Abstract:
This research discusses the parameters that affected the optimization of exposure
factors of lumbosacral region. This research found that most important parameter is
weight and it is a significant one and can affected in to selection of exposure
factors of lumbosacral region regardless if the patients male or female and the
selection of exposure factors of AP and Lateral lumbosacral region don't influence
by patients age and length. This research found a number of equations that can be
give the patients the appropriate dose for imaging of lumbosacral region instead of
guessing according to consideration of the patient or using of the exposure chart.
This equations proportion only with the weight, according to it can select the
optimize exposure factors for lumbosacral region. The study consisted of 40
patients, their mean age, height; weight was 39.2±13.8, 166±7.9, 67.2±14.3
respectively. While the average exposure factors for AP concerning the KV and
mAs was 80.5±10.3, 36.9±10.3 respectively. and the average exposure factor for
lateral projection concern KV and mAs was 87.4±5.1 , 44.1±7.
