简要总结
To evaluate the effect on radiation dose using intelligent camera positioning in comparison to manual positioning by the radiology assistant.
详细描述
The positioning of the patient at the beginning of every CT examination has an major influence on the image quality and especially on the respective effective patient dose in the CT scan. If the patient position is closer to the X-ray tube, the patient dose increases significantly and if the vertical patient position is chosen too far away from the X-ray tube, the applied dose decreases, but also the image quality.
In a retrospective observational study, patients were examined on the CT scanner Somatom X.Cite and divided into two groups, one group was with intelligent camera positioning and the other with manual positioning.
The patients received their CT scan at the Institute Radiology and Nuclear Medicine at the Nuremberg North Hospital strictly according to the clinical indication and without influence of the study.
