X-ray digital linear tomosynthesis imaging
Aims: The purpose of this review includes the following: 1) to identify indications for volumetric X-ray digital linear tomosynthesis by using a filtered back projection (FBP) algorithm and 2) to compare X-ray digital linear tomosynthesis, X-ray digital radiography, conventional tomography, and computed tomography. Review: The methods include the following: 1) an overview of the tomosynthesis s...
متن کاملX-Ray Digital Linear Tomosynthesis Imaging of Arthoroplasty
Interest in tomosynthesis and its clinical applications has been revived by recent advances in digital X-ray detector technology. Conventional tomography technology provides planar information of an object from its projection images. In tomography, an X-ray tube and X-ray film receptor are positioned on either side of the object. The relative motion of the tube and film is predetermined based o...
متن کاملX-ray Digital Tomosynthesis Imaging for Pulmonary Nodule Detection
Lung cancer is currently the primary cause of cancer death, and its incidence continues to increase worldwide. Because of its high sensitivity, normal-dose helical computed tomography (CT) is currently considered the gold standard for lung cancer detection. Previous studies have shown that low-dose helical CT can detect early-stage lung cancer, thereby decreasing morbidity (Yankelevitz et al., ...
متن کاملDigital X-Ray Imaging
The use of X-ray image receptors that produce a digital image is becoming increasingly important. Possible benefits include improved dynamic range and detective quantum efficiency, improved detectability for objects of low intrinsic contrast, and reduced radiation dose. The image can be available quickly. The display is separated from the image capture so that processing and contrast adjustment...
متن کاملDual-Energy Subtraction X-Ray Digital Tomosynthesis: Basic Physical Evaluation
The present study was performed to determine the potential of applying dual-energy subtraction (DES) digital tomosynthesis to basic physical evaluations. Volumetric X-ray DES digital tomosysnthesis was used to obtain an image of a detectability phantom (an artificial lesion). The image quality of DES digital tomosynthesis was compared to that of DES radiography. The purpose of this study was to...
