Abstract :
Describes position dependent correction algorithms for image processing parameters in ultrasonographic images. The parameters are calculated using the co-occurrence algorithm. By the nature of ultrasound and the rotation of a single element transducer depth- and angle dependencies occur. For angle dependencies a pre-processing algorithm is described. For depth dependencies a post-calculation correction is described
