class_docstr: MINC implementation of array proxy protocol
  
  The array proxy allows us to freeze the passed fileobj and
  header such that it returns the expected data array.
docstr: Read slice `sliceobj` of data from file
docstr_tok: ["Read","slice","`","sliceobj","`","of","data","from","file"]
code: def __getitem__(self, sliceobj):
      """Read slice `sliceobj` of data from file"""
      return self.minc_file.get_scaled_data(sliceobj)

label_desc: Use image node_id 6 for calling the MincImageArrayProxy obj's underlying member method code with example usage: obj.__getitem__(sliceobj) and returns: self
