Content based medical image retrieval using barcodes

[Raazi]

Hi,

I am doing research in content based image medical image retrieval using radon barcodes. I have replicated an approach found in this paper 277011226_Barcode_Annotations_for_Medical_Image_Retrieval_A_Preliminary_Investigation. I have tried to make some improvements to this process regarding the barcode formation technique. However I wanted to ask if anyone knows the answers to or resources relating to:
a.) Standard preprocessing process for x-ray images, for retrieval tasks?
b.) Is there a process for isolating and reconstructing sinograms from the radon transform of an image. (Ie identifying segments of an image from their corresponding sinograms)?
c.) Is there an optimal technique for forming barcodes from component data blocks?
d.) Is there an optimal technique for comparing two binary vectors to one another? (Hamming distance?)
e.) How x-ray imahes are typically stored in hospital databases? (Imclef?)

I have a engineering background but am new to medical image processing and retrieval so any relevant information would be appreciated.
