DESCRIPTION:The necessity of surgical intervention of abdominal aorta aneur
 ysms is based on a risk-reduction paradigm\nprimarily relying on trans-abd
 ominal ultrasound (US) measurements of the maximum diameter of an AAA. Mod
 el-based\nultrasound elastography\, or elasticity imaging\, is an adjunct 
 imaging technique that can be used to measure changes in the\nmechanical p
 roperties of AAA vessels and potentially provide point of care information
  on the stress within the tissue. Out\nhypothesis is that this information
  may be used by clinicians to improve risk assessment for surgical interve
 ntions. We\npresent results of validation studies comparing modulus recons
 tructions with known solutions are performed from\nsimulations\, experimen
 tal results of tissue-mimicking phantom studies\, and initial clinical res
 ults. We show that our\ntechniques can identify changes in tissue stiffnes
 s that maybe used as a surrogate for the relative health of AAA tissue. I 
 will\nalso discuss the necessary steps for estimating stress in these vess
 els using this technique.\n\nSpeaker(s): Dr. Michael Richards\, \n\nRoom:
