Spatial resolution in CT imaging specifically refers to the ability to define small objects distinctly. This characteristic is vital in ensuring that fine details in an image are clearly visible. High spatial resolution allows for the differentiation between objects that are close together, which is essential in clinical diagnostics where differentiating small anatomical structures can significantly impact patient assessment and treatment.

When spatial resolution is high, the resulting images possess greater detail, enabling radiologists to observe the nuances and smaller elements within the scanned area. This capability can be crucial for identifying pathologies or variations in anatomy that could otherwise be missed with lower resolution.

The other aspects mentioned, such as image clarity and contrast levels, are related but do not specifically define spatial resolution. Image clarity is more on the overall sharpness of the image, while contrast refers to the differences in intensity between various structures in the image. The range of detectable energy levels pertains to the system's ability to capture varying photon energies, contributing to image quality but not directly to spatial resolution.
