Principles of Computerized Tomographic Imaging
An electronic copy of the classic text on Tomographic Image Reconstruction by Avinash Kak and Malcom Slaney.
Individual chapters are available as pdf files (some are quite large). Beware this is an advanced text.
-
Mathematics and Physics of Emerging Biomedical Imaging
This book (from National Academy Press) introduces the frontiers of biomedical imaging, especially the imaging
of dynamic physiological functions, to the educated nonspecialist. Even though published 1996 still a remarkably
contemporary overview of the major biomedical imaging modalities. Suitable as a source book for further research and
education.
-
RadioGraphics
A journal owned and published by the Radiological Society of North America devoted to
continuing medical education in radiology. Contains a plethora of readable, but comprehensive, articles on all issues of medical
imaging (technology, procedures, safety and professional). Free access is available for all articles published more than one year ago.
-
X-Ray Mass Attenuation Coefficients
Reference data from the Physics Laboratory of the National Institute
of Standards and Technology (NIST).
-
LearnCT: Java Sim CT sim application
This rather nice Java based application may be of use to those wishing to gain an intuitive understanding of image reconstruction using
projections. Lots of nifty windows and menus but not much documentation and thus will require a bit of effort to use as intended. Requires user
to download the application (written in Java) in order to use.
X-Ray & X-Ray Computed Tomography
-
X-ray production Describes the physical processes and principles behind
X-ray production.
-
X-ray generators Outlines the operational principles and functional
components involved in the generation of X-rays.
-
CAT Scans
A basic but entertaining introduction to the principles of tomographic image reconstruction of X-rays. Has quite a few nice
applets that allow the viewer to experiment with various parameters such as projection angles and numbers. Recommended for those
bewildered by the mathematics of filtered backprojection.
-
Cone beam reconstruction using filtered backprojection
A PhD thesis that deals with ``with three-dimensional image reconstruction algorithms to be used in future generations of tomographs
with even more detector rows than found in current multi-row systems''.
-
Electron Beam CT
There does not seem to be much technical information on electron beam computerised tomography (also know as Ultrafast® computed
tomography) freely available because most of the technology is proprietary. GE Healthcare is the only player in the EBCT
market following its purchase of the technology pioneer Imatron Inc in 2001.
-
Computed Medical Imaging Godfrey N Hounsfield's 1979
Nobel lecture in which he describes some of his early experiments that led to the development of the technique of computed
tomography. Principally of historical interest.
-
ImPACT Group Website for the UK's CT evaluation centre. A good repository of slides and resources on CT.

3D Virtual Colonoscopy
Advanced volumetric imaging techniques have been used to render helical scan CT data to achieve virtual imaging and exploration of the human colon
(from the Departments of Radiology and Computer Science at SUNY Stony Brook).
-
Visible Human Project®
The Visible Human Project of the National Library of Medicine involves the creation of complete, anatomically detailed, three-dimensional
representations of the normal male and female human bodies using transverse CT, MR and cryosection images of representative male and
female cadavers.
-
e-Anatomy - Atlas of Human Anatomy An excellent site which comprises an interactive MRI
(with various weightings) and CT atlas of the human body. Available in a number of languages. Registration (free) required in order to
view all anatomical labelling.
-
MedPix® medical image data base A peer reviewed data base of medical images and radiology teaching
files. The web interface is a bit clunky and ugly - but definitely worth a look.
