What happens to imaging quality if the output power is too low?

• A. No change in quality
• B. Image becomes brighter
• C. Image may appear weak or less defined
• D. Image gains depth

Answer: (C)

When the output power is too low, the imaging quality can indeed suffer, leading to the image appearing weak or less defined. This occurs because the ultrasound waves generated by the transducer rely on sufficient output power to penetrate the tissues and return adequate echo signals to create a clear image. If the power is insufficient, the signals may not be strong enough to differentiate between structures within the body accurately. As a result, the contrast in the image can diminish, and fine details may become lost, making it harder to visualize the anatomy. Weak signals can also lead to increased noise and artifacts in the image, further degrading overall image clarity. Therefore, maintaining an appropriate output power is crucial for achieving the best possible imaging quality in ultrasound examinations.
