SlicerIGT extension’s Volume reconstruction module is developed for this purpose. See for example this demo:

[![](https://img.youtube.com/vi/hIxr9OKBvQ8/maxresdefault.jpg "Reconstruct 3D or 4D cardiac volumes from sparse 2D frame set") ](https://www.youtube.com/watch?v=hIxr9OKBvQ8)

If your ultasound image sequence does not contain position and orientation information for each frame (which is usually the case) then you can use [this script](https://discourse.slicer.org/t/segmentation-of-mitral-valve/14598/10) to add that information and reconstruct the volume.

The script assumes that the ultrasound image sequence is loaded as a 3D volume (each time point is a frame of the volume), so you may either need to load the ultrasound image with enabling `Advanced` option in DICOM module and choose the `Scalar Volume` reader; or modify the script sothat it uses a volume sequence as input (the script will be somewhat simpler, as you don’t need to create a new sequence, just modify volumes in the sequence).
