X-ray photons traversing tissue may?
- pass through unaltered
- change direction with no energy loss (scatter)
- change direction losing energy (scatter with absorption)
- be stopped, depositing all energy within tissue
what is the name of a divide which changes X-ray photons into images?
what are the 3 types of x-ray image receptors?
- digital receptor (direct or indirect)
- x ray film packet

what is processing in relation to x-rays?
conversion of latent images to permanent visible images
how may radiograph processing be carried out?
- digitally (computer)

name the 3 types of intra-oral radiographs
name the 3 types of extra-oral radiographs
- lateral cephalometric radiograph (ortho)
- cone beam computer tomography (CBCT)
which does a bitewing radiograph capture?
- premolars and molars
- alveolar bone
what does a periapical radiograph capture?
full tooth including apex and tip of root
what does a panoramic radiograph capture?
what does an occlusal radiograph capture?
