Match the term on the left with its correct unit. Assume that the units are for typical ultrasound values. i w|pulse duration a. g/cm hy Intensity b. W c w|particle distance c. mm cv wavelength d. Hz I period e. cm or Pa d v frequency f. Pa g v propagation speed g. m/s by power h. w/cm2 d v pulse repetition frequency . v amplitude c v spatial pulse length a v density d vpulse repetition period [ v pressureA sonographer reduces the depth of view by half during an exam. Assume that the signal was sent through soft tissue both before and after the change. Would the following increase, decrease, or remain the same? c v duty factor a. decrease c v pulse repetition frequency b. remain a v pulse repetition period C. increase by wavelength c v pulse duration by initial amplitude by period by spatial pulse length by frequency by propagation speed
