What are panoramic dental X-rays used for?
Panoramic dental x-ray uses a very small dose of ionizing radiation to capture the entire mouth in one image. It is commonly performed by dentists and oral surgeons in everyday practice and may be used to plan treatment for dentures, braces, extractions and implants. This exam requires little to no special preparation.
What are the different types of dental X-rays?
There are two main types of dental X-rays: intraoral (the X-ray film is inside the mouth) and extraoral (the X-ray film is outside the mouth). Intraoral X-rays are the most common type of X-ray.
Are panoramic dental X-rays necessary?
Panoramic X-rays are an important diagnostic tool and are also valuable for planning future treatment. They are safer than other types of X-ray because less radiation enters the body.
What is orbit in radiology?
The orbits are two bony sockets at the front of the face that primarily house and protect the eyes and associated structures.
What is the function of the orbit?
The orbit, which protects, supports, and maximizes the function of the eye, is shaped like a quadrilateral pyramid, with its base in plane with the orbital rim.
What is an orbital exam?
An eye and orbit ultrasound uses high-frequency sound waves to measure and produce detailed images of your eye and eye orbit (the socket in your skull that holds your eye). This test provides a much more detailed view of the inside of your eye than a routine eye exam.
What are the two main functions of the orbit?
The orbit, which protects, supports, and maximizes the function of the eye, is shaped like a quadrilateral pyramid, with its base in plane with the orbital rim. Seven bones conjoin to form the orbital structure, as shown in the image below.
Why do I need an eye scan?
An OCT eye scan allows us to review the many layers of the eye and create a 4D picture. This means that we can detect even small changes, which might indicate the onset of an eye condition. Under the right circumstances, this means that we may be able to treat or slow the progression of eye problems.
Why would you need an eye ultrasound?
Why the Test is Performed You may need this test if you have cataracts or other eye problems. An A-scan ultrasound measures the eye to determine the right power of a lens implant before cataract surgery . A B-scan is done to look at the inside part of the eye or the space behind the eye that cannot be seen directly.
What is orbital X ray used for?
X-ray orbital radiography, whether plain X-ray or CT imaging, is commonly performed on ophthalmic patients with a history of exposure to high-velocity particles and a suspected or clinically
What is the normal finding of the orbital X ray?
The lateral view can be done by turning the x-ray tube 90° and placing the film against the affected side. Severe trauma patients will have a CT scan done instead of orbital or facial x rays. Results. Normal findings show the bones of the orbits are intact, with no fractures, tumors, or cysts that could erode the surrounding bone.
How long does an orbital X ray take?
The Chandra X-ray Observatorys operating orbit takes it 200-times higher than the Hubble Space Telescope. During each orbit of the Earth, Chandra travels one-third of the way to the Moon. The Chandra X-ray Observatorys resolving power is 0.5 arc-seconds — equal to the ability to read the letters of a stop sign at a distance of 12 miles.
What do orbital X rays involve?
Definition. Orbital x rays are a radiographic study of the area and structures containing the eyes.
