20110054317 | TRACKING AND OPTIMIZING GAIN AND CONTRAST IN REAL-TIME FOR ULTRASOUND IMAGING - A system for dynamic optimization of gain and contrast in ultrasound imaging includes an image processor module programmed to dynamically estimate a correction profile in real-time and apply the correction profile to adjust a gain and contrast of image frame data sets. The image processor module is programmed to identify tissue and background regions in an image frame data set, determine an image intensity for each of the tissue and background regions, and formulate a gain profile based on the image intensity of the tissue region to compensate the gain variation of an image. The image processor module is further programmed to calculate an image contrast metric based on the image intensity of the tissue and background regions, and modify a gray map of the image frame data set based on the image contrast metric to adjust the contrast of an image displayed on the display system. | 03-03-2011 |

20100063398 | ULTRASOUND PROBE FOR GUIDANCE PROCEDURES - An ultrasound probe for guidance procedures is provided. The ultrasound probe includes a linear transducer array and a micro-motor configured to mechanically move the linear transducer array to provide ultrasound guidance of procedures. | 03-11-2010 |
20110160591 | FETAL HEART RATE MONITOR WITH WIDE SEARCH AREA - A continuous, non-invasive fetal heart rate measurement is produced using an ultrasound probe positioned on the abdomen of the mother. The ultrasound probe includes a plurality of ultrasound transducers that are positioned within a housing having a transmission surface. The transmission surface is configured to defocus the individual ultrasound beams created by the plurality of ultrasound transducers. The transmission surface defocuses the ultrasound beam and creates a wider area of coverage for the ultrasound probe. The controller contained within the heart rate monitor selectively activates different combinations of the plurality of ultrasound transducers to reduce the signal-to-noise ratio while allowing the ultrasound probe to locate the fetal heart beat and subsequently increase the signal-to-noise ratio during continuous heart rate monitoring. | 06-30-2011 |
