| description | The use of multi-detector row computed tomography in cardiac examinations is
increasing globally. Several hospitals are yet to establish a practical
method for evaluating the extra scattering dose in the lungs (Dlung) of male
examinees with different body-weights undergoing cardiac computed tomography.
To measure the dose in each slice of a lung (Dlung,i), thermoluminescent
dosimeters are inserted into Rando and tissue-equivalent phantoms made of
polymethylmethacrylate and derived from ICRU 48 with masses from 10 to 90 kg.
Dlung was evaluated by weighing the scanned volume of each slice. A practical
method for determining Dlung involves 64-slice computed tomography scans
using a Philips Brilliance computed tomography at 120 kV and 200 mAs, with a
thickness of 1.0 mm. Dlung,i increased with distance from the scanning
region. This experiment yielded Dlung values from 12.1 ± 2.1 mSv (90 kg) to
23.0 ± 3.8 mSv (10 kg). Finally, a simple equation can be used to derive the
relationship between Dlung and the body-weights of a male examinee.
Experimental results are compared with others in the literature. |
