Abstract
The assessment of image quality and patient dose from computed
radiography for common x-ray examinations namely skull Posterior Anterior
and Lateral , chest Posterior Anterior , lumber spine Anterior Posterior and
Lateral and pelvis Anterior Posterior radiography was perfumed in three
private hospitals in capital Khartoum . image quality evaluated by using
threshold contrast-detail phantom (TO. 20). Assessment obtained by average
scores from four specialist .
This study deals with evaluation of patient dose received by patients
undergoing radiological examinations , Three large hospitals in Khartoum
were selected and 164 patients made up the sample .The entrance surface
doses (ESDs) to patient undertakening four common x.ray examination (skull
PA& LAT , chest PA , lumber spine AP & LAT, pelvis AP) were estimated
using ionization chamber for air kerma measurements . Exposure settings and
patients data were recorded . Result concerning the kilovoltage (KVp) and
tube current (mAs) and focus to film distance (FFD) settings . and the ESD
values were analyzed and compared (by other hospitals) to those
recommended by the EU . discrepancies in the patient doses and techniques
used for the examinations studied were found among the different hospitals
denoting the importance of establishing a national quality assurance
programme and examination protocols to ensure patient doses are Kept as
Low as possible . All the examinations studied fulfilled the EU
recommendations .
The result of image quality show small different between three hospitals
which indicate the routine quality assurance and quality control play
important role in the equipment performance.
