  • Patent number: 6773401
    Abstract: The use of any micro-mechanical component in an ultrasound system is disclosed. In particular, the use of micro-relays, micro-switches and inductors in the transducer probe head, in the transducer connector, coupled with the system transducer connector(s) or anywhere else in the system. In an ultrasound system, micro-mechanical components such as micro-fabricated switches, relays and inductors permit impressive size reduction, cost reduction, signal-integrity enhancement and improved operational flexibility.

  • Patent number: 6659955
    Abstract: The preferred embodiments described herein provide medical diagnostic ultrasound imaging system transmitter control in a modular transducer system. With these preferred embodiments, transmitters in a medical diagnostic ultrasound imaging system are enabled only when contacts in a scan head are electrically coupled with contacts in a receptacle assembly of a modular transducer system. This prevents high voltages from developing in the receptacle assembly when the scan head is removed from or is not fully engaged with the receptacle assembly. In one preferred embodiment, a detector is used to detect movement of a member comprising the contacts in the receptacle assembly. Other preferred embodiments are provided, and each of the preferred embodiments described herein can be used alone or in combination with one another.

  • Patent number: 6612992
    Abstract: A catheter and method for determining a position of the catheter within the cardiovascular system is provided. Local bending and twisting is measured at multiple locations along the catheter. By integrating the measurements, the position and orientation of the catheter is determined. Based on the catheter position information, the location and orientation of an ultrasound transducer array connected with the catheter is known. The imaging array position and orientation information may be used to assist a physician in determining the tissue structure or fluid being scanned and/or assist in the accurate generation of three-dimensional representations.

  • Patent number: 6535615
    Abstract: A method and system are provided for facilitating interaction between image and non-image sections displayed on an image review station. With the preferred embodiments, a user can interact with image and non-image sections without changing focus between the sections, thereby allowing the user to be much more efficient in the use of the medical image review station. In one presently preferred embodiment, an image review station processor determines which operation should be performed based on a position of a displayed pointer, regardless of which section is under focus. In another presently preferred embodiment, a user interface device is dedicated to either an image or non-image section such that input from the dedicated user interface device will be applied to the corresponding section regardless of which section is in focus.

  • Patent number: 6524245
    Abstract: The preferred embodiments described herein provide a medical diagnostic ultrasound imaging system and method for network management. In one preferred embodiment, a medical diagnostic ultrasound imaging system network is presented comprising first and second medical diagnostic ultrasound imaging systems coupled with a processor. An error message is sent from the first medical diagnostic ultrasound imaging system to the processor, and the processor automatically analyzes and responds to the error message. In another preferred embodiment, configuration information from the first and second medical diagnostic ultrasound imaging systems is sent to the processor. Based on the configuration information sent from the first medical diagnostic ultrasound imaging system, the processor automatically selects a software application from a plurality of software applications and sends the selected software application to the first medical diagnostic ultrasound imaging system.

  • Patent number: 6503202
    Abstract: Medical diagnostic ultrasound methods and systems for automated flow analysis are provided. Multiple cross-sectional areas along a vessel are determined automatically. A processor locates an abnormality as a function of the multiple cross-sectional areas, such as identifying a cross-sectional area that is a threshold amount less than an average cross-sectional area. The abnormal area is highlighted on the display to assist with medical diagnosis. For the carotid artery, the interior and exterior branches are labeled to assist medical diagnosis. The two branches are automatically identified. The branch associated with additional small branches is identified as the exterior carotid.
