How many dimensions are represented in a B-scan image?

• A. 1
• B. 2
• C. 3
• D. 4

Answer: (B)

A B-scan image is a two-dimensional representation of data typically generated in ultrasound imaging. In this context, the two dimensions refer to the spatial axes, where one dimension represents depth (often corresponding to the distance from the transducer into the body), and the other dimension represents the lateral position (the horizontal or vertical sweep across the tissue being imaged). This allows for the visualization of structures within the body, providing a slice of the area being examined. While B-scan does incorporate additional information, such as brightness levels or grayscale to represent different tissue types, this does not add a third dimension to the spatial representation. Thus, the correct answer accurately reflects that a B-scan image captures and displays data in two dimensions.
