The correction of ultrasonic image analysis features for their depth dependence.
Ultrasound has long been used for clinical imaging purposes and for estimating the properties of tissues. More recently image analysis techniques have been used for quantifying the image's texture. These techniques have had limited success due primarily to the dependence of the texture measures on the depth of the sample volume. A simple algorithm has been developed for deriving a correction for this effect; its efficacy is demonstrated on placental data.
