Abstract
The present invention is a novel method for producing real-time colorized, contrast enhanced images from a sequence of grey-scale video images obtained during diagnostic ultrasound. The particular colorizing scheme varies according to which information parameter is desired to be displayed in real-time. The information parameters used to colorize a segment of video images include: time-to-arrival, duration of brightening, and absolute brightening. Time-to-arrival colorization depicts the time that a given pixel achieves a given intensity threshold. Duration of brightening depicts the time that a given pixel's intensity stays above a given threshold. Absolute brightening depicts various threshold values obtained by the region's pixels.
