  • Method and apparatus for improved spatial and temporal resolution in ultrasound imaging
    Patent number: 6537217
    Abstract: A method is provided to simultaneously acquire two ultrasound images. A first set of ultrasound pulses are transmitted at a first frame rate utilizing a first mode of operation. The echoes from the first set of ultrasound pulses are received. A second set of ultrasound pulses are transmitted at a second frame rate utilizing a second mode of operation. The first and second frame rates are different. The first set of ultrasound pulses defines an entire image, while the second set of ultrasound pulses defines a partial image. The echoes from the second set of ultrasound pulses are received, and the echoes from the first and second sets of ultrasound pulses are displayed as a single image.

  • Ultrasound image acquisition with synchronized reference image
    Patent number: 6488629
    Abstract: A system and a method for guiding and helping an ultrasound scanner user to acquire the correct projection/cut-plane when acquiring images of a physiological structure for comparison with previously acquired images. The ultrasound scanner screen area is divided in two parts, where one part is showing a reference image loop and the other part is showing the live image loop. The correct reference image loop is automatically retrieved from the image frame memory based on which cell in the stress protocol is active. The reference image loop is cycled with a speed which is automatically set by the software based on the current heart rate given by the live ECG acquisition. The display of the reference loop is “reset” (starting from the first image in the loop) at QRS trigger detection from the live ECG signal.
