What is the reflector depth in the following scenario? A pulse is emitted by a transducer and is traveling in soft tissue. The go-return time, or time of flight, of a sound pulse is 130 microseconds.
PRP(us) = imaging depth x 13 us/cm
130 us = ? x 13 us/cm
130 divide by 13 = 10 cm or
Depth(mm) = 1.54mm/us x go return time(us)/2
= 1.54 x 130/2
= 200.2/2
mm = 100.1 or 10 cm
