In laparoscopic surgery, live video provides visualization of the exposed organ surfaces in the surgical field, but is unable to show internal structures beneath those surfaces. The laparoscopic ultrasound is often used to visualize the internal structures, but its use is limited to intermittent confirmation because of the need for an extra hand to maneuver the ultrasound probe. Other limitatio...

Abstract Cranberry pomace considered as a by-product of fruit industry contains seeds which may be processed to highly nutritive oil. Conventional extraction methods be, however, harmful natural environment, thus alternative, ultrasound-assisted method useful tool reduce environmental impact. In the following study, sonication was applied extract oil from cranberry seeds. The aim study determin...

Fetal Akinesia Deformation Sequence (FADS) is a condition characterised by decreased fetal movement (fetal akinesia), multiple joint contractures (arthrogryposis), facial anomalies, intrauterine growth restriction, pulmonary hypoplasia and other developmental abnormalities. These disorders are clinically and genetically heterogenous and its etiology remains unclear. This syndrome is rare and th...

This paper presents a comparative study between tone-burst (TB) vibro-acoustography (VA) and pulseecho ultrasound imaging on bone tissue. Vibroacoustography is an innovative technique that uses the dynamic (oscillatory) radiation force of ultrasound to remotely vibrate an object or a part of it. In response to this force, an acoustic signal is emitted which is related to the object’s mechanical...

This study evaluated the effect of pulsed low-intensity ultrasound on cell proliferation, collagen production and glycosaminoglycan deposition by human dermal fibroblasts encapsulated in alginate. Hoechst 33258 assay for cell number, hydroxyproline assay for collagen content, dimethylmethylene blue assay for glycosaminoglycan content and scanning electron microscopy were performed on the encaps...

Intraoperative ultrasound is an imaging modality frequently used to provide delineation of tissue boundaries. This paper proposes a simulation platform that enables rehearsal of patient-specific deformable ultrasound scanning in real-time, using preoperative CT as the data source. The simulation platform was implemented within the GPUaccelerated NVIDIA FleX position-based dynamics framework. Th...

Ultrasonography as an imaging modality in dentistry has been extensively explored in recent years due to several advantages that diagnostic ultrasound provides. It is a non-invasive, inexpensive, painless method and unlike X-ray, it does not cause harmful ionizing radiation. Ultrasound has a promising future as a diagnostic imaging tool in all specialties in dentistry, for both hard and soft ti...
