POSI LEC1 Flashcards
name of the exam
Radiographic view
The body part being imaged
Radiographic view
Position that the patient will be in when the exposure is made (what direction the patient is facing)
Patient position
What position the specific body part being examined will be placed in relative to the film and the x-ray beam.
Body part position
Describes the projected path of the primary x-ray beam.
Central Ray (Projection)
Where the x-ray beam enters and exits the patient.
Central Ray (Projection)
The patient is standing or lying down, facing you with the palms of the hands forward.
Anatomic Position
Enters anterior, exits posterior.
There is no angulation.
PERPENDICULAR
AP
Enters posterior, exits anterior.
There’s no angulation.
PARALLEL
PA
Enteres anterior, exits posterior.
There’s angulation in the centray ray.
PARALLEL
AXIAL
PERPENDICULAR.
There’s no angulation of the head.
TANGENTIAL
The body is always rotated 45 degrees.
There’s no angulation.
OBLIQUE
Standing or Upright
Position when the transverse plane of the body is perpendicular to the horizon
Erect
Can be lateral, supine or prone (lying down)
Position when the plane of the body is perpendicular to the horizon
Recumbent
Central ray is directed horizontally OR he x-ray beam is parallel to the horizon.
Decubitus
Central ray is directed verctically.
Recumbent
