A lot of the medical imagery has to do with my own biography. I had open heart surgery, I had knee replacements, I had a hiatal hernia, etc. Every time you go for surgery, you get a whole spectrum of imaging. Of course, I've been doing research in imaging technology across the board for close to twenty years. When you think about it, medical imaging is actually quite new. The first major medical image was the x-ray in 1895. That was the first time you got imaging of anything that's in the bodily interior.
