Extract an oblique plane using the direction matrix

I am new to ITK, but was using it to resample my volume into a new direction matrix of (-0.237453, -0.971399, 0.0, 0.971399, -0.237453, 0.0, 0.0, 0.0, 1.0). I would like to get the axial view at a specific mid point. I tried to use python slicing after resampling the volume but it does not work. I was looking at using extract filters but am struggling to see how to do this. The slice I want is shown in the image below as the sagittal view (yellow window).

Thank you
