Perhaps you should try some spelling variations:
"image processing algorithm" » "image modeling algorithm" (Expand Search), "image routing algorithm" (Expand Search), "image tracking algorithm" (Expand Search)
"patient data algorithms" » "patient art algorithms" (Expand Search), "patient all algorithms" (Expand Search), "patient both algorithms" (Expand Search), "patient care algorithms" (Expand Search)
"element tree algorithms" » "element three algorithms" (Expand Search), "element art algorithms" (Expand Search), "element two algorithms" (Expand Search), "element ree algorithms" (Expand Search), "element te algorithms" (Expand Search), "element ore algorithms" (Expand Search)

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("patient data algorithms") OR ("element tree algorithms"))) OR ("image processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"patient data algorithms\") OR (\"element tree algorithms\"))) OR (\"image processing algorithm\"))".
• Removing quotes may allow a broader search: (((( patient data algorithms ) OR ( element tree algorithms ))) OR ( image processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("patient data algorithms") OR ("element tree algorithms"))) OR ("image processing algorithm"))*.
