An image formation framework for ultrasound imaging from synthetic transducer arrays based on sparsity-driven regularization functionals using single-frequency Fourier domain data is proposed. The framework involves the use of a physics-based forward model of the ultrasound observation process, the formulation of image formation as the solution of an associated optimization problem, and the sol...

Renal cell carcinoma is an uncommon tumor in pediatric population.It is important for the clinicians to know its diagnosis as the management of renal cell carcinoma RCC is different from Wilms Tumor which is the most common tumor encountered in children .The management is surgical resection with no proven role for chemo or radiotherapy so far. Here, we present a case of seven-year-old male chil...

The role of imaging in female infertility has undergone a revolution over the past few decades .Sonography plays an integral role in the evaluation of gynecologic disease. It can determine the organ or site of abnormality and provide a diagnosis or short differential in the vast majority of patients. Both the transabdominal and transvaginal approaches are now well –established techniques for as...

Medical ultrasound imaging is a technique that has become much more prevalent than other medical imaging techniques since it is more accessible, less expensive, safe, simpler to use and produces images in the real time. However, images produced by an ultrasound imaging system, must be of sufficient quality to provide accurate clinical interpretation. The most commonly used image quality measure...

Medical ultrasound is an imaging technique that utilizes ultrasonic signals as information carriers, and has wide applications such as seeing internal body structures, finding a source of a disease, and examining pregnant women. The most commonly used ultrasonic transducer today is based on piezoelectricity. The piezoelectric transducer, however, may have a limited bandwidth and insufficient se...

Congenital diaphragmatic hernia (CDH) is a rare condition. The reported incidence of intrathoracic renal ectopia due to CDH is also rare. A right-sided thoracic kidney is much less common due to the location of the liver. Isolated intrathoracic kidney is usually asymptomatic and diagnosed incidentally on chest imaging. The authors report on a 21days old female infant with late-presenting right ...

Both MSUS and MR imaging are two suitable methods used in the investigation of immature skeleton of paediatric patients. It is important to keep in mind that these methods are complementary instead of exclusive, acting in a synergistic way when are properly combined. MSUS is a bedside method for evaluating children at all ages because of anaesthesiological support is not needed. From a paediatr...

The interaction of high-frequency ultrasound waves with the skin provides the basis for noninvasive, fast, and accessible diagnostic imaging. This tool is increasingly used in skin cancer and inflammatory conditions as well as in cosmetic dermatology. This article reviews the basic principles of skin ultrasound and its applications in the different areas of dermatology.
