The study aimed to determine how the effective dose (ED) in lumbar spine X-ray examinations is influenced by patient positioning considering the X-ray tube heel effect. The study used Monte Carlo simulation of the effective dose. Using the heel effect, positioning of the patient in the head to anode direction reduces the effective dose by 5% when compared with the head to cathode positioning.
