Energy-selective x-ray imaging and other topics
Topics covered are:
X-ray imaging
Energy Selective x-ray imaging
Computer-assisted diagnosis (future)
Image Analysis and computer vision (future)
A free ebook on the topics discussed in my blog is available. The ebook puts together and organizes all the blog posts in one document. This makes it easier to search for all discussions of a particular topic and to see the relatioships between the posts. There is a table of contents and the pdf has "bookmarks" so it is easy to jump from post to post. So far, the book is over 260 pages.
To get it, email me at
The book is revised periodically. If you want an updated version, email me at the address above.
