Abstract :
The Effective atomic numbers Z¬¬eff , Electron density Ne and CT numbers of skeletal muscle relaxants tubocurarine chloride, gallamine triethiodide, pancuronium bromide, suxamethonium bromide and mephenesin for total and coherent, incoherent, photoelectric absorption, pair production in atomic and nuclear field photon interaction have been calculated in the wide region 1keV to 100GeV. The molecular, atomic, electronic cross sections are calculated using mass attenuation coefficient of relaxants obtained by running WinXCOM programme and finally Z¬¬eff , Ne and CT number of the relaxants have been estimated. The Z¬¬eff , and Ne have found to vary with energy and composition of the relaxants and this variation is shown graphically for all photon interaction. Even CT numbers are also not remaining constant with energy. The significance of CT number in visualizing the image of the biological samples is discussed particularly in the low energy region as this region is extensively used in the medical radiology. This helps in cross-sectional image of internal organs in the field of medicine for diagnosing the diseases. The CT number is not only outlining the inhomogeneities of the tissues but also give the direct information of the tissue electron density from which accurate corrections can be made by suitable treatments
