3 Simple Rules to Correct Dental Radiography Positioning

NEXT Equine DR

All positioning errors involve three parameters:

  • Tube Angulation
  • Tube Position
  • Film Position

#1 IF THE IMAGE IS FORESHORTENED OR ELONGATED, ADJUST THE TUBE ANGLE.
i.e., to make the roots longer, move the tube head more laterally.

Bad Result: Not Enough Angle - Foreshortened

Bad Result: Too Much Angle - Elongated

Good Result: Good 45° Angle

#2 IF THE TARGET IS CUT OFF AT THE EDGE OF THE BEAM (CONE CUT),
SIMPLY MOVE THE BEAM OVER TOWARD THE AREA OF CONE CUT

Bad Result: Cone Cut Image

 
 

#3 IF YOU CUT THE TARGET OFF AT THE EDGE OF THE FILM, MOVE
THE FILM OVER TOWARD THE AREA YOU CUT OFF.
