I have a series of images produced by an ultrasound machine. The images are of an eraser. the position of the eraser is in a different as the ultrasound probe moves. I did image registration to register all of the images in respect to frame 1 (I have a total of 180 images). the intensities of the pixels of the eraser are not consistent between the frames. I took the average of the 180 images and the output image was blurred. I was wondering if u can suggest away to me so that I can get a clearer image out of the 180 images other than averaging them. Thank you in advance

See section 20.12 here for algorithms: http://iris.usc.edu/Vision-Notes/bibliography/contentsmedical.html#Medical%20Applications,%20CAT,%20MRI,%20Ultrasound,%20Heart%20Models,%20Brain%20Models. Pick on, code it up, and come back here if you have questions.

Does the scene move between frames? If not, I don't see why averaging frames would produce blur. If they do move, reduce noise on each frame, then call imregister() to align them all, then do averaging.
