| 20110276314 | Method for Calculating The Sphericity of a Structure - Sphericity of a structure can be determined using the technology described herein. A system for determining sphericity can include a computer processor configured to compute a covariance matrix for a three dimensional model of a structure. The processor can be configured to calculate a sphericity of the structure using the covariance matrix and a long-axis vector associated with a long axis of the modeled structure. In certain embodiments, the processor can be configured to compute the sphericity as a ratio between a determinant of the covariance matrix and a cubed extent of the model in the long-axis direction. Certain embodiments can include an imaging device, such as an ultrasound scanner, for example, configured to capture an image of the structure and obtain a model of the structure. Certain embodiments can include a user interface configured to allow a user to identify the long axis of the modeled structure. | 11-10-2011 |
| 20120065510 | ULTRASOUND SYSTEM AND METHOD FOR CALCULATING QUALITY-OF-FIT - An ultrasound imaging system and method include generating an image from ultrasound data of an anatomical structure and fitting a model to the image, the model including a standard view of the anatomical structure. The system and method include calculating a quality-of-fit of the image to the model. The system and method include displaying an indicator based on the quality-of-fit of the image to the model. | 03-15-2012 |
| 20120155727 | METHOD AND APPARATUS FOR PROVIDING MOTION-COMPENSATED IMAGES - A method for performing motion compensated temporal filtering of a three-dimensional (3D) image dataset includes accessing with a processor a three-dimensional (3D) dataset comprising a plurality of images, the images including at least a first 3D image acquired at a first time and a different second 3D mage acquired at a second time, determining a phase correlation between at least one patch in the first 3D image and at least one patch in the second 3D image, generating 3D displacement vectors that represents displacement between a patch in the first 3D image and the patch in the second 3D image, and generating at least one 3D image using one or more 3D displacement vectors. A non-transitory computer readable medium and an ultrasound imaging system are also described herein. | 06-21-2012 |
| 20120157845 | METHOD AND APPARATUS FOR MOTION-COMPENSATED ULTRASOUND IMAGING - An ultrasound imaging system and method include acquiring first ultrasound data, the first ultrasound data comprising data of a first plane through a structure of interest. The ultrasound imaging system and method include tracking the motion of a landmark based on the first ultrasound data. The ultrasound imaging system and method acquiring second ultrasound data, the second ultrasound data including data of a second plane through the structure of interest, the second plane being distinct from the first plane, where the position of the second plane is adjusted to track the motion of the landmark. The ultrasound imaging system and method also includes generating an image based on the second ultrasound data. | 06-21-2012 |
| 20120245465 | METHOD AND SYSTEM FOR DISPLAYING INTERSECTION INFORMATION ON A VOLUMETRIC ULTRASOUND IMAGE - A method and system for displaying intersection information on a volumetric ultrasound image are provided. One method includes accessing ultrasound information corresponding to a volume dataset and identifying a location of one or more surfaces intersecting the volume dataset. The method further includes colorizing a rendered image of the volume dataset based on the identified locations of the intersection of the one or more surfaces and displaying a rendered volume dataset with one or more colorized intersections. | 09-27-2012 |
