positioning
A patient is lying on her back. The x-ray tube is horizontally directed with the CR entering the right side of the body. The image receptor is adjacent to the left side of the body. What is the radiographic position?
dorsal decubitus
What type of projection is created with the CR directed along or parallel to the long axis of a structure or anatomic part?
axial
When there is longitudinal angulation of the central ray with the long axis of the body, the projection will always use the term
axial
A patient is erect facing the image receptor. The left side of the body is turned 45° toward the image receptor. The CR enters the posterior aspect of the body and exits the anterior. What is this radiographic position?
LAO
A patient is erect facing the wall bucky. The left side of the body is turned 45 degrees toward the bucky. What specific position is the patient in?
LAO
a patient is erect with the back to the image receptor. the left side of the body is turned 45 degrees toward the image receptor. what is the position
LPO
a patient is recumbent facing the image receptor. the right side of the body is turned 15 degrees toward the image receptor. what is this position?
RAO
A patient is lying on her back facing the x-ray tube. The right side of her body is turned 20° toward the image receptor. What is this radiographic position?
RPO
a patient is lying facing upward with the posterior surface of the body against the image receptor. the right side of the body is turned 45 degrees toward the IR. the x-ray tube is directed vertically and enters the anterior surface of the body. what position
RPO
The patient is lying on her right side on a cart. The anterior surface of the patient is against the image receptor. A horizontal central ray enters the posterior surface and exits the anterior surface of the body. What specific projection/position has been performed?
Right lateral decubitus
A patient is erect with the left side of his chest placed against the image receptor. The central ray enters the right side of the upper chest and exits the left. Which specific position has been performed?
Transthoracic lateral
"Oblique" positions are always named according to the side of the patient that is:
closest to the IR
the patient is lying on their back. the x-ray beam is directed horizontally and enters the right side and exits the left side of the body. an image receptor is placed against the left side of the patient. what position is being performed
dorsal decubitus
A patient sitting on the table with their knee bent and foot flat on the table; the central ray is angled and enters the top of the foot and exits the bottom of the foot. What projection is this?
dorsoplantar
A patient is erect with the left side directly against the image receptor. The central ray (CR) enters the right side of the body. What is this radiographic position?
left lateral
a patient on a cart is lying on the left side. the x-ray beam is directed horizontally and enters the posterior surface and exits the anterior aspect of the body. the image receptor is against the anterior surface. which position is being performed
left lateral decubitus
A patient is erect facing the x-ray tube and leaning the shoulders backward 20° to 30° toward the IR. The central ray is perpendicular to the IR. What specific position has been performed
lordotic
a projection going through the medial side of the knee to the lateral side
mediolateral
A patient is lying on their back. The x-ray beam is placed horizontally and enters the left side of the body. What specific position is the patient in
right dorsal decubitus
A patient standing at the wall bucky with their right side against the bucky is in which specific position?
right lateral
the patient is erect with the right side of the body against the image receptor. the x-ray beam enters the left side and exits the right side of the body. what is the position
right lateral
A patient is laying on their right side and the x-ray beam is placed horizontally entering the anterior surface of the body.
right lateral decubitus AP projection
