Abstract:
Diagnostic X-rays are useful in detecting abnormalities within the body. This
Study was performed to estimate radiation dose for adult patients undergoing
cervical spine X-ray examination by using enterance skin dose , in two selected
centers in Sudan which use Computed Radiography (CR).
The entrance skin dose (ESD) received by 50 adults (23males and 27 females)
aged between 20-80 years old was measured using CALDOSE software by
entering the parameters: focus-to-skin distance (FSD) in cm, the charge in mAs,
the tube potential in kV .
The mean ESD calculated were (1.22914 + 0.226471) mGy (0.43241+ 0.235470)
mGy in center A and center B respectively.
The final results showed that The ESD depends and changes with the exposure
parameters (KV &mAs) and changes with weight.
The ESD in the two centers is within the reference level, also Variations were
observed in ESD values among hospitals under study. From this study we
recommended that for all x-ray equipment should be regular maintenance and
quality control tests and to standardize the exposure parameters in imaging.
