Journal ArticleDOI
Cardiac function estimation from MRI using a heart model and data assimilation: advances and difficulties.
Maxime Sermesant,Philippe Moireau,Oscar Camara,Jacques Sainte-Marie,R. Andriantsimiavona,Robert Cimrman,Derek L. G. Hill,Dominique Chapelle,Reza Razavi +8 more
TL;DR: A framework to estimate local ventricular myocardium contractility using clinical MRI, a heart model and data assimilation, and results on fitting to patient-specific anatomy and assimilation with simulated data are very promising.
Journal ArticleDOI
Registration and tracking to integrate X-ray and MR images in an XMR Facility
Kawal Rhode,Derek L. G. Hill,Philip J. Edwards,John H. Hipwell,Daniel Rueckert,Gerardo I. Sanchez-Ortiz,Sanjeet Hegde,V. Rahunathan,Reza Razavi +8 more
TL;DR: A registration and tracking technique to integrate cardiac X-ray images and cardiac magnetic resonance (MR) images acquired from a combined X-Ray and MR interventional suite (XMR) and results are shown for two patients.
Journal ArticleDOI
Novel Method of Quantifying Pulmonary Vascular Resistance by Use of Simultaneous Invasive Pressure Monitoring and Phase-Contrast Magnetic Resonance Flow
Vivek Muthurangu,Andrew M. Taylor,R. Andriantsimiavona,Sanjeet Hegde,Marc Miquel,Robert Tulloh,Edward Baker,Derek L. G. Hill,Reza Razavi +8 more
TL;DR: The feasibility of using simultaneous invasive pressure measurements and MR flow data to measure PVR in humans is demonstrated and it is demonstrated that this method is safe and feasible in all patients.
Journal ArticleDOI
Intensity non-uniformity correction using N3 on 3-T scanners with multichannel phased array coils
Richard G. Boyes,Jeffrey L. Gunter,Chris Frost,Chris Frost,Andrew L. Janke,Thomas Yeatman,Derek L. G. Hill,Matt A. Bernstein,Paul M. Thompson,Michael Weiner,Norbert Schuff,Gene E. Alexander,Ronald J. Killiany,Charles DeCarli,Clifford R. Jack,Nick C. Fox +15 more
TL;DR: These optimized settings may assist future large-scale studies where 3-T scanners and phased array receiver coils are used, such as ADNI, so that intensity non-uniformity does not influence the power of MR imaging to detect disease progression and the factors that influence it.
Journal ArticleDOI
Validation of a two- to three-dimensional registration algorithm for aligning preoperative CT images and intraoperative fluoroscopy images.
TL;DR: The consistency and robustness of the algorithm when using two similarity measures, pattern intensity and gradient difference, was investigated and both similarity measures produced similar results.
