Patent number: 10456116Abstract: Shadow suppression is provided in ultrasound imaging, such as in steered spatial compounding. Using a transform or other approach, the data of a frame of data along the steering direction is projected. The projection is used to determine weights. The frame is weighted with the projection-based weights, reducing or removing shadows based on the one frame rather than based on registration with other frames. In the steered spatial compounding example, a compounded frame with independently shadow suppressed component frames may have little or no fork-like image artifacts due to shadowing.Type: GrantFiled: September 30, 2014Date of Patent: October 29, 2019Assignee: Siemens Medical Solutions USA, Inc.Inventors: David P.

Patent number: 10448901Abstract: An embodiment in accordance with the present invention provides a method and system for evaluating regional cardiac function and dyssynchrony from an imaging modality using the motion of endocardial features of the heart. In the method and system, an imaging modality such as a CT scanner is used to obtain an image sequence that is then processed using a computer program. The computer program is configured to create an endocardial mesh formed from triangular components that represents at least the region of interest of the subject's heart. From tracking the motion of conserved topological features on this endocardial mesh at least two time points a displacement map can be modeled. The displacement map can be further analyzed to determine metrics of regional cardiac function such as SQUEEZ, myocardial strain, torsion etc., and the displacement map can also be used to create visual representations of the function of the subject's heart.Type: GrantFiled: October 12, 2012Date of Patent: October 22, 2019Assignee: The Johns Hopkins UniversityInventors: Elliot Ross McVeigh, Amir Pourmorteza

Patent number: 10448924Abstract: An ultrasonic diagnostic imaging system for shear wave measurement transmits push pulses in the form of a sheet of energy. The sheet of energy produces a shear wavefront which is a plane wave, which does not suffer from the 1/R radial dissipation of push pulse force as does a conventional push pulse generated along a single push pulse vector. The sheet of energy can be planar, curved, or in some other two or three dimensional shape. A curved sheet of energy can produce a shear wave source which focuses into a thin line, which increases the resolution and sensitivity of the measuring techniques used to detect the shear wave effect.Type: GrantFiled: December 2, 2011Date of Patent: October 22, 2019Assignee: KONINKLIJKE PHILIPS N.V.Inventors: John Douglas Fraser, Roy Peterson, Jean-Luc Robert, Vijay Shamdasani, Hua Xie
