3 SPECIFIC BODY POSITIONS

Lateral Position

erect right lateral position

erect left lateral position

recumbent right lateral position

recumbent left lateral position

Obliques Position

left and right posterior oblique (LPO and RPO) position

left and right anterior oblique (RAO and LAO) position

RAO

right anterior closes to the IR

LAO

left anterior closest to the IR

RPO

right posterior closest to the IR

LPO

left posterior closest the the IR

Decubitus

right lateral decubitus position - AP or PA projection

left lateral decubitus position - AP or PA projection

dorsal decubitus position - Right and left lateral

ventral decubitus position - Right and left lateral

Left or Right lateral decubitus position - AP or PA projection

side closest to the xray table + specific body positions + projection

dorsal decubitus position - left or right lateral

portion of the body closest to the X-ray table dorsal + specific body positions + side closest to the IR

ventral decubitus position - left and right lateral

portion of the body closest to the X-ray table ventral + specific body positions + side closest to the IR

Transthoracic lateral projection

dorsiplantar and plantodorsal projection

parietoacanthial and Acanthioparietal projection

submentovertex (SMV) and verticosubmental (VSM) projection

Posteroanterior (PA) projection

CR from posterior to anterior

Anteroposterior (AP) projection

CR from anterior to posterior

AP Oblique Projection

CR enters the anterior surface and exits the posterior surface of the body or body part

rotated such as medial or lateral

PA Oblique Projection

CR enters the posterior surface and exits the anterior surface of the body or body part

Mediolateral and Lateromedial Projection

path to the CR

mediolateral - projection of ankle

lateromedial - projection of wrist

Axial Projection (AP or PA Axial)

any angle of the CR of 10° or more along the long axis of yhe body or body part

Inferosuperior or Superinferior Axial Projection

performed for the shoulder and hip

special nasal bone projection

Tangential Projection

touching a curve or surface at only ine point

AP Axial projection - lordotic position

demonstrating apices of the lungs

also called Apicolordotic Projection

Transthoracic Lateral Position - Right or Left Lateral Position

lateral position through the thorax

to indicate which shoulder closest to the IR and being examined

Dorsoplantar and Plantodorsal projection

projection of the foot

Axial Plantodorsal projection

projection of heel bone

it angled CR enters the plantar surface of the foot and exits the dorsal surface

Parietoacanthial and Acanthioparietal projection

CR enters the cranial parietal bone and exits at the acanthion (junction of nose and upper lip)

also known as PA Waters and Ap reverse Waters method, and use to visualize facial bones

Submentovertical (SMV) and Verticosubmental (VSM) Projection

used for the projection of skull and mandible
