Do you use this equipment

The Gamma Knife and the computer program associated treatment planning allows doctors to locate and irradiate relatively small areas of the head (primarily in the brain) with high accuracy. This will be administered radiation dose in the (s) area (s) to deal with little effect on the surrounding tissues. The gamma knife can be used for many types of problems, for example, to treat certain cancers that appear in the brain or come to this body (primary or metastatic brain tumors), benign brain tumors (meningiomas, pituitary adenomas , acoustic neuromas), defective blood vessels (AVMs) and functional problems (trigeminal neuralgia). They are studying future uses for epilepsy and Parkinson’s disease. The Gamma Knife is not generally useful in areas measuring more than three or four centimeters.

How does this team

The gamma knife uses a technique called stereotactic radiosurgery, which uses multiple radiation beams that converge in three dimensions to focus precisely on a small amount, like a tumor, this allows radiation doses to that volume safely. Current models of gamma knife uses advanced robotics to move the patient in submillimeter increments during treatment in order to focus the radiation successfully in all areas to be treated. Treatment with gamma knife are given in a single session. Read the rest of this entry »

What is the CT scan (Computed Tomography) breast

The Computed Tomography scanning – sometimes called CAT scanning – is a noninvasive medical test that helps physicians diagnose and treat diseases.

CT scanning combines special x-ray equipment with sophisticated computers to produce multiple images or pictures of areas inside the body. Then, these cross-sectional images can be examined in a computer monitor, printed or transferred to a compact disc (CD).

CT scans of internal organs, bones, soft tissue and blood vessels provide greater clarity and reveal more detail than conventional X-ray examinations

A CT scan produces images of the face also shows the sinus cavities of the patient. The sinuses are hollow spaces filled with air located within the bones of the face and around the nasal cavity, a system of air channels connecting the nose with the back of the throat. There are four pairs of sinuses, each connected to the nasal cavity through small holes. Read the rest of this entry »
