Applying the Uniformity Correction to Other Images

You can estimate the bias field from one image, and apply the correction to another image. This might be useful where the second image has much poorer signal-to-noise ratio, or an unusual contrast that makes it difficult to estimate the bias field. Application of a previously-found correction is also very quick, so this could save considerable time in cases where you have multiple images of the same subject with identical scan plane positioning.

Saving the Bias Field to Disk

To save an image of the bias field estimate to disk, ensure that the check-box is ticked. Now, when you perform the correction, an image of the bias field will be saved to an image with the same name as the input image but with the suffix "_Bias" appended to the name.

Applying Correction Parameters to Another Image

To apply the bias field estimate to another image, ensure that the check-box is ticked and then load the bias field image into the image selection panel below:
