Non-invasive cardiovascular imaging initially focused on heart structures, allowing the visualization of their motion and inferring its functional status from it. Colour-Doppler and cardiac magnetic resonance (CMR) have allowed a visual approach to intracardiac flow behaviour, as well as measuring its velocity at single selected spots. Recently, the application of new technologies to medical us...

Photoacoustic tomography, a hybrid imaging modality combining optical and ultrasound imaging, is gaining attention in the field of medical imaging. Typically, a Q-switched Nd:YAG laser is used to excite the tissue and generate photoacoustic signals. But, such photoacoustic imaging systems are difficult to translate into clinical applications owing to their high cost, bulky size often requiring ...

Sending inpatients to the medical imaging department is sometimes tantamount to discharging them from hospital for hours at a time. Consider, for example, a patient with an unexplained acute abdomen where an urgent CT scan is indicated. Patient transport, logistical delays and the procedure itself may lead to gaps in monitoring vital signs, providing intravenous fluids and administering medicat...

introduction this study is an effort to diagnose breast cancer by processing the quantitative and qualitative information obtained from medical infrared imaging. the medical infrared imaging is free from any harmful radiation and it is one of the best advantages of the proposed method. by analyzing this information, the best diagnostic parameters among the available parameters are selected and ...

Homozygous familial hypercholesterolemia (HoFH) is a rare heredity disease in which severe cardiovascular atherosclerosis develops from birth due to severe low density lipoprotein-receptor (LDL-R) defects inherited from both heterozygouscarriers of FH (HeFH) parents. This case describes a HoFH patient who underwent medical imaging examination for 4 years over a course of treatment. In addition ...

[1] We propose a dynamical model for channels incised into an erodible bed by subsurface water flow. The model is validated by the time-resolved topographic measurements of channel growth in a laboratory-scale experiment. Surface heights in the experiment are measured via a novel laser-aided imaging technique. The erosion rate in the model is composed of diffusive and advective components as we...

Over the past fifty years the processes and techniques of medical imaging have undergone a veritable explosion, calling into service increasingly sophisticated mathematical tools. Mathematics provides a language to describe the measurement processes that lead, eventually, to algorithms for turning the raw data into high-quality images. There are four principal modalities in wide application tod...

. Estimation of plaque area in Intravascular ultrasound (IVUS) images after extraction of media and plaque-lumen interfaces is an important application of computer-aided diagnosis in medical imaging. This paper presents a novel system for fully automatic and fast calculation of plaque quantity by capturing the surrounding ring called media. The system utilizes an algorithm that consists of an e...
