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...

Spatial Pulse Length is directly proportional to - ️️the Number of Cycles in the Pulse and the Wavelength (Directly Proportional means that increased SPL will increase both the number of cycles in the pulse and the wavelength if increased). Spatial pulse length is inversely proportional to - ️️Frequency (MHz) (Inversely Proportional means that increased SPL will lower frequency. This is because axial resolution is better with lower frequency) In soft tissue, if the frequency of ...

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...
