[Erroneous X-ray dose measurements in paediatric cardiac investigations].
According to national and international rules the x-ray exposure of cardiac catheter examinations have to be measured. For a Philips Integris angiographic system used for paediatric heart catheterization we found severe errors in the indicated time of fluoroscopy and total dose area product ( DAP) both for fluoroscopy and radiography. Fluoroscopy times shorter than 6 seconds and DAPs smaller than 0.1 Gy cm (2) are ignored and not considered in the indicated total fluoroscopy time and the fluoroscopic and radiographic DAPs. This error leads to a systematic underestimation of the risk of radiation-induced cancer especially with infants and children.
