With cone beam CT, an x-ray beam in the shape of a cone is moved around the patient to produce a large number of images, also called views. ...

An OPG is an X-ray which displays all the teeth, jaws and temperomandibular joints in a single image.

OPGs are an amazing diagnostic tool for detecting irregular teeth, cysts, tumors and infections.

A CT of the brain is a noninvasive diagnostic imaging procedure that uses special X-rays to provide detailed information about brain tissue and brain structures thus providing more data related to injuries and/or diseases of the brain. A CT of the brain may be performed to assess the brain for tumors and other lesions, injuries, intracranial bleeding, structural anomalies (e.g., hydrocephalus , infections, brain function or other conditions).A brain CT may also be used to evaluate the effects of treatment on brain tumors and to detect clots in the brain that may be responsible for strokes . Brain CT is also useful to provide guidance for brain surgery or biopsies of brain tissue. *neck* CAT scan can detect signs of disease in the throat and surrounding areas. Doctors may order a neck CAT scan to look for signs of an infection (such as an abscess), a birth defect, cysts, or tumors

CT scanning of the extremities uses a thin beam of X-ray and a rapidly moving X-ray tube to acquire data from different angles, which is used to create cross sectional images. CT scan of the extremities can provide more detailed information about bone and soft tissue structures than standard X-rays of the extremities. Therefore, this can provide more information related to injuries, infections and masses, and can be used to evaluate patients with pain, swelling, or after trauma. It can also be used to evaluate for healing after surgery and for operative complications and fracture non union.
