To begin with, the word tomography can be explained with reference to ?tomo? and
?graphy?; ?tomo? originates from the Greek word ?tomos? which means section or slice,
and ?graphy? refers to representation. Hence tomography refers to any method which
involves reconstruction of the internal structural information within an object mathematically from a series of projections.

The projection here is the visual information probed using an emanation which are physical processes involved. These include physical processes such as radiation, wa..............etc

Technological advances in the field of radiation oncology over the last decade have revolutionized care for cancer patients in the US and worldwide. These technological advancements have been both hardwareand software-based. More importantly, however, a major shift in the clinical paradigm exemplifies this ground-breaking change. Innovative approaches incorporating both technological and clinical changes have resulted in a complex and elegant mix of imaged-based approaches using computed tomography (CT)..............etc

Electrical impedance tomography (EIT) is a medical imaging technique in which an image of the conductivity or permittivity of part of the body is inferred from surface electrical measurements. Typically, conducting electrodes are attached to the skin of the subject and small alternating currents are applied to some or all of the electrodes. The resulting electrical potentials are measured, and the process may be repeated for numerous different configurations of applied current.

Proposed applications include monitoring of lung function, dete..............etc

The conductivity σ may be obtained experimentally .
Further we can get ť by using eqn given below
σ = ( n*Qe2 *ť )/me ---------(1)
but ť obtained may not be accurate but we will get an idea of magnitude of ť . In a monovalent metal no of free e- /m3 is equals the no of atoms /m3 . From table we find that relaxation time T is of the order of 10-14 sec .Thus we can..............etc
