Synergistic MR-PET image reconstruction

Zhaolin Chen, Viswanath P. Sudarshan

Multimodal imaging systems incorporating PET and MRI acquire both functional and structural information to improve clinical diagnosis, therapy, and scientific studies in neurology and oncology. PET and MRI images have different contrasts and different intrinsic spatial resolutions however sharing the same fundamental anatomical structures.

Leveraging mutual information from PET and MRI, this project aims to develop synergistic MR-PET image reconstruction to improve both MRI and PET image quality.
