Parameters setting of slice_acquisition()

[Leong1230]

Hi, I would like to use the slice_acquisition() function to extract 2D slices from a 3D volume, but I am unsure about how to properly configure the input parameters.

I have a 3D volume with the following properties:
Size: 𝑁×𝐻×𝑊
Spacing: (𝑠𝑥,𝑠𝑦,𝑠𝑧)
Orientation matrix: 𝑀 (3×3)
Origin: (𝑥,𝑦,𝑧)

I would like to extract a 2D slice of size 𝐻1×𝑊1, with spacing (𝑠𝑥1,𝑠𝑦1) using the slice_acquisition() function and a known transformation matrix 𝑇 (4×4), which implements the same function as:

resampler = sitk.ResampleImageFilter()
resampler.SetOutputDirection(slice_orientation])
resampler.SetOutputOrigin(slice_origin)
resampler.SetOutputSpacing(slice_spacing)
 resampler.SetSize(slice_shape)
resampler.SetInterpolator(sitk.sitkNearestNeighbor)
# Resample the volume on the arbitrary plane
 sliced_image = resampler.Execute(volume)

Thank you!
