Which statement is true regarding increasing the power (dB)?

Increasing the power (measured in decibels, dB) during ultrasound imaging directly affects the intensity of the transmitted pulse. When power is increased, the amount of energy produced by the ultrasound transducer also increases, which in turn amplifies the strength of the ultrasound waves being emitted into the body. This amplification results in a more intense sound wave, which enhances the likelihood of obtaining a return echo from the structures being imaged, enabling better detection of pathology and improved overall image quality.

The other statements do not accurately represent the effects of increasing power in ultrasound imaging. For example, increasing power does not inherently decrease imaging depth; in fact, a more intense signal can help visualize deeper structures by improving the signal-to-noise ratio. Additionally, while it may have some impact on image quality, the primary change is in intensity rather than having no effect. Increasing power does not directly reduce frame rate; frame rate is more related to factors such as image depth and the number of scan lines, rather than the power level alone.
