Which statement about detector elements is incorrect?

The statement that the size of the detector element can be controlled by the technologist is not accurate. In mammography systems, the size of the detector elements (often referred to as pixels or grid elements in digital imaging) is determined by the manufacturer's design and specifications of the imaging system. These specifications dictate the physical properties of the detector and cannot be altered or adjusted by the technologist during routine procedures.

In contrast, the other statements are valid. Detector elements indeed convert x-rays into electrical signals, which are then processed to create images. Their size and configuration directly influence image resolution; smaller detector elements generally lead to higher resolution images as they can capture finer details. Furthermore, the arrangement of these elements plays a significant role in image quality, as it impacts factors such as sensitivity and noise levels in the final image.
