Final answer:
The incorrect statement is that the larger the detector element in the flat panel detector, the more the image blurs.
Step-by-step explanation:
The incorrect statement regarding detector elements is option D, which states that the larger the detector element in the flat panel detector, the more the image blurs.
The detector element size does control the spatial resolution of the system (option A), and it can be controlled by the technologist (option B) to optimize image quality.
After reading the detector element, the flat-panel detector does not automatically erase (option C), as the information is stored digitally and needs to be manually erased or overwritten.
