Which of the following statements is(are) correct?                                                             

What physical concept allows us to determine the location of an interface by measuring the elapsed time between the transmitted pulsed u/s wave and the detected echo from that interface?

Which resolution relates more directly to xdcr?                                                        

The “slice thickness” of an u/s scanning plane is most closely related to the:                     

Ultrasonic image resolution through the entire field of view can be improved best by using multiple:                                                                                                             

In a pulse-echo system, the quality factor should be made as large as possible: 

Transducers should NOT be heat sterilized because:
