dc.description.abstract |
In this study, Entrance Surface dose (ESD) were estimated for adults patients undergoing common X ray examinations in two Hospitals in Khartoum, namely Khartoum teaching hospital and academy teaching hospital. the study was performed in four X ray machines.
A total of 191 patients were included in this study. Patient’s data such as (age and weight) and exposure parameters (kV and mAs) were recorded.
The results of ESD have been obtained with the use of the Dose Cal software which developed by the radiological protection center in saint gorges hospital London.
The results showed that the mean values for chest, abdomen and limbs were 0.31 mGy, 2.6 mGy, 0.05 mGy respectively.
the results obtained in this work range from (10.3) for lumbo_sacral lat to (0.004) for Elbow was not exceeding the reference value and also the values obtained by Previous studies as shown in table (4-40) ,but When compared between the four machines by selected some tests, the mean dose value at Khartoum teaching hospital by (shimadzu (1)) was found to be higher than other machines this me be for these reasons because it is old one and also it is output greater than outputs of other machines,but in general the efficiency of technicians in Khartoum teaching hospital less than in the academy teaching hospital, and also the number of patients in this hospital is more than academy hospital. |
