Abstract

Our study takes place in the radiology room of the University Hospital Center (CHU) of Bouaké in the central region of Cote d’Ivoire. The work involved 60 patients, including 30 for the examination of the front chest and 30 for the examination of the front lumbar spine. We used a DAP- meter to measure the dose in the air each time the beam was sent to the patient by the technician medical imaging. By a calculation we were able to obtain the Entrance Surface Dose ESD for each patient and the 75th percentile allowed us to obtain the Diagnostic Reference Level (DRL) for each of the two examinations at the CHU of Bouaké. The comparison of the DRL to the mean dose ESDm allows us to say that the dose is not optimized for the examination of the front chest and that corrective measures are to be taken by choosing appropriately the voltage, the charge, the distance focus detector (DFD) and using a total filtration of at least 2.5mm Al. However, for the examination of the front lumbar spine, although the dose is optimized, we can further increase the voltage and decrease the charge within the limits recommended by the learned societies of radiology, to reduce the dose. The DFD can be increased to 140 cm and also increase the total filtration to at least 2.5mm Al.
