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.

Little prism also used next to the patient


For the CALCANEUM (or the olecranum), axial view.


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