examinations: an evaluation of dose for grid and non-grid
techniques - Purpose: Radiation doses have been monitored for a
long time, as we are aware that radiation can produce biological
effects. However, there is a limited amount of information
available on patient dose from cervical spine examinations. In
addition, the techniques used are variable between radiographic
departments and even radiographers within one department. The
difference in technique of particular concern is the use of
radiographic grids. While it reduces scatter and improve image
quality, the use of a grid demands increased exposure factors
and dose to obtain the same optical density on the film. Method:
This study investigated the range of doses for lateral cervical
spine examinations in the Hunter and Sydney metropolitan regions
of New South Wales, Australia. Radiation doses were calculated
from X-ray tube output measur
