The Dose-Right Dose Modulation, or
DOM, technique (Philips Medical Systems,
Eindhoven, the Netherlands) of angular
modulation also adjusts tube current
in asymmetric anatomic regions.
This technique is based on the premise
that tube current should be modulated
according to the square root of the measured
attenuation for that projection (1).
The DOM technique modulates the current
within a 360° tube rotation according
to the square root of the attenuation
measured from the similar and previous
180° or 360° views. In other words, the
attenuation measured at an angular view
