Which term is associated with interpolation in helical scanning?

In the context of helical scanning, slice reconstruction is a crucial concept because it refers to the process of generating cross-sectional images from the continuous data collected during the scan. Helical CT scans acquire data continuously as the patient moves through the gantry, which produces a helical path. To create the final images, interpolation techniques are used to reconstruct slices from this data.

Interpolation allows the system to estimate the values of pixels in between the actual data points collected, enabling the reconstruction of slices at very precise intervals, which is essential for achieving high-quality images. This process also helps in reducing artifacts and improving image clarity, making it possible to visualize fine details within the scanned area.

The other terms, while related to different aspects of imaging and data handling, do not specifically pertain to the interpolation process in helical scanning as directly as slice reconstruction does. Data averaging pertains more to noise reduction and may apply to other imaging techniques. Radial sampling refers to the method of collecting data in a circular pattern rather than in slice reconstruction. Sequential analysis is typically associated with assessing multiple scans or results over time rather than the immediate process of reconstructing slices from helical CT data.
