Advances in X-ray and Neutron Imaging and Its Applications

Neutrons and X-rays provide a means to peer into the interior of objects, which are otherwise not optically visible. With the development of detector technology and new radiation sources, several new imaging technologies using x-rays and neutrons have emerged and have found widespread applications in industry, material science and medical imaging. The last two decades have seen the development of numerous new radiation-based imaging techniques and applications. The conventional film-based radiography using either x-rays or neutrons, has been replaced with digital imaging technique which has revolutionized the way images are acquired and analyzed. Imaging has expanded its scope from conventional qualitative radiography to quantitative imaging techniques such as image reconstruction for tomography and real time analysis of void fraction in two-phase flow. We have been engaged in the development of several new techniques using neutrons and x-rays and their application from basic to applied research. Some of these have been brought to the level where these technologies have been transferred for commercial production. This paper gives an overview of various techniques, which have been developed by us in the field of x-ray and neutron imaging. X-ray Phase contrast imaging
