Abstract

In a clinical pilot study radiofrequency echograms were acquired during routine echography of intraocular tumours. The data acquisition was performed with an "add-on" device, which was developed at our laboratory. The acquired data were pre-processed to remove the effects due to equipment performance and beam characteristics. The analysis was performed in the frequency domain (acoustospectrography) and acoustic tissue parameters like the attentuation coefficient and backscatter cross section estimated. In addition the gray level statistics of B-mode images were analysed. A set of parameters was thus obtained which was subjected to a discriminant analysis, based on a classification of the tumours by histology (i.e. after removal of the eyes). The results show a significant discriminability between different tumours and even between histological types of the same tumour (choroidal melanoma).
