Final answer:
CR spatial resolution increases as the size of the PSP pixels decreases, allowing for higher detail in medical imaging for finer diagnostic accuracy.
Step-by-step explanation:
The question addresses the concept related to Computed Radiography (CR) in medical imaging. The CR spatial frequency/resolution increases as the Pixel Size of the Photostimulable Phosphor (PSP) decreases. Spatial frequency, often measured in line pairs per millimeter (lp/mm), is an indication of how well a particular imaging system can resolve fine details in an image. A smaller pixel size allows for more pixels per given area, thus increasing the resolution and the ability to distinguish finer details.
In practical terms, if we imagine a radiographic image like a mosaic, smaller tiles (pixels) would allow for more detail to be represented in the same space, thus increasing spatial resolution. This finer granularity is particularly important when diagnosing conditions that involve small changes in tissue or bone structure. Hence, optimizing the PSP sizes in CR systems is crucial for achieving the level of detail required for accurate medical diagnoses.
