Grid-controlled fluoroscopy in paediatric radiology

Grid-controlled fluoroscopy has been adapted to meet the specialized requirements of paediatrics. Diagnostic radiology places ever-increasing emphasis on the demand for reducing the radiation dose, combined with the smallest possible loss of diagnostic information in the radiographic images. To meet this demand, Philips developed a system for grid-controlled fluoroscopy, which was introduced about one year ago. Clinical results indicate that this system can reduce the patient dose by as much as 80 %. As paediatric radiology pays particular attention to radiation protection, the demand soon arose for adaptation of the grid-controlled fluoroscopy system to the specialized needs of paediatrics. This article defines the requirements for a development of this type, and presents the results of our laboratory measurements together with the first clinical experience with the new system.
