Distorted Images from DICOM File

[lassoan (Andras Lasso)]

This protocol of acquiring 3 sparse volumes (instead of one high-resolution volume) is very common for musculoskeletal MRI, probably because it saves acquisition time and it is fine for humans to read such images. Unfortunately, these images are not optimal for 3D analysis. See this topic for more details:

Combining volumes - what am I missing?

In general, these multiple low-resolution acquisitions are not well suited for any 3D processing, so the best would be to acquire proper 3D volume, with as isotropic spacing (cubic voxel shape) as possible. You may try to find toolkits that can create an isotropic super-resolution image from multiple low-resolution sweeps, but this is a difficult image reconstruction problem, so there are no standard solutions.
