Texture Analysis of Supraspinatus Ultrasound Image for Computer Aided Diagnostic System
OBJECTIVES In this paper, we proposed an algorithm for recognizing a rotator cuff supraspinatus tendon tear using a texture analysis based on a histogram, gray level co-occurrence matrix (GLCM), and gray level run length matrix (GLRLM). METHODS First, we applied a total of 57 features (5 first order descriptors, 40 GLCM features, and 12 GLRLM features) to each rotator cuff region of interest....

متن کاملTexture Analysis of Liver Tumor from Abdominal Computed Tomography in Computer Aided Diagnostic System
This paper proposes an automatic computer aided diagnostic system (CAD) for detection of liver diseases like hepatoma and hemangioma from Abdominal Computed tomography (CT) images. Liver and Lesion is segmented using gray level methods and clustering. Histogram analyzer is used to fix the threshold and morphological operation is used for post processing. Rules are applied to remove the obstacle...
متن کاملApplication of Texture Analysis Method for Classification of Benign and Malignant Thyroid Nodules in Ultrasound Images
BACKGROUND The aim of this study was to evaluate computer aided diagnosis (CAD) system with texture analysis (TA) to improve radiologists' accuracy in identification of thyroid nodules as malignant or benign. METHODS A total of 70 cases (26 benign and 44 malignant) were analyzed in this study. We extracted up to 270 statistical texture features as a descriptor for each selected region of inte...
متن کاملDiagnostic value of ultrasound-detected calcification in thyroid nodules.
INTRODUCTION This study analyses the diagnostic value of ultrasonography (US) detection for calcification in thyroid nodules. MATERIALS AND METHODS We analysed the preoperative US findings and clinical characteristics of 577 malignant and 3434 benign thyroid patients who underwent surgery in our hospital. RESULTS The malignant rate in patients with microcalcification hyperechoic and tiny ca...
