What is mortise view of ankle?
What is mortise view of ankle?
The mortise view shows the entire mortise joint space between the talar dome and the medial malleolus, tibial plafond and lateral malleolus (Figures 1B and 2). On the AP view, the lateral malleolus overlaps and obscures the lateral joint space (Figure 1A).
What is an axial x-ray?
axial: central ray passes through (or parallel) to the long axis of the body. in some cases, however, the central ray runs through (or parallel) to the long axis of the skeletal segment studied (for example, the axial view of the calcaneus)
What is an axial projection?
Axial projection. Radiographic projection devised to obtain direct visualization of the base of the skull. Synonym: axial view, base projection, submental vertex projection, submentovertical projection, verticosubmental view.Jul 21, 2021
What is a calcaneus X-ray?
The calcaneus axial view is part of the two view calcaneus series assessing the talocalcaneal joint and plantar aspects of the calcaneus. As technology advances, computed tomography (CT) has widely been used 1 to better visualize and characterize calcaneum fragment displacements and fracture lines.May 5, 2016
How do you do Harris axial view?
To obtain the Harris view, the C-arm is rotated such that the beam is oriented parallel to the floor. With the surgeon standing in the center of the “C,” the base of the C-arm is advanced towards the posterior of the patient until the heel is adjacent to the x-ray source. Optimal axial imaging may then be obtained.
Does ankle x-ray include the foot?
During the examination, an X-ray machine sends a beam of radiation through the foot, and an image is recorded on special X-ray film or a computer. This image shows the soft tissues and bones of the foot, which include the tarsal bones (ankle bones), metatarsal bones (front end of foot), and phalanges (toes).
What does Projection mean in radiology?
Projection refers to the way the x-ray beam, like an arrow, passes through the body when the person is in that position. Remember, that arrow can pass through and project front to back, back to front, side to side, and so forth.Aug 20, 2015
What is positioning in radiology?
Position denotes the placement of the patient's body, specifically the portion of the patient's anatomy that is in contact with the Bucky. For example, C indicates a lateral projection in a right lateral position, and D indicates a lateral projection in a left lateral position.Feb 2, 2016
What does AP and lateral views mean?
Anterior-Posterior (AP) radiographs are taken with the patient facing the x-ray tube, so that the x-ray beam enters their anterior side, and exits posteriorly. ... If the patient's left side is placed next to the film, it is called a 'left lateral'.
What is the angle for a calcaneus xray?
Bohler's angle (also sometimes referred to as the "Tuber Angle") is formed by the intersection of lines 1 and line 2 on the lateral ankle radiograph. The normal range is 20 to 40 degrees. Angles < 20 degrees is suggestive of a calcaneus fracture and/or disruption of the posterior facet.
What is a Harris view of calcaneus?
The Harris Beath projection is a specialized weightbearing foot x-ray to demonstrate the calcaneal body, middle facet of the subtalar joint, and the sustenaculum tali.Mar 29, 2021
What is a normal X ray?
- Most X-rays have a wavelength ranging from 0.01 to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (3×10 16 Hz to 3×10 19 Hz) and energies in the range 100 eV to 100 keV. X-ray wavelengths are shorter than those of UV rays and typically longer than those of gamma rays.
What are the types of X - rays?
- Panoramic X-Rays. Dentists refer to these as OPG or Ortho pantomo gram. ...
- CT or Computed Tomography. It is a type of imaging that looks at interior structures in 3-D (three dimensions). ...
- CBCT or Cone Beam Computed Tomography. CBCT is a modern-day imaging technique in dentistry. ...
- Cephalometric Projections. ...
What are X ray procedures?
- X-ray (Radiography) X-ray or radiography uses a very small dose of ionizing radiation to produce pictures of the body's internal structures. X-rays are the oldest and most frequently used form of medical imaging. They are often used to help diagnosed fractured bones, look for injury or infection and to locate foreign objects in soft tissue.
What are X ray specs?
- X-ray specs are American novelties, purported to allow users to see through or into solid objects. In reality, the spectacles merely create an optical illusion; no X-rays are involved. The current paper version is sold under the name "X-Ray Spex"; a similar product is sold under the name "X-Ray Gogs".

What is the axillary view used for in dentistry?What is the axillary view used for in dentistry?
Clinicians typically use the axillary view in evaluating subluxations and dislocations of the humeral head, generally centered on the glenoid and round in contour. This projection is also useful in evaluating osseous Bankart lesions(5).
What is the modified trauma axial view used for?What is the modified trauma axial view used for?
The modified trauma axial view is used to assess the articulations of the shoulder and the relationship of the humeral head with the glenoid. It is an optimal projection for possible scapulohumeral dislocations, glenoid fractures and Hill-Sachs lesions 1, with a higher diagnostic yield than the lateral scapular shoulder view. Patient position
What is the history of axial projection of the skull?What is the history of axial projection of the skull?
In 1912 Grashey put out first and demonstrated the description of AP axial projection of the skull or cranium. 1926, Altchul and Towne described the same position recommendation, with strong depression of the chin, the only is the central ray angulation and its direction. Altschul recommended 40° caudad CR angle and directed to foramen magnun.
