Radiography Flashcards
What are the important setting’s
MA’s
Kv
WHAT DOES INCREASING THE KV DO
Increased exposure of the image receptor and reduces the difference between different structures
What does increasing the mas do
Increases plate exposure
How do x-rays interact with the patient
Different tissues in the body absorb different amounts of radiation
Thickness also affects how much is absorbed
What is the radio graphic process
Positioning Centring Collimation Exposure Labelling Artefacts
What does collimating do
Reduces the production of scattered radiation
How much do you need to include in a radiograph f a joint
Include 1/3 of the adjacent bones
How much do you need to include in a radiograph of a long bone
Whole of bone and adjacent joints
What could artefacts on a radiograph be due to
Technique
Incorrect exposure
Poor maintenance of equipment
What is the standard orientation of a lateral view radiograph
Cranial facing the viewers left
Dorsal aspect at the top
What. Does lateral view mean in radiography
Animal is lying on its side
What is the standard orientation to view a ventrodorsal/ dorsoventral view
Cranial aspect at top
Left side of animal on right side of image
What does ventrodorsal / dorsoventral view mean
Animal on its back or sternum
What is the standard orientation of a mediolateral / lateromedial radiograph of limb
Proximal aspect at top
Cranial aspect to left
What is the standard orientation of a craniocaudal/ caudocranial radiograph of limbs
Proximal aspect at top
No convention for whether lateral or medial should be left or right
