Abstract:
A series of phantom experiments were performed with the aim of estimating organ doses for patients undergoing conventional X-ray chest and pelvis examinations. The experiments were performed using physical phantoms corresponding to an adult and a 5-year-old child. Mean organ doses and entrance surface dose were measured using TL-dosemeters. The measured organ doses were compared with the data obtained by calculations using available software tools (EDEREX and PCXMC 2.0) based on the computational MIRD-5 stylized models. The differences between calculated and measured doses for organs located fully or partly in the primary radiation beam did not exceed ±33% with the probability of 95% for the tube voltage 60-140 kV both for an adult and a 5-year-old child phantom. This study suggests that EDEREX and PCXMC 2.0 can be used to estimate organ and effective dose for adult as well as pediatric patients undergoing conventional X-ray examinations.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
