MICCAI 2016 Daily - Wednesday

MICCAI Daily: Where do you work, Odyssée, and what do you do there? Odyssée Merveille: I was PhD student at Paris-Est University. I just finished my PhD. I will defend at the end of November. I start my one year postdoc at the University of Strasbourg, MICCAI Daily: Can you tell me what your work is about and why it is important? Odyssée: The final goal of the project is to provide the scientific community with simulated MRA images. MRA is Magnetic Resonance Angiography of the blood vessels of the brain. We want to provide simulated MRA along with the branches of the blood vessels. It’s really important for the scientific community because, with these images, they will be able to compare their algorithms, like full segmentation algorithms, etc. It’s really important because the data of the ground truths of the brain blood vessels are really difficult to obtain. The doctors have to manually delineate the vessels of the brains, and it’s really complex and long to obtain. If we are going to provide the community with this kind of data, there will be a huge increase for the comparison of this kind of algorithm. MICCAI Daily: What is the medical advantage in that? Odyssée: There are a lot of different algorithms for segmentation and filtering of blood vessels. The hard thing to do is to compare two algorithms. For that we need ground truth. We need to have the exact positions of the blood vessels for each image. MICCAI Daily: Why is it so difficult? Odyssée: Because we don’t have the data to compare. MICCAI Daily: So like many others in this profession, you are chasing data sets to work on? Odyssée: Yes, exactly From Real MRA to Virtual MRA: Towards an Open- Source Framework Odyssée Merveille Presentation 20 MICCAI Daily: Wednesday
