I've recently started pursuing PhD in Medical Image Processing. I am struggling to find a suitable problem to carry out research.
I was initially interested in working on brain images but after doing studies and according to peers' advices lots of works have already done with brain, but still work can be done on:
1. Retinal images
2. Chest radiography
3. Estimating probability of lung cancer etc.
I would be obliged if somebody suggests me some relevant topics(related to brain or other organs) where still there are lots of scopes to work on.
