Spi Review Edelman Ultrasound Physics |923 Questions| With Correct Answers.

Improved axial resolution is associated with {Ans: - shorter spl - shorter pulse duration - higher freq ( shorter wavelength) - fewer cycles per pulse ( less ringing) - lower numerical values}reynolds number for turbulent flow is {Ans: greater than 2,000}All waves carry _______ from one location to another. {Ans: energy}the what of a number represents the number 10s that are multiplied to create the original number {Ans: logarithm or logs (hint count the zeros ... log of 100000 is 6.. there are 6 zeros.. don't be dumb) the significance of a logarithmic scale is that as the log is increased by 1, the actual number increases tenfold.. a log increase of 2 indicates that the signal is 100 times larger}______ describes the ability to precisely position moving structures from instant to instant {Ans: temporal resolution ( temp res is excelent when a system produces many frames per second)}the beam former also adjust electrical spike voltages to reduce lobe artifacts in a process called {Ans: apodization}
