As an alternative method to the 100 mm long ionization chamber, which is normally used to measure the CT dose index (CTDI), some studies use smaller semiconductor photodetectors to measure the single ...

In a computed tomography (CT or CAT) scan, the X-ray beam moves in a circle around the body. This allows many different views of the same organ or structure, and provides much greater detail. The ...

We live in an age where medical technology can uncover what the naked eye can’t, and CT scans are a major part of that advancement. But with growing chatter around radiation exposure and ...

Computed Tomography scans are vital for diagnosis. Recent studies indicate a potential link between CT scans and increased cancer risk. In the United States, millions undergo CT scans annually.
