Hello John, I think I can at least get the ball rolling for you. Here is my understanding of the situation: micro-CT would probably not be your best option if you wanted to image leaf anatomy. CT images based on how translucent materials are to x-rays. In general, this means that CT is best at imaging hard structures and not as good at imaging soft structures. I will admit that I am not very familiar with plant anatomy, but, just based on my day to day experiences, leaves don't feel like they would have any structures that CT would pick up on. Have you considered using MRI instead? MRI images based on the presence of Hydrogen atoms. As a result, it is very good at showing where water is present in a specimen and, therefore, at imaging soft tissues. I have seen MRI used to image plants before, but I am not sure if it could image something as small as a leaf. That is at least my understanding of the situation. Perhaps someone with more experience can provide more details.
