Tomography is a diagnostic imaging method that is often referred to as basic
"sectional" or "slice" radiography. It involves taking a series of
two-dimensional images of a specific area or "slice" of the body, using a narrow
beam of radiation that passes through the body from multiple angles. These
images are then combined to create a detailed, cross-sectional view of the
internal structures, allowing for the visualization of the body without the
superimposition of structures outside the area of interest. This technique is
particularly useful for diagnosing conditions that may not be apparent on
standard X-rays.
Explanation of the other options:
1) Othopantomography: This is a type of panoramic radiography used to capture a
wide-angle view of the teeth, jaw, and other oral structures. While it does
produce an image of a "section" of the body, it is not typically referred to as
"sectional" or "slice" radiography in the same sense as tomography, as it does
not involve the same layering or cross-sectional approach.
2) Cephalogram: A cephalogram is a specific type of X-ray used in dentistry and
orthodontics to examine the soft tissues and bones of the face and head,
particularly the skull and jaw. It provides a two-dimensional, flat
representation of the head from the side view, and while it is a form of
radiography, it does not produce the layered or cross-sectional images that are
characteristic of tomography.
