What does the detector element (DEL) pitch refer to?

The term "detector element (DEL) pitch" specifically refers to the distance measured from the center of one detector element to the center of an adjacent detector element. This distance is critical because it influences the spatial resolution of the imaging system. When the pitch is smaller, the detectors are more closely packed, which can enhance the detail and clarity of the image. This characteristic is particularly important in applications where high-resolution imaging is essential, such as in radiology.

Understanding the DEL pitch is vital when evaluating the performance of imaging systems, as it directly affects how well small structures can be visualized. A larger pitch may compromise image quality, allowing for less precise resolution in the captured images. Therefore, focusing on the distance aspect of the DEL pitch helps clarify its role in the overall effectiveness of imaging techniques.
