Effect of different phantom positions in lateral lumbar spine radiography on effective dose and absorbed dose to selected organs

This study aimed to investigate the different positioning of patient in left and right lateral position during lumbar spine radiography its effects on effective dose absorbed for selected organs. The was performed a Siemens Multix/Vertix X-ray unit using Agfa's computer system. Two anthropomorphic phantoms (PBU 60 RS 113T) were imaged both projections with tube voltage from 79 kV 90 kV. measured DAP meter placed under collimator unit. organs calculated Monte Carlo simulation programme PCXMC 2.0. Based calculations, results PBU phantom showed decrease 15.2%, while 113T 14.2% favour projection. An organ significant reduction lymph nodes, pancreas, small intestine, spleen, stomach this results, we can conclude that projection should be method choice when imaging
