ARDMS SPI STUDY GUIDE QUESTIONS AND ANSWERS ALREADY PASSED In soft tissue, if the frequency of a wave is increased the Propagation Speed (PS) will... Remain the Same because stiffness and density affect Propagation Speed. What is the audible range? 20-20,000Hz >20,000Hz=Ultrasound Frequency is measured in Hertz (Hz) is Cycles per Second Not affected by sonographer Increase Frequency; Decrease Depth A period is the length of time it takes for one complete wavelength to pass a fixed poin...

Logarithm - is the exponent of base 10 that equals the value of a number In decibel formulas how should values be logically arranged when comparing two numbers (V1 / V2) - If you expect a gain, place the higher number first. If you expect a loss, place the smaller number first. Explain negative decibel values - measurement just means "less than before," or in this case, "less than the reference level. It does not mean the basic unit it represents has a negative value Decibel - describes...
