How does spatial resolution change with increased receive bandwidth?

In medical imaging, spatial resolution refers to the ability to distinguish between two closely spaced objects in an image. It is influenced by several factors, including the receive bandwidth. When receive bandwidth is increased, the capacity to capture a wider range of frequencies becomes available, leading to better image quality, including improved signal-to-noise ratio. This enhancement in image quality typically results in improved spatial resolution because it allows finer details to be captured and displayed more distinctly.

In this context, an increase in receive bandwidth effectively enhances the ability to delineate structures in the image, thus leading to improved spatial resolution rather than leaving it unchanged. The clarity and definition of the image are enhanced due to the availability of more data from a broader frequency range, which helps to improve the rendering of fine details.

Thus, while you indicated that the spatial resolution remains unchanged, the accurate understanding is that it actually improves with increased receive bandwidth, as the enhanced data collection capabilities directly contribute to finer detail resolution in the resulting images.
