LITTLE
PRISM USED AT THE COLLIMATOR
|
| |
The
LITTLE PRISM is fixed to the collimator in any position
by means of self-adhesive Velcro® (supplied). Its gradients
are four times smaller at a 100-cm distance, due to magnification
(see brochure).
Lateral decubitus films of D.C. enemas are improved
when covering the upper 10 cm of a flaccid abdomen with the shadow
of the LITTLE PRISM.
The filter is also useful on chests having a wide base, to attenuate
over-penetration of the apexes. Sometimes useful over the thinner
part of some extremities. |

|
|
 |
The
LOWER PATELLA is less penetrated using the LITTLE PRISM.
When the cassette is vertical, use auto-adhesive Velcro®
to hold the filter.
