» Numerical modeling of ElectroMagnetic field distribution in human tissues
| Short description |
| This project aims at the dosimetric calculation with high accuracy and resolution of the Ultra Wide Band (UWB) signals propagating inside human body. Precise representation of the ElectroMagnetic field distribution in human tissues can be achieved by numerical modelling with realistic heterogeneous models of the human body. 1--2 mm digital human phantom from MRI data is used for the radio environment setting. The works currently available reveal that propagation characteristics depend on the frequency of interest and the radio environment of interest and Ultra Wide Band (UWB) signals penetrate deeper and deposit less energy than the Continuous Wave. This project investigates the propagation characteristics of the UWB signals in human body for medical imaging, in-body and on-body communications and health and safty issues for the mobile phone usage for both adults and children. |

| Goal and potential impact of porting the code to a grid |
| With the rapid and wide spread of the application of the mobile telecommunication, the concern on the adverse health effects of the exposure to signals emitted from devices such as mobile phone is increasing. Exposure assessment in humans ideally is performed experimentally. However, the logistics of an experimental assessment become extremely tedious and volunteer studies are normally viewed as ethically unacceptable. Therefore precise representation of the ElectroMagnetic field distribution in human tissues can be achieved by numerical modeling with realistic heterogeneous models of the human body. Understanding of the UWB propagation characteristics in such a wide range of radio environments can be achieved by the simulation of transient wave propagation. Given the computational resources available, the research derived from the grid based calculation will give the much more precise information than currently available to the community of the medical imaging, health-safety and UWB communications. |
| Targeted use case |
| The user of the application should be able to execute the Fortran90 and MPI programs of the simulation code on the EGEE grid infrastructure. |
| Chosen infrastructure and method |
| The Grid Application Support Team provides technical assistance to execute the MPI and Fortran90 components of the application on the Biomed virtual organization of the EGEE grid. The MPI execution considers the recommendations of the MPI Technical Coordination Group of the EGEE Project. |
