Patent number: 9824442Abstract: For volume ultrasound imaging, the view direction for rendering a volume image is used. In one approach, imaging parameters for acquiring the volume data prior to rendering are set based on the view direction. For the resolution example, the data for imaging is acquired with the resolution in a view plane greater than resolution along the ray tracing direction. In another approach, sets of data representing a volume are acquired or formed with different settings. The sets are weighted based on the view direction and combined. For the resolution example, an image rendered from the combined data may have greater resolution in the view plane where the set of data with greater resolution in that view plane is weighted more in the combination.Type: GrantFiled: August 20, 2015Date of Patent: November 21, 2017Assignee: Siemens Medical Solutions USA, Inc.Inventors: Liang Zhai, Henry Pavy, Bimba Rao, Bruce A.

Patent number: 9460538Abstract: 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.Type: GrantFiled: August 7, 2013Date of Patent: October 4, 2016Assignee: Siemens Medical Solutions USA, Inc.Inventors: Mervin Mencias Smith-Casem, Bruce A.

Patent number: 9196092Abstract: 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.Type: GrantFiled: June 11, 2012Date of Patent: November 24, 2015Assignee: Siemens Medical Solutions USA, Inc.Inventors: Bruce A.

Patent number: 8922554Abstract: An irregular ultrasound sampling grid is reconstructed to a three-dimensional grid for imaging. Volume data acquired with a helix transducer includes a fractional offset of data spaced along one dimension, resulting in the irregular ultrasound sampling grid. To determine a voxel value for a grid point on a uniform grid, two adjacent planes are identified. The sample locations in the two planes are not aligned, being on the irregular ultrasound sampling grid. Hardware acceleration devices, such as a graphics processing unit, perform bilinear interpolation in each of the planes. The data of each plane is interpolated to the proper global azimuth-range coordinate corresponding with the grid point. The bilinearly interpolated values from each plane are then linearly interpolated to the grid point.Type: GrantFiled: March 18, 2011Date of Patent: December 30, 2014Assignee: Siemens Medical Solutions USA, Inc.Inventors: Mervin Smith-Casem, Patric Ljung, Guillaume Stordeur, Jian-Hua Mo, Bruce McDermott

Patent number: 8636666Abstract: Rendering quality parameter values are automatically set or adjusted as a function of acquisition ultrasound parameter values. The rendering quality is automatically selected based on the acquisition quality, such as providing for a higher quality or quality rendering for slower acquisitions. More than two rendering states are provided for a respective, more than two different quality settings.Type: GrantFiled: September 16, 2008Date of Patent: January 28, 2014Assignee: Siemens Medical Solutions USA, Inc.Inventors: Nikolaos Pagoulatos, Bruce A.

Publication number: 20130328874Abstract: Volume rendering with a clipping surface is provided in three-dimensional medical imaging. An open curved surface is defined for clipping.

Patent number: 8494250Abstract: 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.Type: GrantFiled: January 9, 2009Date of Patent: July 23, 2013Assignee: Siemens Medical Solutions USA, Inc.Inventors: Bruce A.

Patent number: 8425422Abstract: 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.Type: GrantFiled: April 30, 2009Date of Patent: April 23, 2013Assignee: Siemens Medical Solutions USA, Inc.Inventors: Seshadri Srinivasan, Patric Ljung, Bruce A.

Publication number: 20060020207Abstract: Rendering quality parameter values are automatically set or adjusted as a function of acquisition ultrasound parameter values. The rendering quality is automatically selected based on the acquisition quality, such as providing for a higher quality or quality rendering for slower acquisitions. More than two rendering states are provided for a respective, more than two different quality settings. For example, different quality settings are provided for streaming (non-repetitive on-going rendering), manipulation (edits of a rendered image), frozen and animation states (repetitive or looped rendering). Since the frozen state is less limited by processing time, the frozen state may be rendered with a highest quality or quality. The rendering is provided with two different sampling density variables, such as an in-plane or XY sampling density and a viewing direction or z sampling density. The separation may allow for a more versatile trade-off between image quality and performance.Type: ApplicationFiled: July 12, 2004Publication date: January 26, 2006Inventors: Nikolaos Pagoulatos, Bruce McDermott, Thomas Lindh, Roderick Gauss

Patent number: 6599245Abstract: 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.Type: GrantFiled: June 27, 2000Date of Patent: July 29, 2003Assignee: Siemens Medical Solutions USA, Inc.Inventors: Qinglin Ma, John C.
