is what determines if there is progress. Hence‚ it isn’t change‚ but progress‚ that we should be aiming for. Scientific and technological invention leads to change. But does it always lead to progress? Take for instance‚ the introduction of the ultrasound sonography. The idea in itself was path breaking‚ and this procedure was meant to assist doctors and to-be parents alike to take better care of the unborn. But in countries like India‚ it has been more of a regressive change‚ where the sonography

Did you know that bats are mammals? We know they are mammals just like us because we have analyzed them‚ and know they are warm blooded. They are the only mammal that known how to fly. Bats are nocturnal‚ which means they sleep during the day‚ and are awake at night. Bess are interesting animals. The honey bee can fly 15 miles per hour! A hive of honey bees has about 40‚000 bees in it. An attribute of the honey bee i that is has 5 eyes. A worker bee will make 1/12 of a teaspoon of honey over its

Although the use of contrast is not heavily spread in ultrasound‚ through studies it has been noted that contrast use in sonography has proven to be helpful in diagnostic imaging. CEUS which is short for contrast enhanced ultrasonography in some cases has been able to distinguish a variety of issues‚ from determining a benign or malignant lesion‚ to determining muscle injuries. According to Sconfienza‚ malignant tumors are presented with several sonographic appearances including the following “rich

Listening Vs. Hearing Listening versus Hearing by Robert M. Sherfield‚ Ph.D. http://www.netplaces.com/self-esteem/active-listening/listening-versus-hearing.htm There are weighty differences between listening and hearing. Hearing is an automatic response while listening is a voluntary action. Hearing has little to do with choice‚ while listening has everything to do with choice. Think of it in this light: Just because you have hands‚ this does not make you a painter‚ sculptor‚ or carpenter. Just

PROJECT SYNOPSIS ON MICROCONTROLLER BASED ULTRASONIC DISTANCE MEASUREMENT ABSTRACT: The microcontroller based ultrasonic distance measuring device is a device used to calculate the distance between the ultrasonic transmitter/receiver and the object whose distance is to be measured. A microcontroller is used to calculate the delay time between the transmitted signal and the received signal. ULTRASONIC WAVES: Ultra means “beyond” and sonic means “sound”. Ultrasonic

ULTRASOUND PHYSICS Name Institution a) Calculate the Acoustic impedance of subcutaneous tissue‚ muscle and bone. Assume subcutaneous tissue has a density of 1060kg/m3 (Hedrick 2003)‚ muscle has a density of 1104kg/m3 (Madjor 2008) and bone has a density of 5065kg/m3 (Hedrick 2003). Give your answer in Mrayls. Please use speed of sound as 1540m/s for tissue‚ muscle and bone In ultrasound‚ Acoustic impedance (Z) is the quantity of measurement of resistance to sound when passing through a medium

question is HIFU. HIFU stands for high-intensity focused ultrasound. According to wikipedia‚ HIFU is “similar to using a magnifying glass to focus sunlight. Focused ultrasound uses an acoustic lens to concentrate multiple intersecting beams of ultrasound on a target. Each individual beam passes through tissue with little effect but at the focal point where the beams converge‚ the energy can have useful thermal or mechanical effects.”

MEDICAL APPLICATIONS OF ULTRASONICS The applications of ultrasonics in the medical field have involved analysis and treatment. The developments in the medical field appear to be very promising. The effect of ultrasonics on tissues has been investigated. The heating and mechanical effects have been isolated. The conclusion is that there is an effect outside of the heating effect. The effects of the changes produced by high intensity sound upon the central nervous system has been investigated
