Using simple scripts to process data in 3dslicer

open slicer Bring it with you Python Interactor . Can pass , menu bar “View” Medium “Python Interactor” open , You can also directly click Python Icon .

How to use it Python Scripts do something interesting

Edit code , Press enter to run .

>>> import qt
>>> button = qt.QPushButton("Test Button")

 Slicer Will create a window and add a Button Control on it , Try clicking on this Button.

  Add a mouse pointing Button Prompt of tense

>>> import qt
>>> button = qt.QPushButton("Test Button")
>>> button.show()
>>> button.toolTip = "This is a Button!"
>>> button.show()

Add one ComBox Control .

>>> comboBox = qt.QComboBox()
>>> comboBox.show()

  This seems to be nothing .

Make a change , towards ComBox Add items to ：

>>> comboBox = qt.QComboBox()
>>> comboBox.show()
>>> comboBox.addItem("first")
>>> comboBox.addItem("second")
>>> comboBox.addItem("third")
>>> comboBox.show()

  Now there is .

Adding script code to the interactive device can not only generate some controls, but also do some simple data processing .

>>> import SampleData
>>> import numpy as np
>>> volumeNode = SampleData.SampleDataLogic().downloadMRHead()
>>> histogram = np.histogram(arrayFromVolume(volumeNode),bins=50)
>>> chartNode = slicer.util.plot(histogram,xColumnIndex = 1)
>>> chartNode.SetYAxisRangeAuto(False)
>>> chartNode.SetYAxisRange(0,4e5)

The processing effect is shown in the following figure ：

To sum up ：3DSlicer In the Python The interposer can facilitate developers to conduct simple tests , However, it is not recommended to use this interleaver for plug-in development , Because once the tester closes slicer, The following script code will be cleared automatically , The controls you generated will no longer exist .
