Question

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

a. Increase the imaging depth.
b. Increase the frequency of the transducer.
c. Decrease the output power.
d. Decrease the frequency of the transducer.

Answer 1

To decrease the amount of attenuation as the ultrasound beam travels through tissues, the sonographer can decrease the frequency of the transducer.

Step-by-step explanation:

To decrease the amount of attenuation as the ultrasound beam travels through tissues, the sonographer can decrease the frequency of the transducer.

Attenuation refers to the weakening or loss of ultrasound signal as it travels through tissues. Higher frequency ultrasound waves experience more attenuation compared to lower frequency waves. Therefore, by decreasing the frequency of the transducer, the sonographer can reduce the amount of attenuation and improve the penetration of the ultrasound beam in the tissues.

By decreasing the frequency, the ultrasound beam can travel deeper into the body and provide better imaging of structures that are located at greater depths.
