Abstract:
Conventional radiography or X-ray is part of diagnostic imaging tool for
detection and diagnosis of diseases. Since the X-ray was discovered in 1895 to
2010 more than 5 billion medical imaging studies were published worldwide.
However, there are certain harmful biological effects were recorded; for that
the concept of quality control and radiation protection was developed to
minimize these effects.
But now in most of developing countries there is lack of awareness and
interest of radiation protection and quality control in radiology department
even sometimes there is no QC tools, which can lead to improper dose, risk to
the machine, error in reading and image quality.
The present study had been carried out to evaluate the radiation protection
and quality control measures in 15 radiology department in Khartoum state. Data
had been collected divided in to two main parts, first part radiation protection tests,
which include visual inspection test, room dimension, and scattered radiation.
Secondly quality control tests which include output accuracy, linearity,
reproducibility, collimator, filtration, beam alignment. The data were processed,
analyzed and compared with standard tolerance of radiation protection and
quality control test to determine whether these units comply with standards or
not, and suggest any modification should be necessary to correct the observed
defects.
The result of this study showed that, the average of acceptable percentage in
all the units was 70% and 74% in radiation protection test and quality control test
respectively. This percentage generally acceptable for all units.
