Rescaling the DICOM images using the RescaleIntercept and RescaleSlope

Hello Everyone,

I am new to the 3D Slicer software and I wanted to know if there is an option to rescale the DICOM images (For example from a Cone Beam CT) using the RescaleSlope and RescaleIntercept. To convert from the normal units found in CT data (a typical data set ranges from 0 to 4000 or so) we have to apply a linear transformation of the data using an equation given as:

hu = pixel_value * slope + intercept

While I can apply this transformation in Matlab, but it requires a lot of time to rescale every *.dcm file. Is there an option in 3D Slicer to do it? or is it automatically applied while loading the data into the software?. I will be grateful for the help.

Thank you.

Rescaling is applied automatically. You can verify this by hovering the mouse pointer over the image and checking the voxel values displayed in the panel in the lower left corner.
