SUMMARY:Biomechanical Imaging in Tissue - Using Time Dependent Data - McLa
 ughlin\, J (Rennselaer Polytechnic Institute)
DTSTART:20111110T140000Z
DTEND:20111110T150000Z
UID:TALK34507@talks.cam.ac.uk
CONTACT:Mustapha Amrani
DESCRIPTION:Biomechanical Tissue Imaging is inspired by the doctor's palpa
 tion exam where the doctor presses against the skin to feel abnormal stiff
  regions within the body.  This talk about this imaging area will contain 
 a description of inventive technologies that utilize the concept of interi
 or radiation force\;  an example of one of these technologies is Supersoni
 c Imaging which is developed in Paris.  In these technologies low amplitud
 e (tens of microns)  propagating wave motion is produced in the body and t
 he technologies output a movie of this motion. We will discuss elastic and
  viscoelastic mathematical models and the essential properties that must b
 e included so that solutions mimic the data produced by the experiment. \n
 \nAlgorithms\, that utilize the fundamental features of the model and the 
 time dependent data\, will be presented.  Images of cancerous tissue\, cor
 roborated with ultrasound images\, including cancerous inclusions a few mi
 llimeters in diameter will be shown. Statistical properties of the images 
 and sensitivity results will be included if time permits.\n\n
