A study of the relationship between patient dose and size in paediatric radiology

摘要: Entrance doses and dose-area products have been measured for paediatric X-ray examinations in a dedicated department. Dose-area barium meal micturating cystourethrogram involving fluoroscopy were substantially less than results from other studies. A number of factors contribute to this, including high gain image intensifier used without grid, shorter screening times, smaller numbers films, exclusive use 100 mm camera careful collimation the field. air kerma has pelvis, abdomen, chest skull radiographs. The relationship between dosimetric quantities an equivalent patient diameter derived data on height weight studied. show linear logarithm entrance radiographic performed single unit. Application exponential correction could allow radiographs children different ages be compared with appropriate reference doses.
