  • Automated heart rate detection for 3D ultrasonic fetal imaging
    Patent number: 9044196
    Abstract: An ultrasound system and method provide a workflow to acquire 3D images of the fetal heart gated by a synthetic heart gating signal. An ROI is defined in an ultrasound image which delineates the fetal heart. The ultrasound system is controlled to automatically estimate the fetal heart rate from echo signals received from the ROI. When the system has acquired a stable synthetic heart rate signal, an indication thereof is given to the user and the user then commands the system to acquire 3D fetal heart images for a number of fetal heart cycles which are gated using the synthetic heart rate signal.

  • Reagent Magazine with Motor Latch Coupler
    Publication number: 20150135502
    Abstract: A motorized latch assembly includes an electric motor, an eccentric cam attached via gears to a shaft of the motor and a latch plate configured to lock the reagent cartridge to the coupler. The eccentric cam is rotated when the shaft of the motor rotates. When the eccentric cam is rotated so that the eccentric cam presses down upon the latch plate, the latch plate moves a sufficient distance to permit the reagent cartridge to be disconnected from the coupler.
