Study Guide Test 1 Flashcards
Anatomical Position
Is one in which the subject stands upright, with feet together flat on the floor, toes pointed forward, arms straight down by the sides of the body with palms facing forward, fingers extended, and thumbs pointed away from the body.
Beam direction passes straight through the patient from front to back
(AP) Anterior Position
Beam direction passes straight through the patient from the back to front
(PA) Posterior Anterior
Patient is laying in back (face up)
Supine
Patient is laying on stomach (face down)
Prone
Any angle that “is not” 0, 90, 270, or 180 degrees
Oblique angle
Beam direction that enters into the patients right, front side
(RAO) Right Anterior Oblique
Beam direction that enters into the patients right back side
(RPO) Right Posterior Oblique
Beam direction that enters into the patients left front side
(LAO) Left Anterior Oblique
Beam direction that enters into the patients left back side
(LPO) Left Posterior Oblique
The beam enters the patients from the left side
LT Lateral
Gantry is at 90 degrees if the patient is supine (face up)
Lt Lateral
Gantry is at 270 if the patient is prone (face down)
Lt Lateral
The beam enters the patient from the right side
Rt Lateral
Gantry is at 279 degrees is the patients is supine(face up)
Rt Lateral
Gantry is at 90 degrees if the patients is prone (face down)
Rt Lateral
“Related to coordinates”
Is right or left
X
“Related to coordinates”
Is superior or inferior (couch in or out)
Y
“Related to coordinates”
Is Anterior or postiokr (couch up or down)
Z
Two treatment fields share common central axes, 180 degrees apart. The second field is equal in size and mirrored in shape to the first field.
Parallel Opposed Fields (POP)
On the same side of the body
Directional term
Ipsilateral
On the opposite side of the body
Directional term
Contralateral
Near the point of origin
Directional term
Proximal
Farther away from the point of origin
Directional treatment
Distal
