Objective
Among the AFib patients underwent RF ablation, the relative high AFib recurrence rate is a concern. We combine both the image and shape information for the purpose of predicting the RF ablation success rate.
Approach, Plan
The fibrosis distributions on the left atrium wall is imaged using the dynamic contrast enhanced MRI. Distributed on different anatomical 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 ready
Delivery Mechanism
This work will be delivered to the NA-MIC Kit as a commandline extension.
