Speckle Reduction for Automated Breast Ultrasound
نویسندگان
چکیده
This paper compares filtering methods for automated breast ultrasound images. The Perona-Malik diffusion filter, the diffusion stick filter and a simple median filter are evaluated as preprocessing methods for segmentation and characterization of lesions in breast ultrasound. In particular, preservation of small relevant image features, edge enhancement characteristics, and computational costs are considered.

Temperature Mapping Using Ultrasound Digital Images
Introduction: The success of hyperthermia depends on the accuracy of the temperature monitoring in the tumor and the surrounding normal tissue. In this study, the temperature changes were determined by computing the speckle displacement in the ultrasound digital images. Speckle tracking algorithm was used to compute the displacement. Materials and Methods: The experiment was perf...
متن کاملSpeckle Noise Reduction in Ultrasound Images- A Review
Ultrasound imaging is a widely used and safe medical diagnostic technique, due to its non-invasive nature, low cost and capability of forming real time imaging. Ultrasound imaging uses high-frequency sound to image internal structures by differing reflection signals produced when a beam of sound is projected into the body and bounces back at interfaces between the structures. However the useful...
متن کاملAnalysis of Contourlet Texture Feature Extraction to Classify the Benign and Malignant Tumors from Breast Ultrasound Images
Abstract— The number of Breast cancer has been increasing over the past three decades. Early detection of breast cancer is crucial for an effective treatment. Mammography is used for early detection and screening. Especially for young women, mammography procedures may not be very comfortable. Moreover, it involves ionizing radiation. Ultrasound is broadly popular medical imaging modality becaus...
متن کاملMultiresolution edge detection using enhanced fuzzy c-means clustering for ultrasound image speckle reduction.
PURPOSE Speckle suppression in ultrasound (US) images of various anatomic structures via a novel speckle noise reduction algorithm. METHODS The proposed algorithm employs an enhanced fuzzy c-means (EFCM) clustering and multiresolution wavelet analysis to distinguish edges from speckle noise in US images. The edge detection procedure involves a coarse-to-fine strategy with spatial and intersca...
متن کاملAutomated Breast Lesion Segmentation in Ultrasound Images
The main objective of this project is to segment different breast ultrasound images to find out lesion area by discarding the low contrast regions as well as the inherent speckle noise. The proposed method consists of three stages (removing noise, segmentation, classification) in order to extract the correct lesion. We used normalized cuts approach to segment ultrasound images into regions of i...
