Final answer:
To get deeper penetration in ultrasound imaging, increase the intensity, adjust the frequency for penetration versus resolution balance, and alter the target or transducer properties.
Step-by-step explanation:
To achieve deeper penetration in ultrasound imaging, you should increase the intensity of the ultrasound beam, which means the power per unit area needs to be higher. Changing the frequency is another method; generally, increasing the frequency provides better resolution but decreases penetration depth, so for deeper penetration, a lower frequency might be used instead.
Additionally, altering the target can also have an effect on penetration. This may relate to the choice of transducer, which is the device used to send and receive the ultrasound waves, or altering the physical properties of the target area to improve coupling and reduce reflection and scattering.
