COMPLETE QUESTIONS AND ANSWERS
GUARANTEED PASS GRADED A+
●● Radiographic Image.
Answer: (manipulate) images that comes up on the workstation screen
after taking an image.
●● Image Receptor (IR).
Answer: The device that receives the energy of the x-ray beam and
forms the image of the body part/ what the body parts are close to for the
images
●● Projection.
Answer: term that describes the direction or path of the central ray (CR)
of the x-ray beam
●● Central Ray (CR).
Answer: Center-most portion of the x-ray beam emitted from the x-ray
tube
●● Computed Radiography (CR).
,Answer: Cassette-based digital radiography; the digital acquisition
modality that uses storage phosphor plates to produce images
●● Oblique Position.
Answer: Radiographic position in which the body or part is rotated at an
angle
●● What are the different oblique positions?.
Answer: LAO-Left Anterior Oblique
RAO-Right Anterior Oblique
LPO-Left Posterior Oblique
RPO- Right Posterior Oblique
●● How do you know if the position is right or left?.
Answer: Which ever side is touching the imaging receptor (IR)
●● Projection Vs Position.
Answer: Projection- where the x-ray beam enters and exits from
Position- relevant to where they are places on the imaging receptor (IR)
●● AP projection.
Answer: CR enters the anterior surface and exits the posterior
, ●● PA Projection.
Answer: Central ray enters the posterior body surface and exits the
anterior body surface
●● Lateral Projection.
Answer: CR enters one side of the body, passing transversely along the
coronal plane
●● Tangential Projection.
Answer: touching a curve or surface at only one point
●● Axial Projection.
Answer: Any angle of the CR of 10 degrees or more along the long axis
of the body or body part
●● Recumbent Position.
Answer: lying down in any position
●● Supine Position.
Answer: Lying on back facing upward
●● Prone Position.
Answer: lying on abdomen, facing downward
