CT Scan (Computed Tomography): Combines multiple X-ray images to produce a comprehensive view of your body’s interior. Best for viewing bone injuries, diagnosing lung and chest problems, and detecting cancers. However, CT scans expose you to a higher dose of radiation compared to standard X-...
PURPOSE:To prevent the influence of a dark current to a radiation detector for X-ray CT combined a scintillator with photodiodes of an inverse bias state by providing sensitive areas for measuring photoelectric current and for measuring dark current on the photodiode substrates in the detector. ...
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 ...
PROBLEM TO BE SOLVED: To provide a radiation detector, a radiation detecting system and an X-ray CT system in which the number of arrays can be increased.;SOLUTION: The radiation detector has a scintillator 9 for converting incident X-rays from the surface side into light, a photodiode chip...
As new clinical indications continue to be discovered, the use of CT scan has increased rapidly over the past decade worldwidely [2,3,4,5]. Although CT scans are of great diagnostic benefits to individual patients, relatively higher radiation doses are delivered compared with other conventional ...
Jump to Sections: What Is an X-Ray? Types of X-Rays What Is a CT Scan? What Is an MRI? Similarities and Differences Schedule Your Diagnostic Imaging Test Most individuals have hadat least one medical imaging test. Three common types of imaging devices are x-rays, computed tomography (CT...
Chest CT scan allows for a more detailed view compared to a chest X-ray. For example, a chest X-ray may identify an abnormality, but a chest CT scan should be able to show the exact location and examine the nature of a formation. Chest X-ray provides a 2D image, while a chest CT...
The present invention provides a detector which suppress the crosstalk between detector cells while improving the acquisition efficiency of X-ray radiation. The detector includes a plurality of detector cells, arranged along a detection plane of X-ray, in which each detector cell has a scintillator ...
A direct-converting x-ray radiation detector is disclosed for detecting x-ray radiation, at least including a semiconductor used to detect x-ray radiation and at least one electrode attached to the semiconductor. In an embodiment, the semiconductor and the at least one electrode are electrically ...
Image detector for electromagnetic radiation (4) especially for X-radiation has a support layer (1) and photo-sensor layer (3) supported on it. Both layers are transparent and non-attenuating for X-radiation. The image detector comprises a number of interleaved support and photo-sensor layers....
