Introduction:  Pressure  sores  refer  to  lesions  that  are  produced  while  a  constant  pressure  causes  necrotic  tissue to grow. The need for a better comprehension of the process has led researchers to artificial generation  of  pressure  sores.  Modeling  the  mechanical  behavior  of tissue  will  provide  a better understanding  of this  process as well as a more suitable selection ...

in this paper an automatic examination robot was developed to improve the process of cancer detection, tumor localization and geometrical shape diagnosis. a uniformly distributed compressive load was applied to the top tissue surface and the resultant mechanical stress was measured that was employed for the tumor diagnosis task. the experimental examinations were performed on the soft tissue of...

Background: Autoregulation of blood flow is a marvelous phenomenon balanc- ing blood supply and tissue demand. Although many chemically-based explanations for this phenomenon have been proposed and some of them are commonly used today, biomechanical aspects of this phenomenon was neglected. The biomechanical aspect provides insights to us to model vessel diameter changes more precisely and comp...

Mechanical environment has a crucial role in our organism at the different levels, ranging from cells to tissues and own organs. This regulatory is especially relevant for bones, given their importance as load-transmitting elements that allow movement of body well protection vital organs load impacts. Therefore bone, living tissue, continuously adapting its properties, shape repairing itself, b...

The solution of the Stefan problem for determination temperature fields in biological tissue during cryoablation defined areas with a view to their identification and localization, followed by therapeutic action is proposed. Three types cryoinstruments considers that as first approximation presents one-dimensional problem. Identify three isothermal surfaces reveal zone influence, freezing necro...

Nowadays, one of the main problems encountered in minimally invasive surgery and telesurgery is the detection of arteries in tissue. In this study, for the first time, tactile detection of an artery in tissue and distinguishing it from the tumor has been modeled by finite element method. In this modeling, three 2D models of tissue have been created: tissue, tissue including a tumor, and tissue ...
