Bones Doing Bone Things
This term describes the direction of the central ray entering the body.
What is projection?
This position has the patient lying flat on their back.
What is supine?
The primary controlling factor of receptor exposure;it controls the quantity or number of xray photons in the xray beam.
What is mAs (milliamperage-seconds)?
This plane divides the body into equal right and left halves.
What is the midsagittal plane?
Bones that are longer than they are wide, such as the femur.
What are long bones?
This joint allows flexion and extension in one plane, such as the elbow.
What is a hinge joint?
The anatomic term meaning “toward the head.”
What is cephalad?
This position has the patient lying on their abdomen.
What is prone?
The secondary controlling factor of receptor exposure and primarily controls the quality or energy (penetration power) of the xray beam.
What is kVp (kilovoltage peak)?
This plane divides the body into anterior and posterior portions.
What is the coronal plane?
Bones that are cube-shaped and commonly found in the wrist and ankle.
What are short bones?
This joint allows rotational movement, such as the proximal radioulnar joint.
What is a pivot joint?
This term describes a radiograph taken with the patient lying down.
What is recumbent?
This position places the patient on their side.
What is lateral?
The distance of the xray source to the image receptor.
What is SID (source to image distance)?
This plane divides the body into superior and inferior portions.
What is the transverse plane?
Bones with a complex shape that do not fit other categories, such as vertebrae.
What are irregular bones?
This joint allows movement in two planes, such as the wrist.
What is a condyloid (ellipsoid) joint?
This term means the central ray enters the posterior surface and exits the anterior surface.
What is posteroanterior (PA)?
In this position, the patient's body is angled in which neither the sagittal nor the coronal body plane is perpendicular to the IR.
What is oblique?
OID stands for this.
What is object to image distance?
This plane is a longitudinal or transverse plane that is at an angle or slant.
What is oblique plane?
Bones that protect internal organs (like the brain) and provide broad surfaces for muscle attachment.
What are flat bones?
This joint allows movement in multiple planes, such as the shoulder.
What is a ball-and-socket joint?
The anatomic term meaning “near the source or beginning.”
What is proximal?
This position places the patient face with the head lower than the feet.
What is the Trendelenburg position?
These are used to prevent scatter radiation; used when a body party is thicker than 4 inches.
What are grids?
This line divides the body into equal anterior and posterior halves.
What is the midcoronal?
These bones develop within tendons, with the patella being the largest example.
What are sesamoid bones?
This joint allows gliding movements, such as between carpals.
What is a plane (gliding) joint?
