Ultrasound is currently widely used in clinical diagnosis because of its fast and safe imaging principles. As the anatomical structures present in an ultrasound image are not as clear as CT or MRI. Physicians usually need advance clinical knowledge and experience to distinguish diseased tissues. Fast simulation of ultrasound provides a cost-effective way for the training and correlation of ultr...

We propose a method for registration of 3D fetal brain ultrasound with a reconstructed magnetic resonance fetal brain volume. This method, for the first time, allows the alignment of models of the fetal brain built from magnetic resonance images with 3D fetal brain ultrasound, opening possibilities to develop new, prior information based image analysis methods for 3D fetal neurosonography. The ...

This review article discusses the current role of ultrasound in interventional spine practice as both a diagnostic tool and as a modality for image guidance with procedures. Epidemiology of spine pain, the emergence of ultrasound, advantages and disadvantages of ultrasound in comparison to other image modalities are discussed. Recent selected published articles pertaining to the role of ultraso...

This paper uses a new ultrasound tissue model to propose an ultrasound image deconvolution algorithm for improving the quality of ultrasound images. This model incorporates random fluctuations of the tissue signal within the received ultrasound RF echo signal, which has not been considered in the existing ultrasound imaging algorithms. To deal with the tissue image formation and noise reduction...

Recent study shows that fetal chromosomal abnormalities can be detected in early ultrasonic prenatal screening by identifying the absence of fetus nasal bone. The drawbacks of current method are operator dependent, observer variability and its inefficiency. In particular, accurate nasal bone detection requires highly trained sonographers and obstetrics and gynecology specialists since the ultra...

BACKGROUND Image contrast between normal tissue and brain tumours may sometimes appear to be low in intraoperative ultrasound. Ultrasound imaging of strain is an image modality that has been recently explored for intraoperative imaging of the brain. This study aims to investigate differences in image contrast between ultrasound brightness mode (B-mode) images and ultrasound strain magnitude ima...

RATIONALE AND OBJECTIVES To assess the impact of adaptive filter postprocessing on quality of ultrasound images. METHODS Ultrasound images acquired with real-time spatial compound imaging (SonoCT imaging) were subsequently processed with an adaptive real time algorithm (XRES imaging). Conventional and XRES-processed images from abdominal, pediatric or small parts ultrasound explorations were ...

Segmentation remains a necessary step in medical imaging to obtain qualitative measurements such as the location of objects of interest as well as for quantitative measurements such as area, volume or the analysis of dynamic behavior of anatomical structures over time. Among these images, ultrasound images play a crucial role, because they can be produced at video-rate and therefore allow a dyn...
