Which of the following Detector Element (DEL) sizes would provide the highest spatial resolution?

The correct choice is indeed the smallest Detector Element (DEL) size, which is 0.1 mm. Smaller DEL sizes are associated with higher spatial resolution because they can capture finer details of an image. Spatial resolution refers to the ability of an imaging system to distinguish small structures that are close together.

A smaller DEL size allows for more precise localization of x-ray photons that hit the detector, enabling the imaging system to differentiate between closely spaced objects. This enhancement in clarity is crucial for applications where detailed visualization is necessary, such as in radiography and mammography.

In imaging technology, the relationship between DEL size and spatial resolution is significant; thus, using a 0.1 mm DEL size maximizes the potential to discern small differences in spatial arrangement, leading to more accurate diagnostic interpretations. This understanding is fundamental in the field of imaging, as improved spatial resolution can directly translate to better patient outcomes through more accurate assessments.
