Final answer:
The best tissue differentiation of the soft tissues of the supratentorium is achieved with window settings of WW=100 and WL=30, allowing for greater contrast and detail in CT scans of the brain.
Step-by-step explanation:
The window settings that provide the best tissue differentiation of the soft tissues of the supratentorium are window width (WW) of 100 and window level (WL) of 30. These settings are known to be suitable for visualizing brain tissue in computed tomography (CT) scans, providing adequate contrast and detail for distinguishing different types of soft tissue. The narrower window width allows for a greater level of detail by increasing contrast between tissues of slightly different densities, which is essential for identifying subtle differences in the soft tissues of the brain.
