A Motion-Compensated Filter for Ultrasound Image Sequences

Lee Markosien

May 1996


Medical ultrasound images are an important diagnostic tool for physicians, but suffer from low image intensity, dropouts, and noise in the form of speckle. I propose a new method for filtering ultrasound image sequences which is based on a motion-compensated temporal filter. The key contribution is a new method for detecting and tracking image features which is fully automatic. Applying this algorithm in a motion-compensated temporal filter demonstrates its worth. The tracking and filtering algorithms together run at speeds approaching real-time on a standard scientific workstation.
