Each control point constitutes a particle in a mass spring grid which limits the space of allowed movements to elastic movements. Control points are manipulated by the haptic device, and the negative gradient of the similarity metric over the corresponding block is rendered as a force on the haptic device guiding the user to a minimum of the optimization landscape. Fast update of forces was achieved by exploiting the GPU for computations of the similarity metric and for interpolation of the deformation field.</AbstractText><AbstractText Label="RESULTS" NlmCategory="RESULTS">We show that haptic guided registration facilitates faster and improved registration compared to using a purely visual alignment in a user study on synthetic images. We also demonstrate feasibility of applying the system on medical images through a comparison with an automatic block matching algorithm. A radiologist performing registration with the haptic registration system posted faster registration times and better registration results than the automatic block matching algorithm when using identical grid and block sizes.</AbstractText><AbstractText Label="CONCLUSIONS" NlmCategory="CONCLUSIONS">Possible applications of the system are refinement of registration results from automatic registration methods and construction of initial state used in automatic deformable registration methods.</AbstractText></Abstract><AuthorList CompleteYN="Y"><Author ValidYN="Y"><LastName>Risholm</LastName><ForeName>Petter</ForeName><Initials>P</Initials><AffiliationInfo><Affiliation>Center of Mathematics for Applications, University of Oslo, Oslo, Norway. pettri@ifi.uio.no</Affiliation></AffiliationInfo></Author><Author ValidYN="Y"><LastName>Samset</LastName><ForeName>Eigil</ForeName><Initials>E</Initials></Author></AuthorList><Language>eng</Language><PublicationTypeList><PublicationType UI="D003160">Comparative Study</PublicationType><PublicationType UI="D016428">Journal Article</PublicationType></PublicationTypeList><ArticleDate DateType="Electronic"><Year>2009</Year><Month>02</Month><Day>24</Day></ArticleDate></Article><MedlineJournalInfo><Country>Germany</Country><MedlineTA>Int J Comput Assist Radiol Surg</MedlineTA><NlmUniqueID>101499225</NlmUniqueID><ISSNLinking>1861-6410</ISSNLinking></MedlineJournalInfo><CitationSubset>IM</CitationSubset><MeshHeadingList><MeshHeading><DescriptorName MajorTopicYN="N" UI="D003952">Diagnostic Imaging</DescriptorName><QualifierName MajorTopicYN="Y" UI="Q000379">methods</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D006801">Humans</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D021621">Imaging, Three-Dimensional</DescriptorName><QualifierName MajorTopicYN="Y" UI="Q000379">methods</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="Y" UI="D019047">Phantoms, Imaging</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D015203">Reproducibility of Results</DescriptorName></MeshHeading></MeshHeadingList></MedlineCitation><PubmedData><History><PubMedPubDate PubStatus="received"><Year>2008</Year><Month>8</Month><Day>5</Day></PubMedPubDate><PubMedPubDate PubStatus="accepted"><Year>2009</Year><Month>2</Month><Day>5</Day></PubMedPubDate><PubMedPubDate PubStatus="aheadofprint"><Year>2009</Year><Month>2</Month><Day>24</Day></PubMedPubDate><PubMedPubDate PubStatus="entrez"><Year>2009</Year><Month>12</Month><Day>25</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="pubmed"><Year>2009</Year><Month>12</Month><Day>25</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="medline"><Year>2010</Year><Month>3</Month><Day>20</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate></History><PublicationStatus>ppublish</PublicationStatus><ArticleIdList><ArticleId IdType="doi">10.1007/s11548-009-0291-4</ArticleId><ArticleId IdType="pubmed">20033588</ArticleId></ArticleIdList></PubmedData></pubmed><affiliations><list><country><li>Norvège</li></country></list><tree><noCountry><name sortKey="Samset, Eigil" sort="Samset, Eigil" uniqKey="Samset E" first="Eigil" last="Samset">Eigil Samset</name></noCountry><country name="Norvège"><noRegion><name sortKey="Risholm, Petter" sort="Risholm, Petter" uniqKey="Risholm P" first="Petter" last="Risholm">Petter Risholm</name></noRegion></country></tree></affiliations></record>Pour manipuler ce document sous Unix (Dilib)
