3. PLATFORM FOR THE SIMULATION
OF ARTERY
The software use for simulation of radial
artery is COMSOL.

4. 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.

5. STEPS TO CONSTRUCT A MODEL
Select the following in sequence:
 Dimension
 Add physics (multiphysics)
 Study type
 Suitable unit
 Geometry
 Material
 Mesh
Then finally we simulate the model by
computing.

6. RADIAL ARTERY ANATOMY
A major artery that follows the course of
the radius on the ventral aspect of the
forearm to the wrist, where it is felt as a
pulse, and enters the hand. It supplies
blood mostly to the thumb, index
finger, and muscles of the forearm.

7. 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

8. ELECTRICAL CONDUCTIVITY
It is a measure of a material's ability to conduct
an 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

9. RELATIVE PERMITTIVITY
It 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

13. 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

17. 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

18. 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
