Abstract
Colonoscopy simulation has been increasingly applied as a method of training, which can supplement the traditional patient-based training in recent years. However, the current level of realism of the simulation is insufficient. One of the main difficulties degrading the realism is real-time simulation of colon deformation involving multi-contact interaction with the endoscope.

Cylindrical lattices and a centre-line are employed as the skeletons, and a mass-spring model is applied to the skeletons for the mechanics-based simulation. The centre-line-based collision detection and resolution algorithm is proposed to simulate the interaction between the colon and endoscope. A haptic rendering algorithm using the energy method is proposed to produce feedback force, based on physical interaction between the colon and endoscope.</AbstractText><AbstractText Label="RESULTS" NlmCategory="RESULTS">The proposed simulation framework has been implemented and evaluated in colonoscopy simulation. The simulation results show that the proposed method allows real-time simulation (28 Hz) using a colon model composed of up to 241,440 meshes.</AbstractText><AbstractText Label="CONCLUSIONS" NlmCategory="CONCLUSIONS">The proposed method allows real-time simulation of colon and endoscope deformation while maintaining a visually plausible result and realistic haptic sensation.</AbstractText><CopyrightInformation>Copyright © 2012 John Wiley & Sons, Ltd.</CopyrightInformation></Abstract><AuthorList CompleteYN="Y"><Author ValidYN="Y"><LastName>Jung</LastName><ForeName>Hoeryong</ForeName><Initials>H</Initials><AffiliationInfo><Affiliation>Department of Mechanical Engineering, KAIST, Daejeon, Republic of Korea.</Affiliation></AffiliationInfo></Author><Author ValidYN="Y"><LastName>Lee</LastName><ForeName>Doo Yong</ForeName><Initials>DY</Initials></Author><Author ValidYN="Y"><LastName>Ahn</LastName><ForeName>Woojin</ForeName><Initials>W</Initials></Author></AuthorList><Language>eng</Language><PublicationTypeList><PublicationType UI="D023362">Evaluation Studies</PublicationType><PublicationType UI="D016428">Journal Article</PublicationType><PublicationType UI="D013485">Research Support, Non-U.S. Gov't</PublicationType></PublicationTypeList><ArticleDate DateType="Electronic"><Year>2012</Year><Month>02</Month><Day>01</Day></ArticleDate></Article><MedlineJournalInfo><Country>England</Country><MedlineTA>Int J Med Robot</MedlineTA><NlmUniqueID>101250764</NlmUniqueID><ISSNLinking>1478-5951</ISSNLinking></MedlineJournalInfo><CitationSubset>IM</CitationSubset><MeshHeadingList><MeshHeading><DescriptorName MajorTopicYN="N" UI="D000465">Algorithms</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D001696">Biomechanical Phenomena</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D003106">Colon</DescriptorName><QualifierName MajorTopicYN="N" UI="Q000033">anatomy & histology</QualifierName><QualifierName MajorTopicYN="N" UI="Q000502">physiology</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D003113">Colonoscopy</DescriptorName><QualifierName MajorTopicYN="Y" UI="Q000193">education</QualifierName><QualifierName MajorTopicYN="N" UI="Q000295">instrumentation</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D003196">Computer Graphics</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="Y" UI="D003198">Computer Simulation</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="Y" UI="D003194">Computer-Assisted Instruction</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D006801">Humans</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D013314">Stress, Mechanical</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D014584">User-Computer Interface</DescriptorName></MeshHeading></MeshHeadingList></MedlineCitation><PubmedData><History><PubMedPubDate PubStatus="accepted"><Year>2011</Year><Month>12</Month><Day>7</Day></PubMedPubDate><PubMedPubDate PubStatus="aheadofprint"><Year>2012</Year><Month>2</Month><Day>1</Day></PubMedPubDate><PubMedPubDate PubStatus="entrez"><Year>2012</Year><Month>2</Month><Day>3</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="pubmed"><Year>2012</Year><Month>2</Month><Day>3</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="medline"><Year>2013</Year><Month>1</Month><Day>18</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate></History><PublicationStatus>ppublish</PublicationStatus><ArticleIdList><ArticleId IdType="doi">10.1002/rcs.1414</ArticleId><ArticleId IdType="pubmed">22298385</ArticleId></ArticleIdList></PubmedData></pubmed></record>Pour manipuler ce document sous Unix (Dilib)
