๐Ÿฉป
Add to dictionary

tomography

[tษ™หˆmษ’ษกrษ™fi ]

Definition

Context #1 | Noun

medical imaging

Tomography is a imaging technique used to create detailed images of the internal structures of an object, particularly in the medical field. This process involves taking cross-sectional images (slices) of the body which can then be compiled to form a 3D representation. It allows medical professionals to visualize areas of concern, assess damage, or diagnose conditions without invasive procedures. Common types of tomography include CT scans, MRI scans, and PET scans. The technology has revolutionized diagnostics, providing clearer images than traditional X-rays.

Synonyms

imaging, radiography, scanning.

Examples of usage

  • The doctor ordered a tomography to better understand the patient's condition.
  • CT tomography is often used in emergency situations to quickly assess injuries.
  • MRI tomography provides high-resolution images of soft tissues.

Interesting Facts

Historical Origins

  • The term originates from the Greek words 'tomos' meaning 'slice' and 'graphia' meaning 'writing' or 'drawing'.
  • The first practical use of tomography was in the early 20th century with the development of X-ray technology.
  • The advancement to computed tomography (CT) scanners in the 1970s revolutionized the way we diagnose diseases.

Science and Technology

  • CT scans use a series of X-ray images taken from different angles, which a computer processes to create cross-sectional images.
  • Magnetic resonance imaging (MRI) is another form of tomography that uses strong magnets and radio waves instead of radiation to capture images.
  • Tomography is not limited to medical uses; itโ€™s also used in fields like geology and materials science to visualize structures.

Cultural Impact

  • Tomography has changed the landscape of medicine, enabling non-invasive procedures and improved patient care.
  • TV shows and films often depict doctors using tomography to unravel mysteries of the human body in dramatic moments.
  • The availability of low-cost CT scans has become a topic of discussion regarding healthcare accessibility worldwide.

Psychology

  • Research using tomographic imaging has advanced our understanding of the brain's functions and the effects of various diseases.
  • Functional MRI (fMRI), a type of tomography, helps psychologists track brain activity related to thoughts or emotions.
  • The detailed imagery provided by tomographic techniques is crucial for developing treatments in psychological disorders.

Literature

  • In literature, the concept of 'layering' is similar to tomography, as authors unfold a story or character depth in layers.
  • Some writers use medical imagery inspired by tomography to develop metaphors about uncovering truths in their narratives.
  • Novels sometimes feature doctors who use tomography to solve mysteries, adding intrigue to the plot.

Origin of 'tomography'

The term 'tomography' comes from the Greek words 'tomos,' meaning 'slice,' and 'grapho,' meaning 'to write.' It began to gain prominence in the late 20th century as medical imaging technology advanced. The first computerized tomography (CT) scan was developed in the early 1970s by British engineer Godfrey Hounsfield and South African physicist Allan Cormack, who were later awarded the Nobel Prize in Physiology or Medicine in 1979 for their contributions. Since then, tomography has evolved significantly, incorporating various imaging modalities such as magnetic resonance imaging (MRI) and positron emission tomography (PET). The development of these techniques has transformed the ability to diagnose and treat diseases, marking a significant leap in medical science.
