RAD 127 RADIOGRAPHIC PROCEDURES I
ANATOMICAL AND RADIOGRAPHIC TERMINOLOGY
I.
BODY PLANES
1)
CORONAL PLANE
An imaginary plane that divides the body into ANTERIOR and
POSTERIOR segments. The MIDCORONAL PLANE divides the body
into equal anterior and posterior segments.
2)
SAGITTAL PLANE
An imaginary plane that divides the body into RIGHT and LEFT segments.
The MIDSAGITTAL PLANE divides the body into equal right and left
segments.
3)
TRANSVERSE PLANE
An imaginary plane that divides the body into SUPERIOR and INFERIOR
segments. The MIDTRANSVERSE PLANE divides the body onto equal
superior and inferior segments.
4)
AXIAL PLANE
A term that is the same as the TRANSVERSE PLANE
5)
SEMIAXIAL PLANE
An oblique imaginary plane that divides the body into SUPERIOR and
INFERIOR segments.
II. BODY SURFACES
1)
ANTERIOR (VENTRAL)
The front of the body
2)
POSTERIOR (DORSAL)
The back of the body
3)
LATERAL
That aspect of the body FARTHEST from the MIDSAGITTAL PLANE
4)
MEDIAL
That aspect of the body CLOSEST to the MIDSAGITTAL PLANE
III. RELATIVE POSITION OF ANATOMICAL STRUCTURES
1)
PROXIMAL
A part of the anatomy that is CLOSEST to the CENTER OF THE BODY
2)
DISTAL
A part of the anatomy that is FARTHEST from the CENTER OF THE
BODY
IV. POSITIONING TERMS
1)
SUPINE POSITION
The patient is lying on his/her back
2)
PRONE POSITION
The patient is lying on his/her stomach
3)
RECUMBENT POSITION
The patient is in a lying-down position
4)
RIGHT OR LEFT LATERAL RECUMBENT POSITION
The patient is lying on his/her right or left side, respectively
5)
TRENDELENBURG POSITION
The patient is in a recumbent position with the HEAD LOWER THAN THE
FEET. The patient is usually supine or prone.
6)
FOWLERS POSITION
The patient is in a recumbent position with the FEET LOWER THAN THE
HEAD. The patient is usually supine or prone.
V. RADIOGRAPHIC PROJECTIONS
1)
POSTEROANTERIOR PROJECTION (PA PROJECTION)
The patient is positioned such that the x-ray beam passes from BACK TO
FRONT to expose an image receptor (such as a film cassette).
2)
ANTEROPOSTERIOR PROJECTION (AP PROJECTION)
The patient is positioned such that the x-ray beam passes from FRONT
TO BACK to expose an image receptor (such as a film cassette)
VI. RADIOGRAPHIC POSITIONS
1)
RIGHT POSTERIOR OBLIQUE POSITION (RPO)
The patient is positioned such that the patient’s RIGHT POSTERIOR
aspect is closest to the image receptor (such as a film cassette).
2)
LEFT POSTERIOR OBLIQUE POSITION (LPO)
The patient is positioned such that the patient’s LEFT POSTERIOR aspect
is closest to the image receptor (such as a film cassette).
3)
RIGHT ANTERIOR OBLIQUE POSITION (RAO)
The patient is positioned such that the patient’s RIGHT ANTERIOR aspect
is closest to the image receptor (such as a film cassette).
4)
LEFT ANTERIOR OBLIQUE POSITION (LAO)
The patient is positioned such that the patient’s LEFT ANTERIOR aspect
is closest to the image receptor (such as a film cassette).
5)
RIGHT OR LEFT LATERAL POSITION
The patient is positioned so that the RIGHT or LEFT side, respectively, is
closest to the image receptor (such as a film cassette).
6)
VENTRAL OR DORSAL DECUBITUS POSITION
The patient is positioned PRONE or SUPINE, respectively, with the x-ray
beam entering the body HORIZONTALLY.
7)
RIGHT OR LEFT LATERAL DECUBITUS POSITION
The patient is lying on his or her RIGHT or LEFT side, respectively, with
the x-ray beam entering the body HORIZONTALLY.
VII. COMPLEX RADIOGRAPHIC POSITIONS
1)
AP MEDIAL OBLIQUE POSITION
The anatomical part is positioned so that the POSTEROMEDIAL aspect is
closest to the image receptor. This causes the x-ray beam to pass
through the part from FRONT to BACK obliquely.
2)
PA MEDIAL OBLIQUE POSITION
The anatomical part is positioned so that the ANTEROMEDIAL aspect is
closest to the image receptor. This causes the x-ray beam to pass
through the part from BACK to FRONT obliquely.
3)
AP LATERAL OBLIQUE POSITION
The anatomical part is positioned so that the POSTEROLATERAL aspect
is closest to the image receptor. This causes the x-ray beam to pass
through the part from FRONT to BACK obliquely.
4)
PA LATERAL OBLIQUE POSITION
The anatomical part is positioned so that the ANTEROLATERAL aspect is
closest to the image receptor. This causes the x-ray beam to pass
through the part from BACK to FRONT obliquely.
5)
ANY POSITION THAT INCLUDES THE TERM “AXIAL”
The position implies that the x-ray beam is directed in some direction other
than vertical or horizontal.
