    摘要： The systems and methods described herein provide for fast and accurate image segmentation through the application of a multi-stage classifier to an image data set. An image processing system is provided having a processor configured to apply a multi-stage classifier to the image data set to identify a distinctive region. The multi-stage classifier can include two or more component classifiers. The first component classifier can have a sensitivity level configured to identify one or more target regions in the image data set and the second component classifier can have a specificity level configured to confirm the presence of the distinctive region in any identified target regions. Also provided is a classification array having multiple multi-stage classifiers for identification and confirmation of more than one distinctive region or for the application of different classification configurations to the image data set to identify a specific distinctive region.

    摘要： A prosthesis anchor is adapted to convert a previously untreatable anatomy into a more typical and treatable condition. Preferably, the anchor is adapted to be transported endoluminally to a deployment site in a body lumen. The anchor includes a landing section for securing the anchor at a relatively fixed position in the lumen, and a docking section adapted to receive a mating prosthesis the landing section of the anchor may be permanently affixed to the lumen by a variety of mechanical and/or adhesive fixation means.

    摘要： The systems and methods described herein allow for the application of a bias voltage to one or more transducers implemented within a medical ultrasound imaging system. Bias circuitry is placed within an imaging device and used to apply a DC bias to one or more transducers requiring a DC bias to operate. The one or more transducers can be fabricated in a semiconductor manufacturing process and integrated with the bias circuitry on a common semiconductor substrate. Also provided is a method for operating the one or more transducers and bias circuitry using a communication channel having two signal lines.
