Author(s): Ngarama SM and Mohammedb IBNgarama SM and Mohammedb IB
Volume computed tomography dose index (CTDIvol) and the dose length product (DLP) represents an average doses within a scan dose for a standardized CTDI measurement. They are the useful indicators of the dose measurements for a specific examination protocol. In each case dose evaluations were extracted retrospectively and manually from the operating console. CT examination and radiation doses were determined using the General electric (GE) Bright speed 16-slice scanner. Results are presented in terms of the volume computed tomography dose index (CTDIvol) and dose length product (DLP) for head, Chest and abdomen. The 16-slice capacity and tube potential uniform (120 kVp) was used in the centre while tube current was within a narrow range (200-250 mA). The 75th percentile of adult CTDIvol for head, chest and abdomen are 85 mGy, 13.34 mGy and 1.. Read More»
