I would like to provide simple answer to not confuse myself with the terminology. 1what is ultrasound? Is an imaging test that uses soundwaves to show a picture. 2what kind of wave is ultrasound? longitudinal waves 3A. what property of an ultrasound wave limits resolution (that is the smallest detail that it can image)? bellow 20hz to above20000hz B. 5.0 MHz signal travels at 1540m/s through tissue. What size is the smallest structure that it can determine? _____________________________ 4.intensities of 1000-100000w/m^2 can damage individual cells. Explain what the word intensity means when used this way? _______ 5Cavitation is the creation of vapor cavities in a fluid.Explain how it happens Cavitation occurs when bubbles are pressured below the vapor pressure. 6.what is ultrasound diathermy? a deep heating method that uses high frequency acoustic vibrations 7.Explain how an ultrasound transducer generates a signal that penetrates tissue. _________ 8. How ultrasound transducer generates an image. to show an image the transducer send and receive signal a simple way is goes trough gel,matching layer,PZT, skin 9. absorption process by which ___kinetic___energy converts into ___electic___energy. This is an example of __law_of_conservation___of__energy. Explain___Law of conservation of energy is nerver made or destroyed it just changes form.
