Motion estimation and inversion algorithms for elastography with applications to prostate and breast imaging


Elastography imaging is concerned with the measurement and display of tissue strain or with the identification of tissue intrinsic properties from the measured strain in response to a mechanical excitation. Elastography as an imaging modality presents us with a rich and beautiful set of inter-disciplinary problems, and includes tissue actuator design, specific image sequence design, motion estimation from images, viscoelastic parameter estimation from motion, and computational acceleration of these to the level where real-time performance is achieved.

We present our own contributions to elastography, and we will show that, in particular, ultrasound elastography images are better at delineating the prostate than B-mode ultrasound. We also present our experience with ultrasound elastography examination of the breast and with magnetic resonance elastography of the prostate. We will demonstrate the use of elastography-derived deformable models in a prostate brachytherapy simulator and treatment planner. Finally, we will present a survey of projects in the area of ultrasound image guidance for the da Vinci surgical robot for radical prostatectomy and partial nephrectomy.


Septimiu (Tim) E. Salcudean (S’78-M’-79-SM’03-F’05) received the B. Eng (Hons.) and M.Eng degrees from McGill? University and the Ph.D. degree from U.C. Berkeley, all in Electrical Engineering. From 1986 to 1989, he was a Research Staff Member in the robotics group at the IBM T.J. Watson Research Center. He then joined the Department of Electrical and Computer Engineering at the University of British Columbia, Vancouver, Canada, where he is now a Professor and holds a Canada Research Chair and the C.A. Laszlo Chair in Biomedical Engineering. He spent one year at ONERA-CERT (aerospace controls laboratory) in Toulouse, France, in 1996-1997, where he held a Killam Research Fellowship, and six months, during 2005, in the medical robotics group (GMCAO) at CNRS in Grenoble. France. His current research interests are in medical robotics and ultrasound image guidance, elastography, medical simulation and virtual environments. Prof. Salcudean has been a co-organizer of several symposia on haptic interfaces and has served as a Technical and Senior Editor of the IEEE Transactions on Robotics and Automation. He is a Fellow of the Canadian Academy of Engineering and of the IEEE.
