Abstract
|
|
|
Purpose : To minimize an unnecessary radiation dose which might affects to medical staffs or patient guardians who stay aside a patient in a CT room. This study was evaluated by a metric of the effective dose and surface dose.
Materials and Methods : This study was performed with a water phantom and anthropomorphic body phantom (Atom) using 16- channel MDCT (Somatom, Sensation, Siemens). The metrics were designed into two categories which one is a scan with protection equipment (Lead Apron) and the other is without the protection. Also, radiation doses were measured at various distances from X-ray exposure spot.
Results: The absorption rate of the surface dose and absorbed dose were highly reduced with the protection equipment and over 1 meter from X-ray source spot. Also, the effective dose was reduced significantly.
Conclusion : It is clear that the both absorbed and surface dose were reduced by the proper protection equipments (Lead Apron and Thyroid guard) and 2 meters distance from X-ray exposure spot. It is an essential factor that we have to provide the proper protection to medical staffs and the patient guidance to minimize unnecessary radiation dose.
