Assessment of Radiation Dose Received during Thoracolumbar and Skull Examinations in Red Sea State Medical centers

ABSTRACT

The main objective of this study was to assess patient dose during x-ray

examination of skull and thoraco-lumbar in Red Sea state Hospitals. The

dose received by 146 adult patients was measured using CALDOSE

software by entering the parameters: focus to detector distance FDD,

mAs , KVP.

The result of the study showed that the mean of ESAK were found to be

(0.79 ± 0.30) for skull and (0.37 ± 0.2) for thoraco-lumbar. The INAK

were found to be (0.52 ± 0.14) for thoracic lumbar and (0.67 ± 0.25) for

skull. The RCI were found to be (0.39 ± 0.19) for skull and (1.04 ± 0.75)

for thoraco-lumbar.

The mean ESAK values obtained are found to be within the

standardreference. The data obtained may add to the available

information in nationalrecords for general use. It may provide guidance

on where efforts on dosereduction will need to be directed to fulfill the

requirements of the optimizationprocess and serve as a reference for

future researches.
