Objective
Among the AFib patients underwent RF ablation, the relateive high AFib recurrence rate is a concern. The correlation between the cure/recurrence ratio with the distribution of the fibrosis would provide insight on the disease assessment and treatment planning.
Approach, Plan
The fibrosis distributions on the left atrium wall is imaged using the dynamic contrast enhanced MRI. Distributed on different anotomical structures, they are considered as "mass" defined on different domains. Under the framework of the optimal mass transport (OMT), the masses are transported to a common domain where the statistical analysis can then be applied. The significant different regions are then characterized by the low-p-value regions.
Progress
C++ code using ITK and VTK has been available.
Delivery Mechanism
This work will be delivered to the NA-MIC Kit as a commandline extension.
