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...
An X-ray detector and an X-ray CT apparatus that facilitate collimator plate arrangement are characterized by comprising radiation detection element arrays in which a plurality of radiation detection elements detecting a radiation generated from a radiation source are arranged in a first direction and ...
X-ray detection limit and sensitivity are important figure of merits for perovskite X-ray detectors, but literatures lack a valid mathematic expression for determining the lower limit of detection for a perovskite X-ray detector. In this work, we present a thorough analysis and new method for X...
MRIX-ray Radiation exposureNone. MRI machines do not emit ionizing radiation.Exposure to dangerous ionizing radiation. CostMRI costs range from $1,200 to $4,000 (with contrast), which is usually more expensive thanCT scansand X-rays, and most examining methods.X-Ray is relatively cheaper tha...
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...

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...
王鑫宏博士在会议中发表了名为“Phantom Study of a Protective X-ray Bone Age Assessment Instrument for Children against Scattered Radiation”的主题演讲,采用Shapiro-Wilk(S-W)、Scheirer-Ray-Hare等检验方式,对比使用美诺瓦生产的KBA-1手部X射线骨龄仪、可穿戴辐射个人防护设备(RPPE)和无防护时,这三种场景下...
X-ray computed tomography (CT) is a commercially established modality for imaging large objects like passenger luggage. CT can provide the density and the effective atomic number, which is not always sufficient to identify threats like explosives and narcotics, since they can have a similar composit...
(for details on the mechanisms of Cherenkov imaging and iCMOS camera function, see Methods). In this study, a methodology to quantify radiation dose with Cherenkov light has been examined and demonstrated using breast irradiation imaging and diagnostic imaging data from X-ray CT (computed tomography...
