A novel method in exploration of arteries inside a tissue and assessment of the arteries by computational approach

In the present study, palpating the arteries and tactile distinction of a healthy artery from a stenotic artery whether inside of tissue or out of tissue, using finite element method, are presented. Four models have been created: tissue including a healthy artery, tissue including a stenotic artery, healthy artery out of tissue, and stenotic artery out of tissue. After solving these models with similar conditions and loadings, the stresses in contact area which has key importance for transferring tactile data were explored. It was observed that the stress graph of all of models included a time dependent stress peak. But the value of stress peaks and the difference between maximum and minimum stresses are the criteria for distinction of a healthy artery from a stenotic one. Finally, the rolling of an artery by surgeon´s fingers was modeled and the importance of this work in surgeon´s diagnosis was described.
