radiograph
an image recorded by exposing any IR to x-radiation
-goal= maximize anatomic info on each radiograph
-Eval image to determine: acceptibility, proper safety, and image objectives met
display of radiographs
no set traditional standard
-usually oriented on display monitor in anatomical position
- protocols are set by radiologist you work for
anatomic position
standard reference posture
-standing upright
-facing forward
- arms at sides
-palms face forward
-feet flat on the floor
- head level
projections VS position
projection= path of x ray beam, named based on entrance and exit points
position= position patient is placed in , and how the part is positioned
lateral projection
beam enters on one side of the body and exits the other
- how we mark them is based on side that is cloest to IR
EX = left lateral position/ right lateral position
oblique projections
-used to visualize structures at an angle
-helps to seperate overlapping tissues and bring clarity
-name based on part of body closest to IR AND the direction of the beam.
EX= anterior obliques ( RAO/LAO)
posterior obliques ( RPO/ LPO)
AP oblique projection
require a posterior oblique postion
PA oblique projection
require an anterior oblique position
identification of radiographs
mandatory info required by law to be on all images:
-date of exam
-name or ID number
-R or L marker (digital vs lead)
-institution identity
optional items:
-pt DOB
- time of day
-ordering phys
-time markers
-pt position
