============================
Maximum intensity projection
============================

Creating a maximum intensity projection of an image volume.

.. GENERATED FROM PYTHON SOURCE LINES 8-13

.. code-block:: Python


    import numpy as np
    import dbdicom as db
    from dbdicom.extensions.numpy import maximum_intensity_projection


.. GENERATED FROM PYTHON SOURCE LINES 14-15

Create some test data, in this case a zero-filled array, describing 8 MRI images each measured at 3 flip angles and 2 repetition times:

.. GENERATED FROM PYTHON SOURCE LINES 15-23

.. code-block:: Python


    coords = {
        'SliceLocation': np.arange(8),
        'FlipAngle': np.array([2, 15, 30]),
        'RepetitionTime': np.array([2.5, 5.0]),
    }
    series = db.zeros((128,128,8,3,2), gridcoords=coords)


.. GENERATED FROM PYTHON SOURCE LINES 24-25

Create a maximum intensity projection

.. GENERATED FROM PYTHON SOURCE LINES 25-28

.. code-block:: Python


    mip = maximum_intensity_projection(series, dims=tuple(coords), axis=0)


.. GENERATED FROM PYTHON SOURCE LINES 29-30

To see what happened we can retrieve the nympy array of the MIP

.. GENERATED FROM PYTHON SOURCE LINES 30-36

.. code-block:: Python


    array = mip.pixel_values(dims=('SliceLocation', 'ImageNumber'))
    print(array.shape)
