CORRECT
radiograph - ANSWER-image of patients anatomic parts
image receptor - ANSWER-device used to capture a radiographic image that exits the
patient; refers to both filmed-screen cassettes and digital acquisition devices
central ray - ANSWER-refers to centermost portion of the x-ray beam emitted from the
x-ray tube-the portion of the x-ray beam that has the least divergence
what do you put in the center for an xray? - ANSWER-the body part you want
cr is where the ___ is gonna leave the ____, go through the ______, and where the x-
ray beam _____ - ANSWER-cr is where the x-ray beam is gonna leave the tube, go
through the anatomy, and where the x-ray beam diverges less
where do you put the x on a radiographic image? - ANSWER-where the central ray is
radiographic procedure - ANSWER-1. bring them in room
2. position body part
3. central ray
4. radiographic protection
5. select exposure factors
6. instruct pt related to respiration
7. process of ir
anatomical position - ANSWER-arms at the sides and palms of the hands turned
forward
mid-sagittal plane - ANSWER-divides the body into equal left and right halves
coronal plane - ANSWER-divides body into front and back
mid coronal plane - ANSWER-divides the body into equal anterior and posterior parts
when do we use coronal plane? - ANSWER-for lateral images
when do we use mid-sagittal plane? - ANSWER-for supine and prone images
decubitus position - ANSWER-recumbent position with a horizontal CR
, named according to the body surface on which the patient is lying
dorsal decubitus - ANSWER-patient lying on back; central ray parallel to the floor
(horizontal), lateral projection
ventral decubitus - ANSWER-patient lying on abdomen; central ray parallel to the floor
(horizontal), lateral projection
lateral decubitus - ANSWER-lying down on the side (with x-ray beam horizontally
positioned).
when do you do both decubes? - ANSWER-for large intestine or colon
if you angle the xray tube 10 degrees up to 89.9, then we must add _____ to the
projection - ANSWER-the word axial. so not just ap projection, but ap axial projection.
pops up usually when x-raying foot
horizontal/axial/transverse - ANSWER-slices through body at right angles; intersects
with longitudinal plane
oblique plane - ANSWER-passes through the body at an angle
axial plane is not ____ to coronal or midsaggital - ANSWER-parallel
supine - ANSWER-lying on the back
prone - ANSWER-lying face down
erect - ANSWER-upright-can be standing or sitting down at 90 degrees
recumbent - ANSWER-in a reclining position, lying down, in the posture of one sleeping
or resting
dorsal recumbent - ANSWER-lying on back with legs bent and feet flat
ventral recumbent position - ANSWER-lying face down; the patient is lying down on the
belly. The face may be turned to the right or left (also called prone position).
lateral recumbent - ANSWER-lying on either the left or right side
trendelenburg position - ANSWER-lying on back with body tilted so that the head is
lower than the feet
fowler's position - ANSWER-head is higher than feet
