X-RAY RADIATION DETECTOR FOR DETECTING IONIZING RADIATION, IN PARTICULAR FOR USE IN A CT SYSTEM An X-ray radiation detector is disclosed for detecting ionizing radiation, in particular for use in a CT system, with a multiplicity of detector elements. In at least one embodiment, each detector ...
and an X-ray CT system capable of obtaining a tomographic image of high resolution not having an artifact by using the radiation detector.;SOLUTION: A luminescence by the fluorescence elements (1) each having a matrix crystal made of a garnet structure containing at least Gd, Al, Ga and O...
Given concerns of radiation exposure, expert consensus advises that computed tomography (CT) should be used sparingly. However, CT can provide superior image resolution and detection of pathology. Herein, we evaluate if X-ray offers equal diagnostic accuracy compared to CT imaging in identifying CSI...
A brain CT scan equals about 2 mSv, or one year’s worth of background radiation. A low back X-ray comes in at 1.5 mSv, about eight months’ worth of natural exposure. Neck X-rays and mammograms offer lower exposures, at 0.2 mSv and 0.8 mSv respectively, but these still add up ove...
Parallel with the increased use of X-rays in preclinical research, the imaging technology has been adapted to the smaller size of the subjects with a focus on increasing the resolution within reasonable limits of delivered X-ray dose. While large animals such as sheep and pigs are frequently ...
CT scans use X-rays, which produce ionizing radiation. Research shows that this kind ofradiationmay damage your DNA and lead to cancer. But the risk is very small – your chances of developing a fatal cancer because of a CT scan are about 1 in 2,000. ...
An MRI scan, however, doesn’t work this way. It uses powerful magnets and radio waves to create the images instead of ionizing radiation. So, you are not exposed to radiation when you have an MRI scan, unlike a CT scan or x-ray. The MRI applies a magnetic field, lining up each of...
There is still uncertainty on whether ionizing radiation from CT scans can increase the risks of cancer. This study aimed to identify the association of cumulative ionizing radiation from CT scans with pertaining cancer risks in adults. Five databases we
For each examination, the volume CT dose index (CTDIvol) and dose-length product (DLP) were recorded from the dose reports generated by the scanner. The radiation effective dose (ED) was calculated as the DLP multiplied ...
