ABSTRACT

Performance evaluation of computed tomography is not significant in the Republic of Cameroon in general and more particularly in the city of Yaoundé. Therefore, this work aimed to analyze image performances of 05 CT scanners in 05 medical facilities in the city of Yaoundé, by using the Catphan 700 phantom and test procedures of the Atomic Energy Agency. Five quality control tests were performed on each CT-Scanner. All the CT scanners evaluated showed good results and were not disapproved in three of the five tests performed. The difference between the measured spatial resolution for each of the five CT scanners and the spatial resolution specified by the manufacturer was very high. The low contrast resolution of four of the five CT scanners was found low when compared to the low contrast resolution specified by the manufacturers.
