What term is used for images that have equal section thicknesses and reconstruction intervals?

The term "contiguous images" refers to a set of images in which each image slice has the same thickness and the same spacing—reconstruction interval—between them. This consistency is crucial in CT imaging because it ensures that the images are uniform, facilitating better diagnostic interpretation and analysis. Contiguous imaging allows for more straightforward comparison of adjacent slices and provides continuous patient coverage without gaps, which is essential in creating a complete representation of the scanned anatomy.

In clinical practice, contiguous images enhance the accuracy of 3D reconstructions and volume rendering, as all slices contribute equally to the final imaging results. This is particularly important in areas where precise anatomical details are critical for diagnosis or treatment planning.
