ARDMS Practice Test Prep: Diagnostic Medical Sonography Practice Exam & Study Guide

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.
