Web16 jul. 2024 · It may seem a bit redundant, but I would like to have your thoughts considering that conversion DICOM to Nifti is the initial step in the creation of a BIDS structure. In short, using ITK based tools (elastix, ANTS, SimpleITK, MeVisLab, and maybe more), I notice that the Direction Matrix I read from DICOMs is different compared ...

Web9 feb. 2024 · Hello everyone! When I try to convert a nifti file to a dicom series with ImageSeriesWriter, I encounter weird behavior when inspecting the results with ITK-SNAP. For a few cases the intensity range shifts from only positive double values in the nifti image to containing negative integer values in the dicom series.

WebNIfTI uses a simple scheme for data scaling. By default, nibabel will take care of this scaling for you, but there may be times that you want to control the data scaling yourself. If so, the next section describes how the scaling works and the nibabel implementation of same. There are two scaling fields in the header called scl_slope and scl_inter. WebThis class generates a sequence of files whose filenames point to a DICOM file. The ordering is based on the following strategy: Read all images in the directory (assuming there is only one study/series) Extract Image Orientation & Image Position from DICOM images, and then calculate the ordering based on the 3D coordinate of the slice.
