What happens to 0.5mm slices when combined?

When 0.5mm slices are combined, they effectively stack together to create thicker slices that can measure anywhere from 1mm to 10mm, depending on the number of slices combined. For example, combining two 0.5mm slices results in a single 1mm slice, while combining twenty such slices can create a 10mm slice. This ability to combine slices allows for versatility in imaging and adaptation based on the required thickness for effective diagnostic evaluations.

The key factor here is that combining these thin slices enhances the overall depth or thickness needed for certain imaging purposes without degrading the quality of the individual slices. This makes it a practical approach in computed tomography, where adjustments to slice thickness can impact resolution, contrast, and detail in the images produced.
