Select the modification that the sonographer can make to decrease the amount of attenuation as the ultrasound beam travels through tissues.

Increase the imaging depth.
Increase the frequency of the transducer.
Decrease the output power.
Decrease the frequency of the transducer.

The correct answer is: Decrease the frequency of the transducer.

To decrease the amount of attenuation as the ultrasound beam travels through tissues, the sonographer can decrease the frequency of the transducer. Lower frequency ultrasound waves penetrate deeper into tissues and are subject to less attenuation compared to higher frequency waves. By decreasing the frequency of the transducer, the ultrasound beam will experience less absorption, scattering, and reflection as it travels through tissues, resulting in reduced attenuation and improved image quality. Increasing the imaging depth (Option A) does not directly affect the amount of attenuation experienced by the ultrasound beam. Increasing the frequency of the transducer (Option B) would actually increase the amount of attenuation as higher frequency waves are more absorbed and scattered in tissues. Decreasing the output power (Option C) may have an impact on the strength of the ultrasound beam but would not specifically target attenuation like adjusting the frequency would.
