Load DICOM series using python

Hi Ben,

There are many convenience functions just for this in DICOMUtils. So you don’t need to go through the logic classes:

Slicer/Slicer/blob/master/Modules/Scripted/DICOMLib/DICOMUtils.py

import os
import vtk, qt, ctk, slicer
import logging

#########################################################

comment = """

  DICOMUtils is a collection of static-like DICOM
  utility functions facilitating convenient scripted
  use of the DICOM database

def loadPatientByUID(patientUID):
  """ Load patient by patient UID from DICOM database

I see you want to load RT data. The code form this automated test might help:

github.com

SlicerRt/SlicerRT/blob/master/DicomRtImportExport/Testing/Python/DicomRtImportTest.py

import os
import unittest
import vtk, qt, ctk, slicer
from slicer.ScriptedLoadableModule import *
import logging

class DicomRtImportTest(unittest.TestCase):
  def setUp(self):
    """ Do whatever is needed to reset the state - typically a scene clear will be enough.
    """
    slicer.mrmlScene.Clear(0)

    #TODO: Comment out
    #logFile = open('d:/pyTestLog.txt', 'a')
    #logFile.write(repr(slicer.modules.DicomRtImportTest) + '\n')
    #logFile.write(repr(slicer.modules.dicomrtimportexport) + '\n')
    #logFile.close()

  #------------------------------------------------------------------------------
  def runTest(self):
