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 update algorithms" (Expand Search), "patient atlas algorithms" (Expand Search), "patient each algorithms" (Expand Search), "patient care algorithms" (Expand Search)
"relevant data algorithm" » "relevant update algorithm" (Expand Search), "relevant atlas algorithm" (Expand Search), "relevant each algorithm" (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 ("relevant data algorithm"))) OR ("image processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"patient data algorithms\") OR (\"relevant data algorithm\"))) OR (\"image processing algorithm\"))".
• Removing quotes may allow a broader search: (((( patient data algorithms ) OR ( relevant data algorithm ))) OR ( image processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("patient data algorithms") OR ("relevant data algorithm"))) OR ("image processing algorithm"))*.
