Example text

I will provide a little technical background on the sources of these problems and then follow this up with how they can be corrected in ImageJ. Technical background Of the many sources of noise that exist in imaging, a few can be corrected with correct acquisition settings. Others are inherent in the electronics and physical properties of the camera, and cannot be easily fixed. I will first deal with the source of noise that can be remedied with optimizing acquisition: Shot or Poisson noise. Next, we will look at Electronic or Dark noise.

Select Image | Stacks | Images to Stack from the menu. You will now have a single window where every slice represents one image that you took. 3. Create the noise-reduction image by selecting Image | Stacks | Z Project… from the menu and use Average Intensity as the projection type. A thing to keep in mind is the following: when anything moves between the individual exposures, this method will not provide good results. It is possible to correct for simple shifts, but this only works in the simplest of cases.

To open the image, go to File | Open Samples and select MRI stack. This is an MRI stack where every slice is at a different level through the head (the numbers indicate the slice number): The eyes are clearly visible in slice number 6 as two dark orbs on the top of the image. Slice 11 shows the brain within the skull, and frame 16 shows the ventricles as black holes in the middle of the head. Slice 26 shows the top of the head. The area is much smaller indicating that the crown of the head is being reached.
