FEATURE TRACING PROCESS FOR M- MODE IMAGES

摘要

A process for tracing an operator selected feature in an M-mode ultrasonic image comprises selecting a pixel of the selected feature within the M-mode image. A reference region is generated about the selected feature pixel and image intensity values are extracted for the reference region. A time point is selected in the M-mode ultrasonic image wherein the time point is at a different time than the selected feature pixel and a comparison region is generated about the selected time point. Image intensity values are extracted for the comparison region and a difference error is calculated for each location within- the comparison region by comparing the reference region image intensity values with the comparison regions image intensity values. The location that has the smallest difference error is identified as a feature pixel at the time point.
