Sound waves are out of phase and resulting amplitude is increased.D. Sound waves are out of phase and resulting amplitude is decreased ENone of the above. |
| Back | A. Sound waves are in phase and resulting amplitude is increased. |
| Front | You have selected a wide-bandwidth transducer with multiple transmit frequenciesto perform a sonographic examination. Which transmit frequency should you selectfor maximum penetration?A. 3.0 MHzB. 3.5 MHzC. 4.0 MHzD. 5.0 MHzE. Penetration is not affected by frequency. |
| Back | A. 3.0 MHz |
| Front | How is bandwidth best defined?a. Decreases with shorter pulsesb. Unrelated to pulse durationc. The frequency of a pulsed. The range of frequencies in a pulse |
| Back | d. The range of frequencies in a pulse |
