IPRPI Workshop On Biomechanical Imaging,
April 27 & 28, 2011

Location: Blitman Residence Commons

Workshop Description:      

Recent advances in biomedical imaging have made it possible to image mechanical properties of tissues. These include properties such as the Young’s modulus, nonlinear elastic properties and viscoelastic and poroelastic properties. Simultaneously, it has been established that the mechanical properties of tissue are altered if it is diseased. For example, cancers often present as lumps that are stiffer than their surroundings. Based on this, medical practitioners are now evaluating the potential of biomechanical images in the detection and diagnosis of several diseases such as breast and prostate cancer, atherosclerosis, deep vein thrombosis and liver cirrhosis. In addition, biomechanical images may also be used to generate patient-specific models for surgical training and planning and to test fundamental hypotheses on the effect of mechanics on biology (mechanobiology). 
Almost all techniques in biomechanical imaging involve “watching” the tissue deform using a standard imaging modality such as ultrasound or MRI, and then using the pre- and post-deformation images to estimate the interior displacement of tissue. This displacement data is then used along with an appropriate mechanical model (say linear elastic) to determine the spatial distribution of the desired mechanical property. The problem of determining the spatial map of the mechanical property given the interior displacement data is naturally posed as an inverse problem. What makes this inverse problem special is (1) The availability of (incomplete) interior data. Though displacements are known in the interior of the tissue they are typically known only over a subset of the total domain, or only a single displacement component is known. (2) In solving the problem more than one material property may be sought. For example one may want to image both the linear elastic and viscoelastic parameters. (3) While it may be possible to gather data over a large subset of the domain, it is very hard to generate more than a few (2-3) independent measurements. All these factors (incomplete interior data, multiple solution variables and few independent measurements) make the resulting inverse problem very different from typical inverse problems found in imaging. With this as background, we are proposing a workshop where a few (say five) leaders from the field of biomechanical imaging will present the state of that art and pressing needs in their areas to an audience comprising mainly of applied mathematicians and computational scientists. The hope is that through this interaction the group will identify open problems and in the long term this would lead to greater progress in this new and exciting area of medical imaging.

This workshop is supported by the Division of Mathematical Sciences at the National Science Foundation, NSF DMS-0852516.

Program for the Workshop:

The workshop will run for one and a half days. The workshop will begin at lunch time on the first day and will end at 6 p.m. on the second day. There will be six invited talks, a poster session, and two tutorials.
