Which feature of a CT image represents the thickness of the slice being reconstructed?

• A. Acquisition thickness
• B. Digital matrix size
• C. Pixel intensity
• D. Reconstruction slice thickness

Answer: (D)

The feature of a CT image that represents the thickness of the slice being reconstructed is reconstruction slice thickness. This term specifically refers to the thickness of the individual slices or cross-sections of the body that are generated during the reconstruction process in a CT scan. Reconstruction slice thickness is pivotal in determining the detail and resolution of the image. Thinner slices can provide greater detail and are beneficial for examining structures in high resolution, whereas thicker slices can result in a more comprehensive view of larger areas but may obscure finer details. While acquisition thickness relates to the physical thickness of the slice that is being collected during the data acquisition phase, it is the reconstruction slice thickness that determines how data is processed and represented in the final image. Digital matrix size and pixel intensity are important components of image quality and representation but do not specifically indicate slice thickness.
