5.4 Guidelines for Pediatric Applications
Allengers typically conducts radiologists (Government-certified) usability studies
that Compare Allengers detector models to the marketed devices. Participate
radiologists have demonstrated that the images acquired using the Allengers
detectors are deemed to be of diagnostic capability.
Additionally, please review the following scientific literatures regarding pediatric
(https://www.ncbi.nlm.nih.gov/pubmed/29064378) and neonates
(https://www.ncbi.nlm.nih.gov/pubmed/23086629).
Furthermore, please review the following link and reduce pediatric technique
factors accordingly: http://www.imagegently.org
As a general rule, next recommendations shall be observed in pediatrics:
 X-Ray Generator must have short exposures times.
 For system operation, AEC must be used carefully, preferably use manual
technique setting, applying lower doses.
 If possible, use high kVp techniques.
Positioning the pediatric patient: Pediatric patients are not as likely as adults to
understand the need to remain still during the procedure. Therefore it makes
sense to provide aids to maintaining stable positioning. It is strongly
recommended the use of immobilizing devices such as bean bags and restraint
systems (foam wedges, adhesive tapes, etc.) to avoid the need of repeating
exposures due to the movement of the pediatric patients. Whenever possible
use techniques based on the lowest exposure times.
Shielding: We recommend you provide extra shielding of radiosensitive organs or
tissues such as eyes, gonads and thyroid glands. Applying a correct collimation
will help to protect the patient against excessive radiation as well. Please review
the following scientific literature regarding pediatric radiosensitivity: GROSSMAN,
Herman. “Radiation Protection in Diagnostic Radiography of Children”. Pediatric
Radiology, Vol. 51, (No. 1): 141--144, January, 1973:
http://pediatrics.aappublications.org/cgi/reprint/51/1/141.
Technique factors: You should take steps to reduce technique factors to the
lowest possible levels consistent with good image acquisition.
For example if your adult abdomen settings are: 70--85 kVp, 200--400 mA, 15--80
