What is Yottalook?
Yottalook™ is a free medical imaging search engine that provides decision support at the point of care using proprietary relevance and ranking algorithms by iVirtuoso. Yottalook™ is designed to provide the practicing radiologists the most important and most relevant information they need at the time of patient care.
Core Technologies
Yottalook™ is based on core technologies developed by iVirtuoso to achieve optimized search results. First is automated analysis of the search term to understand what the radiolgist is trying to look for - this core technology is called "natural query analysis".
Yottalook™ has also developed a thesaurus of medical terminologies that not only identifies synonyms of terms but also defines relationships between terms. This second core technology is called "semantic ontology" and is based on existing medical ontologies that have been enhanced by iVirtuoso, such as RadLex - A Lexicon for Uniform Indexing and Retrieval of Radiology Information Resources developed by the Radiology Society of North America.
Third core technology is "relevance algorithm" for image search that differentiates medical terms from other words in text associated with medical images and uses them to create ranking for Yottalook image search.
The fourth core technology is a specialized content delivery system called "Yottalinks" that provides high yield content based on the search term. This content may also be provided by a third party vendor licensing Yottalook search. Yottalook™ can be integrated with any web based medical application so that context relevant information is provided to the physician at the point of care. If you are interested in integrating Yottalook™ with your application or website, you can contact us to discuss possible opportunities.
Search Engines
Currently, Yottalook Web, Yottalook Images, Yottalook Anatomy and Yottalook Book search engines are available for use. Yottalook Web has been designed to search online radiology sources only. Try various refinement options to narrow your search requests even further. Yottalook Images has specially been designed to search radiology images from various peer-reviewed online sources and currently has access to over 700,000 images. Yottalook Anatomy focuses results to provide higher ranking to anatomic or radiographic atlases. Yottalook Books search filters Google Books search results to provide links to radiology or imaging related books. With Yottalook Books, you can read relevant content from full-text radiology books online.
Yottalook Development
Yottalook™ was developed and actively maintained by four radiologists: Woojin Kim MD, Khan M. Siddiqui MD, William Boonn MD and Nabile Safdar MD. Yottalook™ is a continued work-in-progress and is undergoing numerous developments. Please feel free to contact us with comments and suggestions.
