Magnetic resonance imaging (MRI) simulation on EGEE grid architecture: a web portal design

Area of Science:

• Medical Imaging
• Computational Science
• Grid Computing

Background:

• Magnetic Resonance Imaging (MRI) simulations are crucial for studying MRI sequences and validating image processing algorithms.
• These simulations are computationally intensive, making grid technologies a valuable resource.
• Current grid access for MRI simulation is complex, hindering end-user accessibility.

Purpose of the Study:

• To develop a web portal that simplifies the process of simulating MRI images on the grid.
• To provide a user-friendly interface for researchers to conduct MRI simulations.
• To leverage grid computing for computationally demanding MRI simulation tasks.

Main Methods:

• A three-layer client/server architecture web portal was designed.
• The SIMRI MRI simulator was implemented on the grid using Message Passing Interface (MPI) and LCG2 middleware.
• A Java thread manages simulation jobs, submitting them to the grid and updating their status.

Main Results:

• The web portal successfully enables users to submit MRI simulation jobs via a web interface.
• Users can monitor the status of running jobs and access historical data of terminated jobs.
• Simulated MRI images are automatically sent to the user upon job completion.

Conclusions:

• The developed web portal significantly simplifies grid access for MRI simulations.
• It provides a user-friendly platform for researchers to perform complex MRI simulations.
• This enhances the utility of grid computing for advancing MRI research and image processing validation.
