Schuller's view is a lateral radiographic view of skull principally used for viewing mastoid cells. [1] The central beam of X-rays passes from one side of the head and is at an angle of 25° caudad to the radiographic plate. This angulation prevents overlap of images of the two mastoid bones. The radiograph for each mastoid is taken separately.
Lateral cephalometric radiograph is a radiograph of the head taken with the x-ray beam perpendicular to the patient's sagittal plane. Natural head position is a standardized orientation of the head that is reproducible for each individual and is used as a means of standardization during analysis of dentofacial morphology both for photos and ...

However, coronal images require the person to hyperextend their neck, which must be avoided if any possibility of neck injury exists. [8] CT scans of the head increase the risk of brain cancer, especially for children. As of 2018, it appeared that there was a risk of one excess cancer per 3,000–10,000 head CT exams in children under the age ...
An x-ray beam is angled at 45° to the orbitomeatal line. The rays pass from behind the head and are perpendicular to the radiographic plate. Another variation of the waters places the orbitomeatal line at a 37° angle to the image receptor. It is named after the American radiologist Charles Alexander Waters.
With an object-to-film interval of 15 cm and a source-to-object span of 5 feet, magnification of anatomical landmarks will be reduced in all three dimensions.When attempting to analyze a patient's anatomy through lateral and frontal cephalograms, the challenge arises due to these images being two-dimensional projections of three-dimensional ...
Caldwell's view (or Occipitofrontal view) is a radiographic view of the skull where the X-ray plate is perpendicular to the orbitomeatal line. The rays pass from behind the head and are angled at 15-20° to the radiographic plate. It is commonly used to get better view of the ethmoid and frontal sinuses. [1]
A cephalogram is an X-ray of the craniofacial area. [1] A cephalometric analysis could be used as means for measuring growth in children.. The lateral cephalogram is a profile x-ray of the skull and soft tissues and is used to assess the relation of the teeth in the jaws, the relation of the jaws to the skull and the relation of the soft tissues to the teeth and jaws.
