Final answer:
Spatial resolution can be increased by using larger-size detectors, a smaller pixel size, and thinner slice thicknesses.
Step-by-step explanation:
The spatial resolution of an imaging technique can be increased by using larger-size detectors, a smaller pixel size, and thinner slice thicknesses.
Larger-size detectors can gather more light, providing more information to form a clear image. A smaller pixel size allows for more detailed and precise imaging. Thinner slice thicknesses improve the ability to distinguish objects in the image.
