Vessel Deformation Bug

[faberno]

Describe the bug
Structure Deformation should only be along the z-axis but vessels are also deformed along the x and y axis.

Specify a priority (low, medium, high)
medium

To Reproduce
Run minimal optical example:
Current behaviour:

Intended behaviour:

The vessel should have the same thickness along the axis.

To increase visibility of the bug, increase maximum_z_elevation_mm in volume_creation_module_model_based_adapter.py

Environment (please complete the following information):

• OS: Ubuntu 22.04
• SIMPA 1.0

Additional context
The bug is caused by applying the deformation to all 3 axes in CircularTubularStructure:
deformation_values_mm = deformation_values_mm.reshape(self.volume_dimensions_voxels[0],
self.volume_dimensions_voxels[1], 1, 1)
deformation_values_mm = torch.tile(torch.as_tensor(
deformation_values_mm, dtype=torch.float, device=self.torch_device), (1, 1, self.volume_dimensions_voxels[2], 3))
deformation_values_mm /= self.voxel_spacing
target_vector += deformation_values_mm

Fix: only apply deformation to z axis
deformation_values_mm = deformation_values_mm.reshape(self.volume_dimensions_voxels[0],
self.volume_dimensions_voxels[1], 1)
deformation_values_mm = torch.tile(torch.as_tensor(
deformation_values_mm, dtype=torch.float, device=self.torch_device), (1, 1, self.volume_dimensions_voxels[2]))
deformation_values_mm /= self.voxel_spacing
target_vector[..., -1] += deformation_values_mm
del deformation_values_mm
