Perhaps you should try some spelling variations:
base optimization » based optimization (Expand Search), phase optimization (Expand Search), dose optimization (Expand Search)
data optimization » path optimization (Expand Search), dose optimization (Expand Search), art optimization (Expand Search)
marker base » market based (Expand Search), market case (Expand Search), marker band (Expand Search)
binary mask » binary image (Expand Search)
mask data » risk data (Expand Search), tsk data (Expand Search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( binary marker base optimization algorithm ) OR ( binary mask data optimization algorithm )).
