Fast model based segmentation of ultrasound data using an active image

Abstract: In the present paper we propose a method for fast segmentation of ultrasound data. It is based on setting up a model depending on user input. We apply a matching scheme in order to obtain initial contours for 2D segmentation of several cross-sections of the organ by a discrete dynamic contour. Further, we set up an active image which drives the deformation of the dynamic contour. The active image comprises both iexiuml information based on image data as well as spatial information which we derive from the init… Show more

“…They can be used for the delineation of multiple objects in an image, whereas the parametric active contours are not so flexible to allow topological changes of the contour during its evolution. The utility of the level set approaches in medical image segmentation is becoming clear in various medical applications such as in the automatic quantification of the ventricular function [23], in prostate [24] and in cardiac ultrasound image segmentation [25]. A state of the art level set approach to image segmentation is the Active Contour Without Edges (ACWE) model [26].…”

“…Εφαρμογές παραμετρικών ενεργών περιγραμμάτων περιλαμβάνουν τον εντοπισμό και την διαγράμμιση ηπατικών όγκων [167], τη διαγράμμιση της διατομής αγγείων σε ενδοαγγειακές υπερηχογραφικές (intravascular ultrasound-IVUS) εικόνες [172], και την αποτίμηση των ορίων κακοηθών όγκων του στήθους [173] για τη διεξαγωγή βιοψίας υποβοηθούμενης από αναρρόφηση (mammotome). Εφαρμογές ενεργών περιγραμμάτων διατυπωμένων με χρήση ισοϋψών περιλαμβάνουν την κατάτμηση υπερηχογραφικών εικόνων καρδιάς [174], προστάτη [175], και την αυτόματη ποσοτικοποίηση της κοιλιακής λειτουργίας [176]. Να σημειωθεί ότι μέχρι τον χρόνο έναρξης της εκπόνησης της παρούσας διατριβής δεν είχε προταθεί κάποια μέθοδος κατάτμησης υπερηχογραφικών εικόνων θυρεοειδούς.…”

“…Parametric active contour applications include the detection of hepatic tumors [5], the detection of lumen and media-adventitia border in sequential intravascular ultrasound (IVUS) frames [6] and the evaluation of margins for malignant breast tumor excision through mammotomes [7]. Level set active contour applications include the automatic quantification of the ventricular function [8] and the segmentation of prostate [9] and cardiac US images [10]. To the best of our knowledge there has not been proposed any information technology approach to thyroid nodule detection in US images.…”
