X-ray Views

To capture a perfect X-ray image a radiographer or radiology technician should know about all the techniques to do an X-ray. Patient’s Positioning, imaging techniques, exposure factors, collimation and other things impact on the X-ray image. However, to perform each and every image there is a process in this page you will find all the projections and views of x-ray. We made this page to help you that how to do an X-ray for any of the part.

Radiograph of skull:

All radiograph of skull are undertaken with reference to a series of palpable landmarks and recognized lines or planes of the skull.


  • Outer canthus of eye: The point where upper and lower eyelids meet laterally.
  • Infra orbital margin/point: The inferior rim of the orbit, with the point being located at its lowest point.
  • Nasion: The articulation between nasal and frontal bones.
  • Glabella: A bony prominence found on the frontal bone immediately superior to the nasion.
  • Vertex: The highest point if the skull in the median sagittal plane.
  • External occipital protuberance (Inion): A bony prominence found on the occipital bone usually, coincident with the median sagittal plane.
  • External auditory meatus: The opening within the ear that leads into the external auditory canal.


  • Inter-orbital (inter-pupillary) line: Join the center of the two orbits or the center of two pupils when the eyes are looking straight forward.
  • Infra-orbital line: Joints the two infra-orbital points.
  • Anthropological baseline: Passes from the infra-orbital point to the upper border of the external auditory meatus (also known as frankfurter line).
  • Orbito-meatal baseline/radiographic baseline: Extends from the outer canthus of the eye to the center of external auditory meatus. This line is aligned approx. 10° to the anthropological baseline.


  • Median sagittal plane: Divides the skull into right and left halves. The landmarks on this plane are nasion anteriorly and the occipital protuberance (inion) posteriorly.
  • Coronal planes: there are at right angles to the median sagittal plane and divides the head into anterior and posterior parts.
  • Anthropological plane: A horizontal plane containing the two anthropological baseline and infra-orbital line. It is an example of an axial plane. Axial planes are parallel with this plane.
  • Auricular plane: Perpendicular to the anthropological plane. Passes through the center of the two external auditory meatuses. It is an example of a coronal plane.
