20080242996 | Method and apparatus for measuring flow in multi-dimensional ultrasound - A method and system are provided for estimating velocity of flow within an ultrasound dataset. A sample volume gate is defined on a two-dimensional (2D) image. The 2D image is based on an ultrasonic dataset. Spectral Doppler velocity estimates of flow are detected within the sample volume gate in first and second dimensions that are orthogonal with respect to each other. A true velocity estimate of the flow within the sample volume gate is determined based on the Doppler velocity estimates. | 10-02-2008 |
20080287799 | Method and apparatus for measuring volumetric flow - An ultrasound system comprises an ultrasound probe, a user interface and a processor. The ultrasound probe comprises a transducer face emitting ultrasound beams into a patient. The probe acquires a volume of ultrasound data comprising a blood vessel. The user interface defines a surface on an image that is based on the volume. The surface bisects the blood vessel and further comprises a plurality of points where at least some of the points are located at unequal distances with respect to the transducer face. The processor is configured to steer a subset of the ultrasound beams to intersect the surface at a 90 degree angle and calculate volumetric flow information through the blood vessel based on the ultrasound data corresponding to the surface. | 11-20-2008 |
20100063400 | METHOD AND APPARATUS FOR CATHETER GUIDANCE USING A COMBINATION OF ULTRASOUND AND X-RAY IMAGING - An apparatus for tracking movement of a foreign object within a subject has an X-ray fluoroscopic system with an X-ray detector and an ultrasound system that has a probe with a position sensor. A display is configured to display a static X-ray image acquired by the X-ray fluoroscopic system and a real-time ultrasound image acquired by the ultrasound system. The X-ray image and the ultrasound image each display at least a portion of the foreign object and at least a portion of surrounding area. A tracking module is configured to track movement of the foreign object within the ultrasound image and the display is further configured to display an indication of the movement of the foreign object on the X-ray image | 03-11-2010 |
20100152578 | MEDICAL IMAGING SYSTEM AND METHOD CONTAINING ULTRASOUND DOCKING PORT - An ultrasound medical imaging system and non-ultrasound medical imaging system are combined and communicate via a suitable docking port, which is supported by the non-ultrasound medical imaging system and configured to receive the ultrasound medical imaging system. The systems can communicate directly, indirectly, and/or wirelessly. Each can also be configured for cross-imaging in the other modality, displaying medical imagery from the other modality on respective and/or combined displays, and/or control by a user interface of the other and/or a common user interface. Registry between patient imagery is possible, and improved workflow is provided. | 06-17-2010 |

20100246760 | COMBINING X-RAY AND ULTRASOUND IMAGING FOR ENHANCED MAMMOGRAPHY - A mammography system includes a patient support with a breast opening. Beneath the patient support, an x-ray source transmits x-rays through a breast of a patient extending through the opening. An opposing x-ray detector receives the x-rays to obtain an x-ray image of the breast. The x-ray source and x-ray detector rotate around the opening while maintaining a fixed relation relative to one another, and a container is filled with a fluid and positioned proximate to and aligned with the opening to receive the breast. An ultrasound transmitter transmits sound waves through the breast when positioned within the fluid. An opposing ultrasound receiver receives the sound waves to obtain an ultrasound image of the breast. In a preferred embodiment, the mammography system positions the ultrasound transmitter and/or ultrasound receiver at a first position when obtaining the x-ray image of the breast and a second position when obtaining the ultrasound image of the breast. In other preferred embodiments, mammography methods correspond thereto. | 09-30-2010 |
20110216957 | APPARATUS AND METHOD FOR RECONSTRUCTING AN IMAGE WITH REDUCED MOTION ARTIFACTS - A computer readable storage medium having a computer program stored thereon and representing a set of instructions that when executed by a computer causes the computer to calculate a mapping function that provides a location of each sub-volume of an imaging volume as a function of time from ultrasound data and determine a respective acquisition window for each sub-volume of the imaging volume from the mapping function. The instructions also cause the computer to reconstruct an image of the imaging volume substantially free of motion artifacts from imaging data acquired from the imaging volume. | 09-08-2011 |
20110218423 | WEARABLE ULTRASOUND PROBE ASSEMBLY AND METHOD OF MANUFACTURING SAME - A wearable ultrasound probe apparatus includes a wearable membrane. An ultrasound transducer is also included that is integrated into the wearable membrane and configured to maintain a substantially consistent contact with a surface of an object to be imaged when the object has the wearable membrane disposed thereon. | 09-08-2011 |
20110218438 | ULTRASOUND APPARATUS AND METHOD OF MANUFACTURING SAME - An ultrasound apparatus includes an ultrasound probe and a probe positioning device operably connected to the ultrasound probe. The probe positioning device is configured to provide one of an orientation and a position of the ultrasound probe during ultrasound imaging. | 09-08-2011 |
