Webb5 aug. 2024 · We can add critical spatial support by extending the ndarray interface with three spatial image attributes: origin: the physical distance in the coordinate system to the center of the “lower left” pixel. spacing: the N-dimensional physical spacing between pixels. direction: an orientation matrix consisting of direction cosines. This would make Webb3 juni 2024 · compute the volume (in mm³) of a single voxel you can compute the count of pixels in each slice, then you multiply your pixels count with pixel spacing, if you can provide the code you used o read your data, with a sample of your Data, with details about the organ you want to calculate the volume for it, then maybe I can help more. – Bilal

WebbThe one resulting in a visually correct image is the correct byte order. As a SimpleITK image is a spatial object, we may also need to provide its origin, spacing, and direction cosine matrix. Without explicit information we can make reasonable assumptions that often work, as shown in the code below. Code ¶ WebbWhen loading the images with SimpleITK, the resulting numpy array shape should be (1, x, y). We recommend you save your images with SimpleITK so that the correct shape is guaranteed. ...
