The high number of overexposed images indicates significant potential for dose reducing radiation doses for patients. In women, there is a particular room for improvement in collimation, particularly in the lateral and caudal regions. Since parts of the mammary glands, which are considered to be radiation-sensitive tissue, are often located in the lateral overexposure areas, this is of particular relevance. In the caudal areas, the stomach and colon are located as radiation-sensitive organs.

Effects of scattered radiation, resulting from overexposure, could not be mapped in this study design. If it bypasses the patient without attenuation and reaches the stand, it is expected to be particularly intense. Further studies on the phantom are required for this.

Limitations: Not all included X-rays displayed all four collimation boundaries, which may cause an underestimation of the actual exposed area and, consequently, the overexposure. In some images, parts of the MinFS were outside the AEA due to a skewed image. In these cases, the total overexposure was still determined, but the lateral overexposure was set to 0.
