METHOD OF COMPOUNDING AN ULTRASOUND IMAGE

摘要

In a method of compounding an ultrasound image, ultrasound signals having a transmission frequency are transmitted to a target object at a predetermined steer angle. Then, signals reflected by the target object are received. Based on the received signals, an image frame is formed. By repeating the above steps with different transmission frequencies, two or more image frames are obtained. The obtained image frames are then combined to provide a compound ultrasound image. The steer angle varies based on the transmission frequency.
