20110144494 | METHODS FOR ACQUISITION AND DISPLAY IN ULTRASOUND IMAGING - In general, the invention provides methods for use in the acquisition and display of ultrasound images. In particular, the invention provides methods for displaying ultrasound images using a persistence algorithm, gating ultrasound acquisition based on subject respiration, triggering ultrasound acquisition based on subject ECG, and destroying bubble contrast agents during imaging. The methods may be employed with any suitable ultrasound system. | 06-16-2011 |
20130083981 | OVERLAY IMAGE CONTRAST ENHANCEMENT - A method of creating an image difference overlay comprises identifying a loop of reference images of a subject and identifying a loop of data images of the subject. The loop of image data can be identified after an event, such as the administration of contrast agent to the subject. A reference loop image frame is compared to one or more data loop image frames and the reference loop frame is associated with a data loop image frame which closely resembles the data loop image frame. Each of the associated frames can then be processed and used to create an image difference overlay frame. | 04-04-2013 |

20140073929 | NOSEPIECE CONFIGURED FOR USE WITH ULTRASOUND PROBES - A system for producing an ultrasound image comprises a scan head having a transducer capable of generating ultrasound energy at a frequency of at least 20 megahertz (MHz), and a processor for receiving ultrasound energy and for generating an ultrasound image at a frame rate of at least 15 frames per second (fps). | 03-13-2014 |
20140128738 | SYSTEM AND METHODS FOR FORMING ULTRASOUND IMAGES - Systems and methods for producing three-dimensional ultrasound images are disclosed herein. In one embodiment, ultrasound image data are acquired in discrete time increments at one or more positions relative to a subject. The image data is time stamped relative to an offset to a reference point. The image data is synchronized relative to the reference point and combined to form a loop of three dimensional images. | 05-08-2014 |
20140336512 | HIGH FREQUENCY, HIGH FRAME-RATE ULTRASOUND IMAGING SYSTEM - A system for producing an ultrasound image comprises a scan head having a transducer capable of generating ultrasound energy at a frequency of at least 20 megahertz (MHz), and a processor for receiving ultrasound energy and for generating an ultrasound image at a frame rate of at least 15 frames per second (fps). | 11-13-2014 |
20140346329 | PHOTOACOUSTIC TRANSDUCER WITH OPTICAL FEEDBACK - A photoacoustic ultrasound transducer receives excitation light on a bundle of optical fibers. The optical fibers in the bundle are divided to direct the excitation light onto light bars positioned on either side of an imaging stack. A small portion of the optical fibers direct a portion of the excitation light onto an optical sensor that is located within the transducer housing. | 11-27-2014 |
