Basic Body Positions and Related Anatomy Flashcards
-used in two ways in radiology , first as general body positions, and second as specific body positions
Position
-used to describe the manner in which the patient is places
General Body Positions
-Lying on back, facing upward
Supine or Dorsal Recumbent Position
-lying on abdomen, facing downward (head may be turned to one side)
Prone (Ventral Recumbent Position)
- an upright position, to stand or sit erect
Erect
- marked by a vertical position
Erect
- Lying down in any position (prone, supine, or on side)
Recumbent
lying face down (prone)
Ventral Recumbent
lying on back (supine)
Dorsal Recumbent
lying on side (right or left lateral)
Lateral Recumbent
- a recumbent position with the body tilted with the head lower than the feet or the feet higher than the head
Trendelenburg Position
- supine position with head tilted downward
Trendelenburg Position
- the modified version of the Trendelenburg position
Reverse Trendelenburg
- The head will be positioned up and the feet will be positioned down
Reverse Trendelenburg
- also known as the sitting position
Fowler’s Position
- mostly used for neurosurgery and shoulder surgeries
Fowler’s Position
- the patient’s head is placed at a 45-degree angle, and the hip may or may not be flexed
Fowler’s Position
- a recumbent oblique position with the patient lying on the left anterior side, with the right knee and thigh flexed and the left arm extended down behind the back.
Sim’s Position (Semiprone position)
- a recumbent (supine) position with knees and hip flexed and thighs abducted and rotated externally, supported by ankle supports.
Lithotomy Position
- used in radiography, to refer to a specific body position described by the body part closest to the IR (oblique and lateral) or by the surface on which the patient is lying (decubitus)
Specific Body Positions
- specific placement of the body part in relation to the radiographic table or IR during imaging
Specific Body Positions
- Refers to the side of, or a side view
Lateral Position
- Specific lateral positions described by the part closest to the IR or the body part from which the CR exits
Lateral Position
- the right side of the body closest to the IR in the erect/
recumbent position
Right Lateral Position
- the left side of the body closest to the IR in the erect/
recumbent position
Left Lateral Position
- an angled position in which neither the sagittal nor the coronal body plane is perpendicular or at a right angle to the IR
Oblique Position
- described by the part closest to the IR or the body part from which the CR exits
Oblique Position
-Patient is lying semi-supine on the radiographic table or standing on a vertical grid device with the right posterior aspect of the body closest to the film
Right Posterior Oblique (RPO)
-MSP at some angle between zero and 90 degrees to the cassette
Right Posterior Oblique (RPO)
-Patient is lying semi-supine on the radiographic table or standing on a vertical grid device with the left posterior aspect of the body closest to the film
-MSP at some angle between zero and 90 degrees to the cassette
Left Posterior Oblique (LPO)
- Patient is lying semi prone on the radiographic table or standing facing a vertical grid device with the right side closer to the film
- MSP at some angle between zero and 90 degrees to the cassette
Right Anterior Oblique (RAO/Semi-prone)
- Patient is lying semi prone on the radiographic table or standing facing the vertical grid device with the left side closer to the film
- MSP at some angle between zero and 90 degrees to the cassette
Left Anterior Oblique (LAO/semi prone)
- means to lie on a horizontal surface designated according to the surface on which the body is resting
- describes a patient who is lying on one of the following body surfaces: back (dorsal), front (ventral), or side (right or left lateral)
- always performed with the central ray horizontal
Decubitus (Decub) Position
- the patient lies on the side, and the x-ray beam is directed horizontally from anterior to posterior (AP) or from posterior to anterior (PA)
Right or Left lateral Decubitus Position (AP/PA Projection)
- The patient is lying on the left side facing the x-ray tube
- The CR enters the anterior side and exits the posterior side
Left Lateral Decubitus Position - AP Projection
- The patient is lying on the left side facing the image receptor
- The CR enters the posterior side and exits the anterior side
Left Lateral Decubitus Position - PA Projection
