[Question] windowing setting value of CT slice image

[Question] windowing setting value of CT slice image

I request the windowing setting value of CT slice image stored in tif file.

You clearly stated in the notice that you used abdominal soft-issue windows (width/level: 350/40).

However, the value is wrong. Please announce the exact value again.

My guess is that the windowing level is -350 and the width is about 1400.

Please release the preprocessing code when you saved the tif.

The abdominal soft-tissue windows were exclusively used for images that were presented to radiologists. The window width and level for the training image is 1400 and -300.

''' def normalize(image): # Normalize image between 0 and 1

MIN_BOUND = -1000.0
MAX_BOUND = 400.0

image = (image - MIN_BOUND) / (MAX_BOUND - MIN_BOUND)

image = image.astype(np.float32)
image[image>1] = 1.
image[image<0] = 0.
return image
