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.
