Web20 mrt. 2024 · Transform Physical Point To Index using ITK. I am trying to get HU value along a trajectory. The target coordinates and the tangent to this target (hence the trajectory) are calculated using Matlab on a mesh file, giving a set of xyz coordinates and the direction vector (tangents). WebInitializing the DisplacementFieldTransform using an image requires that the image's pixel type be sitk.sitkVectorFloat64. Initializing the DisplacementFieldTransform using an image will "clear out" your image (your alias to the image will point to an empty, zero sized, image).
