Bmodeultraääntä
Bmodeultraääntä, often referred to as B-mode ultrasound, is a diagnostic imaging technique that utilizes sound waves to create two-dimensional images of internal body structures. This method is a fundamental component of medical ultrasonography. In B-mode, the brightness of each dot on the display corresponds to the intensity or amplitude of the returning ultrasound signal, which is determined by the acoustic properties of the tissue it encounters. Denser tissues or those with significant differences in acoustic impedance reflect more sound waves, appearing brighter on the screen. Conversely, fluid-filled structures or areas with minimal reflection appear darker.
The process involves a transducer, a handheld device that emits and receives ultrasound waves. As the transducer
