A method for imaging a patient using an intravascular ultrasound imaging system includes inserting a catheter into a target imaging region within patient vasculature. The catheter includes at least one transducer coupled to a control module. A plurality of image frames is generated as the at least one transducer is moved within patient vasculature. The image frames are based on data obtained from a plurality of echo signals reflected from patient tissue in response to a plurality of acoustic signals output from the at least one transducer. Each image frame includes a motion-blur component. A motion-blur-intensity estimate is quantified for each image frame to form a motion-blur-estimation signal that varies over time and that includes periodic local motion blur minima. Temporal variations of the motion-blur components are filtered to reduce variation in the motion-blur-intensity estimate arising from vessel structure variation. Image frames are selected that contain local motion blur minima.
