Which of the following is true regarding the Z axis in CT imaging?

In CT imaging, the Z axis refers specifically to the thickness of the slice. This is crucial because the Z axis determines how thin or thick the individual slices are that are obtained during a CT scan. The slice thickness directly influences the image resolution and detail; thinner slices can provide more information and greater detail, while thicker slices may be used to cover a larger area more quickly but may sacrifice some detail.

Understanding the importance of the Z axis in terms of slice thickness helps to appreciate how it affects the quality of the images produced and the information that radiologists can derive from them. This is vital for accurate diagnosis and effective treatment planning in medical imaging.
