B-mode

B-mode, or brightness mode, is a common ultrasound imaging technique that creates a visual representation of the inside of the body. It works by sending high-frequency sound waves into tissues; when these waves bounce back, the machine converts the returning signals into a two-dimensional image. Brighter areas on the image indicate stronger echoes, typically from denser structures like bones or organs, while darker areas represent softer tissues. This method helps doctors visualize internal anatomy clearly, aiding in diagnosis without surgery or radiation. Its real-time capability allows for dynamic assessment of ongoing physiological processes.
