AP projection (anteroposterior) A perpendicular central ray enters the anterior body surface and exits the posterior body surface. In a true AP projection without rotation, the CR is
perpendicular to the coronal plane and parallel to the MSP What does projection refer to? The path of the central ray. An AP projection of the foot is also called: a dorsoplantar projection PA projection (posteroanterior) A perpendicular central ray enters the posterior surface of the body and exits the anterior body surface. During an oblique projection the CR enters the body or body part from a side angle following an oblique plane. An AP oblique projection enters the anterior surface. An AP oblique projection of the upper or lower limbs must also include a qualifying term indicating which way it is rotated such as medial or lateral. During an oblique projection the CR enters the body or body part from a side angle following an oblique angle. A PA projection enters the posterior surface. A PA oblique projection of the upper or lower limbs must also include a qualifying term indicating which way it is rotated such as medial or lateral. Mediolateral and lateromedial projections A lateral projection is described by the path of the CR. A Mediolateral projection enters the medial side and exits the lateral side. A lateromedial projection enters the lateral and exits the medial. (used with limbs) An AP projection of the foot is also called: What three positions can PA projections be achieved in? Seated, prone and lateral decubitus In an axial projection, there is longitudinal angulation of the central ray with the long axis of the body OR a specific body part. The angle must be greater than ten degrees. How can an axial projection be achieved when keeping a perpendicular central ray? By angling the entire body or body part.
Lordotic position - AP axial projection Demonstrates the apices of the lungs. The long axis of the body is angled rather then the CR. Transthoracic lateral projection A unique lateral projection through the thorax used for shoulder radiography. Requires a positioning term (right or left lateral position) to indicate which shoulder is closest to the IR & is being examined. Dorsoplantar and plantodorsal projections Dorsoplantar (DP) describes the path of the CR from the dorsal surface to the plantar surface. Parietoacanthial and acanthioparietal projections With the parietoacanthial projection, the CR enters the parietal bone and exits at the acanthion (junction of the nose and
upper lip). Submentovertex (SMV) and verticosubmental (VSM) projections For submentovertex, the CR enters below the chin, or mentum, and exits at the
vertex or top of the skull. Refers to parts toward the head of the body. Refers to parts away from the head of the body. True or false: when a range of central ray angles, such as 5 to 15 degrees, is recommended for a given projection, the term “axial” is used because the angulation could exceed 10 degrees. A perpendicular CR enters one side of the body or body part, passes transversely along the coronal plane, and exits the opposite side. What terms are used with lateral projections of limbs? Lateromedial or Mediolateral. Enter the body or body part from a side angle following an oblique plane. Can be lateral, AP, or PA. True or false: All oblique projections are achieved by rotating the patient with the CR perpendicular to the IR. Describe a right posterior oblique position. It places the right posterior surface of the body closest to the IR and corresponds with the AP oblique projection. What must accompany an AP or PA oblique projection of the upper or lower limbs? A qualifying term such as medial or lateral rotation. What type of projection is created with the cr that merely skims a body part to project that part into profile and away from other body structures?AP or PA Oblique Projection
means touching a curve or surface at one point only. Describes a projection that skims a body part to project it away from other structures.
Which are the types of radiographic projection?Basic radiographic projections include anteroposterior, where the X-ray beam enters the front of the body and exits through the back; posteroanterior, where it enters the back and exits the front; lateral projections, or side views; and oblique projections where the body is positioned at a 45-degree angle relative to ...
What projection is frequently performed for the shoulder and hip where the CR enters below or inferiorly and exits above or superiorly?Inferosuperior axial projections are frequently performed for the shoulder and hip, where the CR enters below or inferior lay and exits above or superiority. Tangential means touching a curve or surface at only one point.
