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