in planar position occurs gradually in the 3D MPR display despite user indication of a jump to another arrangement.
