Which detector element (DEL) pitch size is preferred to increase spatial resolution?

Choosing a small detector element (DEL) pitch size is preferred for increasing spatial resolution in imaging systems. Spatial resolution refers to the ability of a system to distinguish between closely spaced objects or details within an image. A smaller DEL pitch results in more detector elements packed into the same area, enhancing the system's capacity to capture finer details and subtle features.

When the DEL pitch is small, each individual element can capture less area, which means they can more accurately represent the objects in the field of view. This increased density of detector elements allows for the production of images with higher resolution, leading to clearer and more precise visualization of the structures being imaged, which is crucial in medical diagnoses and other applications.

In contrast, larger DEL pitch sizes yield fewer elements over the same area, thus limiting the spatial resolution as the imaged details may be averaged out or omitted altogether. Therefore, using a small DEL pitch is instrumental in achieving the highest level of detail and clarity in imaging systems.
