What is the effect of motion on spatial resolution?

Motion significantly impacts spatial resolution in imaging techniques used in radiology. When there is increased motion during the imaging process, it introduces blurriness to the resulting images. This blurriness occurs because the position of tissues or structures changes while the image is being captured, which can lead to overlapping of pixels and a loss of sharpness.

In radiology, high spatial resolution is essential for accurately distinguishing between structures, and any motion—whether from patient movement, pulsation, or involuntary actions—can compromise the clarity of the images produced. Therefore, controlling or minimizing motion is critical to achieving high-quality images that allow for effective diagnosis and analysis.
