2.7.1 Pediatric Radiaon Guidelines
When performing pediatric radiaon, you should follow these guidelines:
• Follow the guidelines provided in Radiaon Safety (page 22).
• Do not radiate when it is not necessary. Use a non-ionizing radiaon modality whenever possible
(for example, ultrasound).
• Remove any objects in the beam that are not radiolucent or that are not necessary to perform the
procedure (for example, maresses, pillows, tubes).
• Select the correct paent type and the correct examinaon protocol for the anatomy.
• Select the lowest uoroscopy avor with the lowest dose.
• Posion the detector as close as possible to the paent.
• Use electronic zoom instead of detector zoom.
• Use collimaon as much as possible to protect areas outside the region of interest. Exclude eyes,
thyroid, breast, and gonads when possible. When possible, perform collimaon on the Last Image
Hold image. Use semi-permeable wedges.
• Consider using Fluoro Store as an alternave to acquision.
• Radiate for the shortest me possible, use the Last Image Hold image to review the anatomy rather
than live uoroscopy.
Before you use the equipment for pediatric cases, Philips recommends reviewing generally available
