The beginning of fluoroscopy can be taken way back in the 90s when there wasn’t much technology. This was all discovered by Rontgen‚ who noticed a fluorescing screen during the exposure to what was later called x-ray. Back then many people where wrong after coming up with conclusions that fluoroscopy would completely replace x-ray after knowing that in fluoroscopy there was movement available in the process. In fluoroscopy‚ a machine is used. One that can use either a continuous beam or it can do

Nicolle Morales Radiology Faculty October 14‚ 2013 Radiology Observation I have always been interested in the health field‚ but I was somewhat undecided about which health career I liked the most. After a visit to a radiology facility to have an x-ray performed in my left shoulder‚ my interest in Radiologic Science started; I had discovered a career within the health field that I never thought about‚ a career where I could help others and do something different every day the more I learn

each of which uses different technologies and techniques. Computed tomography (CT)‚ fluoroscopy‚ and radiography ("conventional X-ray" including mammography) all use ionizing radiation to generate images of the body. Ionizing radiation is a form of radiation that has enough energy to potentially cause damage to DNA and may elevate a person’s lifetime risk of developing cancer. CT‚ radiography‚ and fluoroscopy all work on the same basic principle: an X-ray beam is passed through the body where a

The first stage is an angiogram‚ which determines if the blood vessels of the liver and leading to the liver are able to withstand the procedure. Contrast is injected into the catheter and is followed via fluoroscopy to the liver. All imaging is acquired via fluoroscopy. If the patient is able to tolerate the Y90 procedure to follow‚ vessels that the radiologist wants to block from receiving radiation are coiled off and a tracer material is injected into the patient. The patient is taken

Collimation is square or rectangular‚ and the image is not inverted (bone shows up white‚ air shows up black). Fluoroscopy: In fluoroscopy‚ the x-rays pass through the body onto a fluorescent screen‚ creating a moving x-ray image. Collimation is circular‚ and the

B. Basic Method of Protection * Time * The amount of exposure is directly proportional to the duration of exposure. * As the length of exposure time increases‚ the radiation dose received increases in direct proportion. * During fluoroscopy‚ reduced exposure time will decrease both the patient and personnel exposure. * Fluoroscopic x-ray units are equipped with 5

Fluoroscopy is very convenient and reliable method for defining land marks before implanting orthopedic devices and to verify their placement. Fluoroscopy has optimum quality and efficiency which makes it easy to use and serves as a medium of storing relevant data for future reference. Role of radiographer in operating theatre:

Dysphagia Case Study Dysphagia is a condition when a person has difficulty swallowing food or liquids. “Dysphagia may also be associated with pain. In some cases‚ swallowing may be impossible. Occasional difficulty swallowing‚ which may occur when you eat too fast or don’t chew your food well enough‚ usually isn’t cause for concern. But persistent dysphagia may indicate a serious medical condition requiring treatment”(Mayo1). Depending on what is causing the swallowing problem will determine the
