Echo times are measured by diagnostic ultrasound scanners todetermine distances to reflecting surfaces in a patient. What isthe difference in echo times (answer in milliseconds) for muscletissues that are 3.414 and 3.6266 cm beneath the surface? (Thisdifference is the minimum resolving time for the scanner to seedetails as small as 0.100 cm, or 1.00 mm. Discrimination of smallertime differences is needed to see smaller details.); Note:According to table 17.5 the speed of sound in muscle tissue is 1590m/s.
