Hi,
The chances are that you will have better contrast and SNR in the averaged image and so I would run bias field correction on the averaged image. One exception would be if there was very strong bias field in the original images that led to registration inaccuracy - in this case I would run the bias field correction on the original images, if possible.
All the best,
Mark
