cor·o·nal sec·tion

a cross-section attained by slicing, actually or through imaging techniques, the body or any part of the body or any anatomic structure in the coronal or frontal plane, that is, in a vertical plane perpendicular to the median or sagittal plane. Given that actual sectioning in the coronal plane results in an anterior and a posterior portion, an anatomic coronal section may be a two-dimensional view of the cut surface of the posterior aspect of the anterior portion, or of the anterior aspect of the posterior portion.
Synonym(s): frontal section
