One reason why focused beams with low intensities are less likely to cause bioeffects is that a focused beam is less efficient in heating a large mass of tissue to a critical temperature. correct answerTrue Typically, the sonographer can adjust the compression function of a receiver. correct answerTrue Mean frequency is calculated from weighted sum of frequencies in the power spectrum. correct answerTrue Refraction always occurs at the interface between two media when the propagation...
