TARGETED ADDITIVE GAIN TOOL FOR PROCESSING ULTRASOUND IMAGES

摘要

Ultrasound image processing system including a processor ( 16 ) for receiving a sequence of ultrasound image frames each including an object with a border and causing the ultrasound image frames to be displayed, and a user input device ( 20 ) for designating variable local regions of the displayed ultrasound image frames. A border detection algorithm ( 22 ) detects the border of the object in the ultrasound image frames and a target additive gain (TAG) tool ( 24 ) selectively adjusts pixel intensity in at least one local region of the ultrasound image frames with an unclear or non-existent border segment in order to make the pixel intensity more uniform. A more uniform pixel intensity improves the discerning of the border of the object via the border detection algorithm ( 22 ). Once the border of the object is sufficiently discernible, the object can be reviewed or quantified. If the object is the heart, the LV volume can be determined.
