Computerized Tomography-Medical and Industrial Applications (CTMIA-13)

Sno National/International Workshop Date Topic Organised by
1 National Workshop 10-08-2013 Computed Tomography Signal Processing Research group

Computed Tomography refers to study of reconstruction of images of 2D-slices of objects. It has applications in medical imaging and non-destructive testing. The fundamentals of computed tomography will be discussed in this talk. Two classes of algorithms will be discussed. One class of algorithms will involve the conventional tomography algorithms such as back projection, convolution back projection, filtered back projection and Fourier Slice theorem based algorithms. The other class of algorithms will involve reconstruction algorithms with a few projections. Since each projection requires some amount of X-ray energy to be transmitted into human body in medical imaging, large number of projections will expose the human body to large amount of radiation. Since X-ray has ionizing effect, exposing to large amount of X-ray may cause some side effects such as cancer. To reduce the side effects due to radiation, it is better to minimize X-ray dose. The second class of algorithms are attempting to reconstruct slice image with minimum radiation. To minimize the radiation, minimum number of projections are taken. Small number of projections will have relatively less information. To compensate the information loss, we make use of some known information about the object. The apriori information that are considered in this talk are known sub image, known similar image, periodicity, local pixel sum etc. The recent trend in Tomography research is minimization of radiation. Many industrial systems have been developed based on X-rays, gamma rays, ultrasound, microwaves and lasers. Many re construction algorithms have been developed for Image re construction. Many Institutions like IISC, Bangalore, BARC, Mumbai ANURAG, Hyderabad, CAT Indore, IIT Kanpur, DL Jodhpur, and DRDL, Hyderabad have developed practical system for their application.

DRDL has developed x-ray based CT system for objects up to 1000mm diameter in which the speaker has direct experience. Many practical problems need to be handled like beam hardening, photon statistics and cupping and diagonal artifacts in industrial applications

In two lectures it is planned to cover industrial tomography with practical case studies
