Medical ultrasound interpretation requires a great deal of experience. Real-time simulation of medical ultrasound provides a cost-effective tool for training and easy access to a variety of cases and exercises. However, fully synthetic and realistic simulation of ultrasound is complex and extremely time-consuming. In this paper, we present a novel method for simulation of ultrasound images from...

OBJECTIVES Sonodynamic therapy is a physical treatment which utilizes ultrasound waves with an appropriate sensitizer such as protoporphyrin IX (PpIX). The activation of sensitizer depends on cavitation, and therefore, high intensity ultrasound is an important necessity. Beside, high intensity ultrasound can induce side effects on the healthy tissues which have surrounded tumor. The particles i...

Background & Aim: Restrictions on the use of synthetic antioxidant such as butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) are being imposed because of their carcinogecity . Experimental: In this investigation, optimization of phenolic extraction process from methanolic (80%) extract (v/v) of  Flomideschema parviflorum through response surface methodology by Fulin Ci...

A robot system for positioning an ultrasound probe has been developed [1]. Ultrasound visual servoing can be used to help ultrasound technicians position the ultrasound probe. The feasibility of visual servoing for motion in the plane of the ultrasound probe in one dimension has been addressed here. Tracking of the carotid artery for a long period of time has been demonstrated in real-time. Two...

Little is known about the efficacy of pulsed ultrasound compared with continuous ultrasound. Previous studies on the efficacy of pulsed ultrasound were not systematic and gave different results. In this study, the effects of pulse length, pulse interval, pulse length × pulse intervals, and treatment time on sonochemical activity were investigated using a simple oxidation of iodide method and a ...

Ultrasound can be used both simultaneously or as a pretreatment technique for flotation to produce higher combustible recoveries, higher heat values, and lower ash data from raw hard coals. The recent research works have indicated that modifying coal surfaces, especially physical surface cleaning with the help of the cavitation process created by power ultrasound at certain frequency and time i...
