Radposi Terms Flashcards
An image of a patient’s anatomic part(s), as produced by the action of x-rays on an image receptor
Radiograph
The process and procedures of producing a radiograph.
Radiography
The device that captures the radiographic image that exits the patient; refers to both film- screen cassettes and digital acquisition devices.
Image receptor
Refers to the center-most portion of the x-ray beam emitted from the x-ray tube; the portion of the x-ray beam that has the least divergence.
Central ray
Projection is a positioning term that describes the direction or path of the CR of the x-ray beam as it passes through the patient, projecting an image onto the IR.
Radiographic projection
refers to a projection of the CR from posterior to anterior.
POSTEROANTERIOR PROJECTION
projection refers to a projection of CR from anterior to posterior, the opposite of PA.
ANTEROPOSTERIOR PROJECTION
projection of the upper or lower limb that is rotated is called “oblique.” This is not a true AP projection and must also include a qualifying term that indicates which way it is rotated, such as medial or lateral rotation
Ap oblique projection
It must also include a qualifying term that indicates which way it is rotated. With a PA oblique projection, the CR enters the posterior surface and exits the anteriorsurface of the body or body part.
Pa oblique projection
A lateral projection is described by the path of the CR. Two examples are the __ of the ankle and the __ of the wrist. The medial and lateral sides are determined with the patient in the anatomic position.
Mediolateral and lateromedial projection
Lying on back, facing upward
Supine
Lying on abdomen, facing downward (head may be turned to one side).
Prone
An upright position, to stand or sit
Erect
Lying down in any position (prone, supine, or on side).
Recumbent
Lying on back (supine).
Dorsal recumbent
Lying face down (prone).
Ventral recumbent
Lying on side (right or left)
Lateral recumbent
recumbent position with the body tilted with the head lower than the feet.
Trendelenburg position
