What is a Waters view xray?
noun. Wa·ters’ view ˈwȯt-ərz- : a radiographic image obtained by passing a beam of X-rays through the chin at an angle and used especially to obtain diagnostic information in a single X-ray image about the bony structures of the front of the head and especially the maxillary sinuses and frontal sinuses.
How do you take a Waters view?
Here we will discuss some plain radiographs that are usually used for visualizing paranasal sinuses. The first view of first plain radiograph that is commonly used rather most commonly used is waters.
Is Waters view and PNS View same?
It is an imaging technique to visualize paranasal sinuses (PNS) along with surrounding soft tissues. Waters view (also known as the occipitomental view) helps to get a better view of the maxillary sinuses by using X-ray beam angled at 45° to the orbitomeatal line.
Which sinuses are not seen in waters view?
The sphenoid sinus was excluded, as it does not create a reliable image on open-mouth Waters radiographs. Fig. 1: The frontal and ethmoidal sinuses show mucosal thickening on the coronal view.
What does waters method demonstrate?
A properly positioned radiograph of the facial bones with Waters method demonstrates equal distance between the lateral margin of the skull and the orbit on both sides. The petrous ridges are seen projecting immediately inferior to the maxillae.
What is frog leg lateral view?
The frog leg lateral view is a special radiograph of the pelvis to evaluate the hip. Some departments will perform this routinely instead of the AP pelvis view to reduce exposure and maintain high diagnostic accuracy 1.
What is Townes view of skull?
The Towne view is an angled anteroposterior radiograph of the skull and visualizes the petrous part of the pyramids, the dorsum sellae and the posterior clinoid processes, which are visible in the shadow of the foramen magnum.
What is Waters view used for?
Waters’ view (also known as the occipitomental view) is a radiographic view of the skull. It is commonly used to get a better view of the maxillary sinuses. 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.
What is modified waters view?
Modified Parietoacanthial (Waters) Orbital floor (plates) are visible with this projection, which also provides a less distorted view of the entire orbital rims than a parietoacanthial (Waters Method) projection.
What is occlusal view?
Occlusal X-rays show the roof or floor of the mouth and are used to find extra teeth, teeth that have not yet broken through the gums, jaw fractures, a cleft palate, cysts, abscesses or growths. Occlusal X-rays may also be used to find a foreign object.
What is cross table lateral view?
The supine cross-table lateral view is an additional projection to demonstrate the pediatric abdomen. As radiation dose is an important consideration for pediatric imaging, the horizontal beam lateral view is not often performed; although this will vary based on the department.
What is frog leg position?
Definition. A type of rest posture in an infant that indicated a generalized reduction in muscle tone. The hips are flexed and the legs are abducted to an extent that causes the lateral thigh to rest upon the supporting surface. This posture is said to resemble the legs of a frog. [ from HPO]
Why Towne’s view is done?
The Towne view allows better frontal evaluation of the posterior fossa region than a standard nonangled frontal skull view. The lambdoid suture is better evaluated than on nonangled views.
What is Townes view used for?
This projection is used to evaluate for medial and lateral displacements of skull fractures, in addition to neoplastic changes and Paget disease.
What is a lateral view?
Definition: lateral view. lateral view (lat-er-al) A visual perspective from the side.
What are the three types of dental images?
There are three types of diagnostic radiographs taken in today’s dental offices — periapical (also known as intraoral or wall-mounted), panoramic, and cephalometric. Periapical radiographs are probably the most familiar, with images of a few teeth at a time captured on small film cards inserted in the mouth.
What are the 5 tooth surfaces?
The crown of each tooth has 5 surfaces, as follows:
- Buccal (facing the cheek or lip)
- Lingual (facing the tongue)
- Mesial (between the teeth)
- Distal (between the teeth)
- Chewing (occlusal for molars and premolars, incisal for incisors and canines)

What is frog lateral view?
What is frog leg xray?
The frog-leg lateral radiograph provides accurate visualization of the femoral head-neck offset in patients being evaluated for femoroacetabular impingement. Level of Evidence: Level II, diagnostic study.
What is Forum and Magnum?
Structure and Function
The foramen magnum functions as a passage of the central nervous system through the skull connecting the brain with the spinal cord. On either side of the foramen magnum is an occipital condyle. These condyles form joints with the first cervical vertebra.
What is the Haas method?
In Haas Method the entire skull is visualized in the image with the vertex near the top and the foramen magnum and mastoid portions near the bottom. Collimation borders are visible to outer margins of skull.
What is Reverse Towne projection?
A reverse Towne’s view is simply the reverse with the face away from the emitter. The required beam entry angle for the projection would also be reversed. It’s used to observe fractures involving the condylar neck, and also when. displacement of the condyle is suspected, also good visualization of the.
What is a lateral radiographic view?
The lateral chest view examines the lungs, bony thoracic cavity, mediastinum, and great vessels.
What is AP and lateral views?
An AP oblique radiograph requires the elbow to be oriented 45 degrees in internal rotation. A lateral radiograph of the elbow requires the elbow to be flexed 90 degrees with the forearm and humerus laying flat on the table and the image receptor, ulnar side down on the receptor, and thumb/radial side up.
