3D volume generation from DICOM images

This code describes different ways of reading DICOM images.

Using 'ImagePositionPatient' attribute

• Function get_dcm reads dicom files from a directory

• It first checks if the DICOM images have ImagePositionPatient attribute. If it has, it stores slices according to the ImagePositionPatient. Otherwise, it sorts by name.

• Input parameter: dcm_path: location of dcm data

• Output: Returns -
  dcm_data: dicom data in a single array
  pix_spacing: spacing of pixel/voxel
  intensity: min and max intensity
  

Using 'SliceLocation' attribute

• Function get_dcm reads dicom files from a directory

• It first checks if the DICOM images have SliceLocation attribute. If it has, it stores slices according to the SliceLocation. Otherwise, it sorts by name.

• Input parameter: dcm_path: location of dcm data

• Output: Returns -
  dcm_data: dicom data in a single array
  pix_spacing: spacing of pixel/voxel
  intensity: min and max intensity
