Penfield FusionMultiple measurements. One brain.

Penfield Fusion is multimodal brain imaging and neural-data software. Its purpose is to bring data from many measurement types into one unified, patient-specific 3D brain model.

Every scan is registered, segmented and placed into a shared patient coordinate space, so a researcher can move between modalities without losing where they are.

Separate the brain.
Keep its relationships.

Fusion’s signature view separates brain structures in 3D while preserving their spatial relationships. Explode the anatomy to see how it fits together. Isolate, hide, fade, label and measure each structure, then reassemble it into one brain. Everything below is the working build, captured, not illustrated.

Every structure.
Its own object.

In Fusion, anatomy is not just a picture. Each structure exists as an object that can be inspected, isolated, measured or hidden, including the things that should not be there.
