Abstract: ZusammenfassungIn der vorliegenden Arbeit wird ein Verfahren vorgestellt, mit dem räumliche Ultraschallbildsequenzen aufgenommen und die Organschnitte zu einem 3D Körper rekonstruiert werden können. Für die folgende Auswertung wurden Tumore der weiblichen Brust aufgenommen, in ihrer texturellen Gewebecharakteristik gekennzeichnet und 3D rekonstruiert. Erste Ergebnisse zeigen, daß sich repräsentative Meßfenster normalen Brustgewebes, von Fenstern innnerhalb des Fibroadenoms und Carcinoms durch ihre textureile G… Show more

Studies on tissue characterization by texture analysis with co-occurrence matrix method using ultrasonography and CT imaging

et al. 2002

We used texture analysis with the co-occurrence matrix method to analyze ultrasonograms from normal and diseased livers, and X-ray CT images obtained from normal cases and cases of idiopathic interstitial pneumonia. Ten cases of normal, fatty, and cirrhotic livers; 10 cases of normal lungs; and 10 cases of idiopathic interstitial pneumonia, all confirmed by clinical findings, laboratory data, surgery, or biopsy, were the subjects of this study. We compared the results of texture analysis in normal and diseased livers under the same conditions of gain, focus, magnification rate, probe frequency, and depth of the region of interest. Here we discuss the relationship between Fisher ratio of texture analysis and pathological character. Although the normal and diseased liver groups did not differ significantly, the different pathological grades of fibrosis and the different size of nodules in the cirrhotic and normal liver groups did have different Fisher ratios. We compared the results of texture analysis with images obtained from normal cases and cases of idiopathic interstitial pneumonia. Significant differences between normal lungs and those with idiopathic interstitial pneumonia were also found. We thus think that texture analysis can be used to analyze ultrasonograms obtained from lesions of different pathological grades and to classify CT images as well.

A system for three-dimensional (3D) presentation of intravascular ultrasound (US) images was designed. A standard hardware configuration based on personal computer equipment was used for acquisition and processing of image data. Pullback imaging with the US catheter was controlled by a specially designed motor assembly and performed either in equidistant 1-10 mm steps or at a constant retraction speed. Curvature of the vessel was documented on biplane digital subtraction angiograms and the US images were arranged according to the vessel shape in the angiograms. 3D reconstruction appears essential for spatial orientation of intravascular US and may be helpful in the planning of vascular interventions for a better appreciation of the extent and morphology of vascular lesions.
