Ultraääniluku

Ultraääniluku refers to the numerical representation of the loudness or intensity of an ultrasound signal. In medical ultrasound imaging, this number is crucial for interpreting the displayed image and understanding the characteristics of the tissues being examined. The value typically corresponds to the amplitude of the reflected ultrasound waves. Higher ultraääniluku values usually indicate stronger reflections, which can be caused by denser or more echogenic tissues. Conversely, lower values suggest weaker reflections, often associated with fluid-filled structures or less dense tissues.

The specific scale and units for ultraääniluku can vary depending on the ultrasound machine and its settings. Manufacturers often employ proprietary scales or decibel (dB) units to quantify these signal strengths. Adjusting parameters like gain or output power on the ultrasound device directly influences the ultraääniluku and, consequently, the brightness of the image. Sonographers meticulously adjust these settings to optimize image quality, ensuring that subtle differences in tissue echogenicity are visible for accurate diagnosis. Understanding the ultraääniluku helps in differentiating between various anatomical structures and identifying pathological conditions.
