Slice

Slice (pronounced: /slaɪs/), from the Old English slīcian, is a term commonly used in the medical field, particularly in imaging and surgical procedures.

Definition

In medical imaging, a slice refers to a single two-dimensional image that is part of a larger three-dimensional image. This term is often used in the context of Computed Tomography (CT) scans, Magnetic Resonance Imaging (MRI), and other imaging techniques where a three-dimensional image of a body part or organ is constructed from a series of two-dimensional images or 'slices'.

In surgical procedures, a slice refers to a thin, flat piece cut from a larger structure, such as a tissue or organ. This term is often used in the context of biopsies, where a small slice of tissue is removed for examination under a microscope.
