Presentation Transcript

  1. Imaging Retreat 06/01/2005. Image Distortion Correction using Field Maps: Gautham Kuppampatti Biomedical Engineering. Advisor: Dr. E. M. Haacke

  2. Educational Background: • UnderGraduate Degree: Electronics and Communications Specializing in Image Processing. • Final Year Project: Data hiding using Stenography techniques. • Graduate Degree: Biomedical Engineering specializing in Magnetic Resonance Imaging and Image Processing. • Masters Thesis: MR Distortion Correction. • Research Interests: Image Processing, Distortion Correction in MR and Super resolution Imaging. • Projects involved: MR Distortion Correction; Motion Correction using POCS and GP Algorithm, Improving resolution using POCS.

  3. Introduction to MR Image Distortion • MR images helps in the determination of tumor in relation to the surrounding tissues for Surgeries and radiotherapy planning. • However, the exact locations are hampered by the Geometric and Intensity distortions.

  4. Results: Cylinder distortion with Bo=1.5T, R=70mm and Gr of 10mT/m for 10ppm susceptibility difference.

  5. Results: Human Data

  6. Future Research Interests • Try finding new Algorithms to Correct for MR Distortions. • Correcting for Signal Loss due to in homogeneties in EPI and GE Sequences. • Interested in Parametric MR Image reconstruction for my PhD research. • Image Processing and Mathematical Modeling in MRI.
