PROVEN LOW DOSE IMAGING Very much detail, high dose Much detail, low dose
While standard patient doses have
been lowered significantly over HD resolution HD resolution with Ultra Low Dose
the years, the pioneering Planmeca
Ultra Low Dose™ imaging protocol voxel size 150 µm, patient dose ~134 µSv voxel size 150 µm, patient dose ~32 µSv
further allows lowering effective
patient doses. It can be used with all Much detail, moderate dose Much detail, low dose

to capture 3D images at a significantly Normal resolution Normal resolution with Ultra Low Dose

All this can be done without a statisti- voxel size 200 µm, patient dose ~86 µSv voxel size 200 µm, patient dose ~20 µSv

The Planmeca Ultra Low Dose
imaging protocol’s effectiveness has Low dose resolution Low dose resolution with Ultra Low Dose
been confirmed in a scientific study
led by the renowned radiologist voxel size 400 µm, patient dose ~30 µSv voxel size 400 µm, patient dose ~6 µSv
Dr. John Barrett Ludlow. The study’s
conclusion states as follows:

“An average reduction in dose of
77% was achieved using ULD protocols
when compared with standard
protocols. While this dose reduction
was significant, no statistical reduction
in image quality between ULD and
standard protocols was seen. This
would suggest that patient doses can
be reduced without loss of diagnostic
quality.” (Ludlow, John Barrett and

Diagnostic FOVs Using Low Dose CBCT

KNOWLEDGE IS POWER
Attentive clinicians can see differences
in image quality for themselves, but
they still need to rely on others to tell
them what the effective patient dose
is. Not all manufacturers can reliably
provide users with such information

Planmeca can give prospective and
existing customers clear information
on the effective patient doses of its
CBCT units. The Planmeca Ultra Low
Dose protocol allows our units to
achieve doses so low that some of our
competitors do not want to believe it.

When shopping for a CBCT unit,
be sure to exercise your right to
receive all necessary information on
the product. Always ask for accurate
info on patient doses and compare the
difference in image quality between
standard and low dose images. ▟
