PLATFORM FOR THE SIMULATION OF ARTERY The software use for simulation of radial artery is COMSOL.
Why using COMSOL ? Comsol is a software containing multiphysics or cophyisics. physiological model could easily design and Simulate. Is a most advance model designing tool or platform which is incorporated with other fourth generation languages i.e. MATLAB, LABVIEW, SOLID WORKS etc.
STEPS TO CONSTRUCT A MODELSelect the following in sequence: Dimension Add physics (multiphysics) Study type Suitable unit Geometry Material MeshThen finally we simulate the model by computing.
RADIAL ARTERY ANATOMYA major artery that follows the course ofthe radius on the ventral aspect of theforearm to the wrist, where it is felt as apulse, and enters the hand. It suppliesblood mostly to the thumb, indexfinger, and muscles of the forearm.
RADIAL ARTERY BIOPARAMETERS With the help of ultrasound the following observations are found i.e. Depth of radial artery === 3.5mm Diameter of radial artery === 2.3mm Radius of radial artery === 1.15mm
ELECTRICAL CONDUCTIVITYIt is a measure of a materials ability to conductan electric current. Electrical conductivity of following bioparameters found to be: Stratum === 0.0005S⋅m−1 Epidermis === 0 .95S⋅m−1 Dermis === 0.322S⋅m−1 Muscle === 0.66S⋅m−1 Radial Artery=== 0.8S⋅m−1
RELATIVE PERMITTIVITYIt is the ratio of the permittivity of a substance to that of free space or vacuum, relative permittivity is also called dielectric constant. Relative permittivity of following bioparameters found to be : Stratum === 1F/m Epidermis === 31.3F/m Dermis === 31.3F/m Muscle === 1F/m Radial Artery === 1F/m

GRAPH FOR BEST INTERDISTANE BETWEEN ELECTRODES OF RADIAL ARTERY
STANDARD INTERDISTANCE BETWEEN ELECTRODES Best distance that will not effect the surrounding tissues by electric field is found to be 3mm. Fixed electrode size WIDTH= 2mm HEIGHT=1mm

BEST DIMENSION OF ELECTRODES Best dimension of electrodes for electric field that will not effect the surrounding tissues are found to be WIDTH = 2mm HEIGHT =1mm Fixed electrode Distance = 3mm
STANDARD ELECTRODE SIZE Best electrode size to generate electric field without harming surrounding tissues of radial artery is found to be ELECTRODE WIDTH= 2mm ELECTRODE HEIGHT= 1mm
