Radiographic Technique: Vertical Angle 4

What is vertical angle? Vertical angle refers to the position the Position Indicating Device (PID or cone) is along the coronal and/or sagittal planes.    A zero degree vertical angle is when the PID is positioned parallel with the axial plane.  A positive vertical angle is when the source of radiation […]


Radiographic Technique: Horizontal Angle 3

What is horizontal angle? Horizontal angle refers to the position the Position Indicating Device (PID or cone) is along the axial plane.    Horizontal angle can be increased or decreased.  A zero degree horizontal angle is when the PID is positioned parallel with the sagittal plane.  Increasing horizontal angle moves it towards […]
