Article
An effective ultrasound video communication system using despeckle filtering and HEVC
(2015)The recent emergence of the high-efficiency video coding (HEVC) standard promises to deliver significant bitrate savings over current and prior video compression standards, while also supporting higher resolutions that can ...

Article
First and second order statistical texture features in carotid plaque image analysis: preliminary results from ongoing research.
(2011)Carotid plaques have been associated with ipsilateral neurological symptoms. High-resolution ultrasound can provide information not only on the degree of carotid artery stenosis but also on the characteristics of the ...

Article
High efficiency video coding for ultrasound video communication in m-health systems.
(2012)Emerging high efficiency video compression methods and wider availability of wireless network infrastructure will significantly advance existing m-health applications. For medical video communications, the emerging video ...

Article
High-resolution, low-delay, and error-resilient medical ultrasound video communication using H.264/AVC over mobile WiMAX networks
(2013)In this study, we describe an effective video communication framework for the wireless transmission of H.264/AVC medical ultrasound video over mobile WiMAX networks. Medical ultrasound video is encoded using diagnostically ...

Article
An integrated system for the segmentation of atherosclerotic carotid plaque ultrasound video
(2014)The robust border identification of atherosclerotic carotid plaque, the corresponding degree of stenosis of the common carotid artery (CCA), and also the characteristics of the arterial wall, including plaque size, ...

Article
Manual and automated media and intima thickness measurements of the common carotid artery
(2009)The intima-media thickness (IMT) of the common carotid artery (CCA) is widely used as an early indicator of the development of cardiovascular disease (CVD). It was proposed but not thoroughly investigated that the media ...

Article
Media thickness measurement of the common carotid artery.
(2007)The intima-media thickness (IMT) of the common carotid artery (CCA) is widely used as an early indicator of the development of cardiovascular disease (CVD). It was proposed but not thoroughly investigated that the media ...

Article
Multiscale amplitude-modulation frequency-modulation (AM-FM) texture analysis of ultrasound images of the intima and media layers of the carotid artery
(2011)The intima-media thickness (IMT) of the common carotid artery (CCA) is widely used as an early indicator of cardiovascular disease (CVD). Clinically, there is strong interest in identifying how the composition and texture ...

Neural networks to estimate the influence of cervix length on the prediction of spontaneous preterm delivery before 37 weeks
(2008)Neural networks were applied in an effort to predict the risk for early spontaneous preterm delivery using various demographic, clinical, and laboratory inputs. Furthermore, attention has been focused on the influence of ...

Prediction of the time period of stroke based on ultrasound image analysis of initially asymptomatic carotid plaques
(Institute of Electrical and Electronics Engineers Inc., 2015)Non-invasive ultrasound imaging of carotid plaques can provide information on the characteristics of the arterial wall including the size, morphology and texture of the atherosclerotic plaques. Several studies were carried ...

Article
Region of interest video coding for low bit-rate transmission of carotid ultrasound videos over 3G wireless networks.
(2007)Efficient medical video transmission over 3G wireless is of great importance for fast diagnosis and on site medical staff training purposes. In this paper we present a region of interest based ultrasound video compression ...

Article
Robust and efficient ultrasound video coding in noisy channels using H.264.
(2009)In this paper we define diagnostic Regions of Interest (ROIs) for carotid ultrasound medical video, which we then use as input for Flexible Macroblock Ordering (FMO) slice encoding. We extend the FMO concept by enabling ...

Article
Texture-based classification of atherosclerotic carotid plaques
(2003)There are indications that the morphology of atherosclerotic carotid plaques, obtained by high-resolution ultrasound imaging, has prognostic implications. The objective of this study was to develop a computer-aided system ...
