  2. Radiographic anatomy - Wikipedia

    en.wikipedia.org/wiki/Radiographic_anatomy

    The x-ray film represents a two-dimensional image of a three-dimensional object due to the summary projection of different anatomical structures onto a planar surface. It requires certain skills for the correct interpretation of such images. Radiological anatomy is a necessary component of training for medical students and radiologists.

  3. Projectional radiography - Wikipedia

    en.wikipedia.org/wiki/Projectional_radiography

    Projectional radiography, also known as conventional radiography, [1] is a form of radiography and medical imaging that produces two-dimensional images by X-ray radiation.The image acquisition is generally performed by radiographers, and the images are often examined by radiologists.

  4. Resolution (structural biology) - Wikipedia

    en.wikipedia.org/wiki/Resolution_(structural...

    The details are smeared away as the resolution becomes lower. Resolution in the context of structural biology is the ability to distinguish the presence or absence of atoms or groups of atoms in a biomolecular structure. Usually, the structure originates from methods such as X-ray crystallography, electron crystallography, or cryo-electron ...

  5. Radiography - Wikipedia

    en.wikipedia.org/wiki/Radiography

    Radiography is an imaging technique using X-rays, gamma rays, or similar ionizing radiation and non-ionizing radiation to view the internal form of an object.Applications of radiography include medical ("diagnostic" radiography and "therapeutic radiography") and industrial radiography.

  6. Chest radiograph - Wikipedia

    en.wikipedia.org/wiki/Chest_radiograph

    A radiation source is positioned behind the patient at a standard distance (most often 6 feet, 1,8m), and the x-ray beam is fired toward the patient. In anteroposterior (AP) views, the positions of the x-ray source and detector are reversed: the x-ray beam enters through the anterior aspect and exits through the posterior aspect of the chest.

  7. Medical imaging - Wikipedia

    en.wikipedia.org/wiki/Medical_imaging

    The radioactive gamma rays are emitted through the body as the natural decaying process of these isotopes takes place. The emissions of the gamma rays are captured by detectors that surround the body. This essentially means that the human is now the source of the radioactivity, rather than the medical imaging devices such as X-ray or CT.

  9. Tomography - Wikipedia

    en.wikipedia.org/wiki/Tomography

    Some recent advances rely on using simultaneously integrated physical phenomena, e.g. X-rays for both CT and angiography, combined CT/MRI and combined CT/PET. Discrete tomography and Geometric tomography , on the other hand, are research areas [ citation needed ] that deal with the reconstruction of objects that are discrete (such as crystals ...
