  2. Chest radiograph - Wikipedia

    en.wikipedia.org/wiki/Chest_radiograph

    A chest radiograph, chest X-ray (CXR), or chest film is a projection radiograph of the chest used to diagnose conditions affecting the chest, its contents, and nearby structures. Chest radiographs are the most common film taken in medicine.

  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. Superior thoracic aperture - Wikipedia

    en.wikipedia.org/wiki/Superior_thoracic_aperture

    The superior thoracic aperture is essentially a hole surrounded by a bony ring, through which several vital structures pass. It is bounded by: the first thoracic vertebra (T1) posteriorly; the first pair of ribs laterally, forming lateral C-shaped curves posterior to anterior; and the costal cartilage of the first rib and the superior border of the manubrium anteriorly.

  5. Heel effect - Wikipedia

    en.wikipedia.org/wiki/Heel_effect

    Graded intensity across the beam, generally a drawback, can be turned to advantage in some techniques by positioning the object or patient relative to the X-ray tube. For example, when imaging a foot , which is thicker at the ankle end than the toes, the toes should be positioned toward the anode and the ankle toward the cathode. [ 6 ]

  6. Radiography - Wikipedia

    en.wikipedia.org/wiki/Radiography

    Taking an X-ray image with early Crookes tube apparatus, late 1800s. Radiography's origins and fluoroscopy's origins can both be traced to 8 November 1895, when German physics professor Wilhelm Conrad Röntgen discovered the X-ray and noted that, while it could pass through human tissue, it could not pass through bone or metal.

  7. Thorax - Wikipedia

    en.wikipedia.org/wiki/Thorax

    An X-ray of a human chest area, with some structures labeled. The contents of the thorax include the heart and lungs (and the thymus gland); the major and minor pectoral muscles, trapezius muscles, and neck muscle; and internal structures such as the diaphragm, the esophagus, the trachea, and a part of the sternum known as the xiphoid process.

  8. Carina of trachea - Wikipedia

    en.wikipedia.org/wiki/Carina_of_trachea

    The carina occurs at the lower end of the trachea - usually at the level of the 4th to 5th thoracic vertebra. [3] [4] This is in line with the sternal angle, but the carina may raise or descend up to two vertebrae higher or lower with breathing. The carina lies to the left of the midline, and runs antero-posteriorly (front to back). [citation ...

  9. Situs solitus - Wikipedia

    en.wikipedia.org/wiki/Situs_solitus

    Situs solitus (from Latin 'usual site') is the medical term referring to the normal position of thoracic and abdominal organs. Anatomically, this means that the heart is on the left with the pulmonary atrium on the right and the systemic atrium on the left along with the cardiac apex.
