Groupwise Registration of 3D US Images

Hi,

I was wondering if ImFusion has any way of registering multiple 3D US volumes simultaneously.

Hi,

we currently donā€™t have an option for registering multiple 3D volumes simultaneously. What is possible is to register them sequentially with the ā€œImage Sequence Registrationā€.

Hi Markus,

Thank you for your response.

Where can I access this feature, ā€˜Image Sequence Registrationā€™?

I have an academic license, but I canā€™t find it anywhere.

Hi Sewify,

The Image Sequence Registration does not work on multiple individual datasets with one volume each but with one dataset with multiple volumes.

Therefore, you first need to combine your volumes into a single dataset using Image Operations -> Combine Images. This will create a new dataset with multiple volumes. Use the Selection widget to browse the volumes inside.
Then you can run the Registration -> Image Sequence Registration on that combined dataset.
After registration you can run Image Operations -> Split Images to split the combined dataset into individual datasets with one image each.

Alternatively, you can run pairwise regular image registrations on your individual US volumes like this: After you registered 2 volumes successfully, you use the Linking -> Link Pose feature on those two to keep them registered. Then you continue with the next pair of volumes, first register, then add to the ā€œLink Poseā€. Rinse and repeat until everything is registered.

Cheers,
Christian
