When x-rays encounter different materials they are slowed or absorbed in varying amounts, creating an image. Dense material such as bone shows up as white while softer tissues show as varying shades of gray.
These 2D images are taken with an x-ray machine to evaluate internal structures.The X-ray technologist will move you into various positions while taking multiple exposures to take all necessary images required for the exam.
In this procedure, x-rays are taken in real time to view the function of internal anatomy. A contrast agent is often used to highlight structures that aren’t always visible on x-rays.
Fluoroscopy is used in the following:
During this exam, a series of x-ray images taken from different angles are combined to create images of internal structures with greater clarity than conventional x-ray.
