Latest Patents

One of her latest patents is titled "Method for maintaining a constant velocity to color map in an ultrasound." This invention employs pulsed Doppler ultrasound signals to color image blood and tissue movement velocities in a body. The method initially images a movement with a transmitted ultrasound signal that manifests a current signal transmission frequency value and a current pulse repetition frequency (PRF) value. These values exhibit a determined ratio R to each other. In response to a user indication that movement is to be imaged at a new depth, the method alters the current transmission frequency to a new frequency to provide improved signal back-scatter from movement at the new depth. The current PRF is then automatically adjusted to a new PRF value, ensuring that the mapping of movement velocity values to colors is maintained, despite the use of a new transmission frequency.

Another significant patent is the "Quick method and apparatus for identifying a region of interest in an ultrasound." This ultrasound display system enables a user to rapidly identify a region of interest (ROI) in a displayed ultrasound image without having to trace the outline of the ROI. The system includes a display and a processor that manifests an ultrasound image. A user entry device allows the user to initiate a 'quick ROI' identification procedure, causing the processor to superimpose a closed geometric figure on the displayed ultrasound image. The user can adjust this figure to enclose the ROI, and upon user selection, the processor identifies the boundary of the ROI and carries out calculations regarding the determined ROI boundary.
