Research summary

You might be familiar with tomography from medical imaging - it is a technique for looking inside bodies from different angles without cutting them open first. While a photograph is formed from reflected light and an x-ray image from transmitted x-rays in one plane, a tomographic image is formed from measurements taken in many different planes or from different angles.

Medical tomographic imaging really began with the invention of the x-ray computerized tomography scanner by Sir Godfrey Hounsfield (The Nobel Prize in Physiology or Medicine, 1979). The best known example of tomography is a CAT (Computer-Aided Tomography) scan. There are lots of real world problems where you might want to use this technology. In the medical case x-rays can be used to look inside a body from many angles and the tomography part is reconstructing the image of the inside of the body. Tomography lets you look inside a box without opening it.
