What does B-mode imaging stand for in sonography?

B-mode imaging in sonography stands for Brightness mode imaging. This technique is fundamental in ultrasound, as it provides a two-dimensional representation of the intensity (brightness) of the reflected ultrasound waves. Each pixel in the image corresponds to an amplitude of the returning echoes, which allows clinicians to visualize and assess different structures within the body.

In B-mode imaging, varying levels of brightness represent the different tissue densities and compositions, enabling the differentiation of organs, fluids, and pathologies. This method is essential for evaluating various conditions and guiding diagnostic and therapeutic procedures in medical practice.

Understanding that B-mode stands for Brightness mode helps clarify its primary function in visualizing anatomical details through the distinct brightness levels, enhancing diagnostic capabilities in medical imaging.
