Purpose¶

The module Window transforms the grey values of an image that are ranging in a certain interval.

Details¶

A LUT is defined for the input image values in the following way depending on a window center and a window width:

values smaller than (windowCenter - windowWidth/2) are mapped to imageMin

values greater than (windowCenter + windowWidth/2) are mapped to imageMax

values inside the interval from (windowCenter - windowWidth/2) to (windowCenter + windowWidth/2) are mapped to imageMin + (imageMax - imageMin) / windowWidth * (value - (windowCenter - windowWidth/2))

Values outside the interval are either set to the image maximum or the image minimum and values inside are mapped to the whole range between the image maximum and the image minimum.

Input Fields¶

input0¶

name: input0, type: Image¶

Output Fields¶

output0¶

name: output0, type: Image¶

Parameter Fields¶

Visible Fields¶

Center¶

name: windowCenter, type: Double, default: 2047, minimum: :field:`imageMin`, maximum: :field:`imageMax`¶: Sets the center of the interval.

Width¶

name: windowWidth, type: Double, default: 4095, minimum: 1, maximum: 4096¶: Sets the width of the interval.

Hidden Fields¶

imageMin¶

name: imageMin, type: Double, persistent: no¶: Minimum voxel value of the input image.

imageMax¶

name: imageMax, type: Double, persistent: no¶: Maximum voxel value of the input image.
