Actual behavior:

Hi, I had created the python script that load the series of the DICOM files. the script is follow:

def LoadDicomFile(path=None,NodeName=None):
filelist=os.listdir(path)
progress = slicer.util.createProgressDialog(parent=None, value=0, maximum=len(filelist))
plugin=DICOMScalarVolumePlugin.DICOMScalarVolumePluginClass()
from DICOMLib import DICOMLoadable
loadable=DICOMLoadable()
step=0
for filename in filelist:
loadable.files.append(path + ‘/’ + filename)
labletext = ‘\n LoadDicomFile %s …’ % filename
progress.labelText = labletext
slicer.app.processEvents()
progress.setValue(step)
step += 1
slicer.app.processEvents()
try:
flag = plugin.load(loadable)
except:
print ‘except load false …’
progress.close()
del plugin
del loadable

LoadDicomFile(‘f:/data/’)
but the MPR seem is not good look this… the script have any problems???

You get the file list by calling filelist=os.listdir(path), which returns the files in some random order (how they are ordered in the file system). See this topic about how to do it correctly:

Load DICOM series using python

Hi I am trying to create a python script that can import a DICOM image series from a folder, however I can’t seem to find a way to make this work. I can load a single DICOM file (in my case an RTSTRUCT) using this code: contour_fn = 'contours.dcm' # Add filename to list for DICOM-RT module contour_vtkFileList = vtk.vtkStringArray() contour_vtkFileList.InsertNextValue(slicer.util.toVTKString(contour_fn)) # Examine files contour_loadablesCollection = vtk.vtkCollection() slicer.modules…

Hi! I’m experimenting with controlling 3DSlicer from Jupyter Notebook and I found the initial script useful… I want to share the Python3 version of it since others may end up here:

import os
from glob import glob
from DICOMLib import DICOMLoadable
import DICOMScalarVolumePlugin

def load_dicom_folder(path):
    plugin = DICOMScalarVolumePlugin.DICOMScalarVolumePluginClass()
    loadable = DICOMLoadable()
    for file_path in sorted(glob(os.path.join(path, '*'))):
        loadable.files.append(file_path)
    try:
        flag = plugin.load(loadable)
    except Exception as e:
        print(e)

load_dicom_folder('folderPath')

I removed the progress dialog window, since it’s so fast It’s barely useful nowadays.

You can also find up-to-date DICOM loading examples in the script repository.

I did not find found that page before… the code there is much better
than mine, with the official script in the Wiki the Patient and the
Study are also handled!

Thank you!
