[Value of physical parameters and digital signal processing in tissue differentiation].
It was the aim of this study to improve tissue characterization using ultrasonic scatter signals and image processing procedures by computer. Analysis of various tissue probes and phantoms showed that structures can be differentiated by scatter as a function of frequency and angle of scatter. The application of this method as an imaging system was realised by a reconstruction algorithm to compute scatter images. By means of analysing images of the thyroid and prostate we found that the detection rate of computerised texture analysis is much higher than that of visual evaluation.
