What are the most significant things I can do to reduce patient dose during fluoroscopic examinations?
Many actions are similar to those recommended in adult procedures: • The patient should be positioned as close as possible to the image intensifier. • The X ray tube should be as far away as possible from the patient table in order to avoid excessive skin dose. • The lowest frame rate acceptable and last-image-hold facility should be used. Further details are available. • Some centres prefer to set a ‘floor’ (a kVp) below which the system will not go, such as 70 kVp for paediatric patients and 80 kVp for adults. • Additional copper filtration also reduces patient dose.
