Ultrasound imaging of the common carotid artery (CCA) is a non-invasive tool used in medicine to assess the severity of atherosclerosis and monitor its progression through time. It is also used in border detection and texture characterization of the atherosclerotic carotid plaque in the CCA, the identification and measurement of the intima-media thickness (IMT) and the lumen diameter that all a...

Estimation of the tissue perfusion parameters using ultrasound contrast agent can help to improve diagnosis occlusion of coronary arteries thus it can helps to prevent myocardial infarction. Precise registration of ultrasound time sequence is precondition for automatic and reliable perfusion analysis. Many image registration methods were developed, but ultrasound image registration is a still a...

Ultrasound images contain strong speckle noise and attenuation artifacts such as intensity inhomogeneity which makes the segmentation process challenging. In this paper, two segmentation algorithms have been studied and analyzed. First method is multiplicative intrinsic component optimization (MICO) algorithm which is based on the minimization of bias fields. It decomposes the ultrasound images...

Systematic transrectal ultrasound (TRUS)-guided biopsy is the standard method for a definitive diagnosis of prostate cancer. However, this biopsy approach uses two-dimensional (2D) ultrasound images to guide biopsy and can miss up to 30% of prostate cancers. We are developing a molecular image-directed, three-dimensional (3D) ultrasound image-guided biopsy system for improved detection of prost...

OBJECTIVE We describe a case series constituting the first clinical trial by intravenous (IV) team nurses using the sonic flashlight (SF) for ultrasound guidance of peripherally inserted central catheter (PICC) placement. METHODS Two IV team nurses with more than 10 years of experience with placing PICCs and 3 to 6 years of experience with ultrasound attempted to place PICCs under ultrasound ...

Medical practitioners are increasingly using digital images during disease diagnosis several state-of-the-art medical equipments are producing images of different organs, which are used during various stages of analysis. Examples of such devices include MRI, CT, ultrasound and X-Ray. In medical image processing, image denoising has become a very essential exercise all through the diagnose becau...

The real-time monitoring of non-stationary targets for image guided therapy is critical for accuracy in determining the relative locations of organs. Currently, methods for obtaining real-time monitoring using image guidance involve expensive intra-operative equipment, ionizing radiation, or are limited to surface imaging of areas accessible through videoendoscopic tools. Of all imaging modalit...

Automated motion reconstruction of the left ventricle (LV) from 3D echocardiography provides insight into myocardium architecture and function. Low image quality and artifacts make 3D ultrasound image processing a challenging problem. We introduce a LV tracking method, which combines textural and structural information to overcome the image quality limitations. Our method automatically reconstr...

Extraction and reconstruction of rectal wall structures from an ultrasound image is helpful for surgeons in rectal clinical diagnosis and 3-D reconstruction of rectal structures from ultrasound images. The primary task is to extract the boundary of the muscular layers on the rectal wall. However, due to the low SNR from ultrasound imaging and the thin muscular layer structure of the rectum, thi...
