    Tomosynthesis improves upon conventional geometric tomography in that it allows an arbitrary number of in-focus planes to be generated retrospectively from a sequence of projection radiographs that are acquired during a single motion of the x-ray tube.However, this compression causes overlapping in the breast tissue, which can sometimes obscure imaging.The C-View 2D image is the world’s first and only synthesized 2D image that is FDA approved to replace FFDM within a combined tomosynthesis screening exam.Further noted were skeletal fractures, cement fractures, fragmentation, and artifacts interfering with the diagnosis.However, unlike other x-rays, a mammogram uses a lower dose of radiation.In this paper, we describe a novel metal artifact reduction (MAR) algorithm to reduce both of these artifacts within the filtered backprojection framework.MATERIALS AND METHODS: In a prospective study, radiography and digital tomosynthesis were performed in 40 consecutive patients with total hip arthroplasty referred for suspect prosthesis loosening. (1999) X-ray coneeam tomography for metal artifacts reduction and local region reconstruction. Technical performance and utility in hip prosthesis imaging have been discussed in technical reports, but no clinical evaluation has been reported.Review: The methods include the fol-lowing: 1) an overview of the tomosynthesis system in comparison with conventional X-ray imaging tech-nology; 2) an overview of the properties of diagnostic imaging for the chest, hip joint, and temporomandibular joint when imaging overlying structures and their effect of various artificial images; and 3) a review of each system.With the recent acquisition of Perkin Elmer Imaging Components, we now offer Dexela flat panel X-ray detectors.

    Or think of the difference between a ball and a circle. Mammography usually takes two X-rays of each breast from different angles: top to bottom and side to side.Center for Medical Imaging and Physiology, Skåne University Hospital, Lund University, 221 85 Lund, Sweden Received 9 April 2013; Revised 24 July 2013; Accepted 26 July 2013Academic Editor: Sherven Sharma Copyright © 2013 Jan H. This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. The clinical utility of digital linear tomosynthesis in musculoskeletal applications has been validated in only a few reports.A Near Infrared Spectral Tomography (NIRST) system has been developed and integrated into a commercial Digital Breast Tomosynthesis (DBT) scanner to allow structural and functional imaging of breast in vivo. The source-to-image distance was modified to make the system comparable in image resolution to current two-dimensional intraoral radiography imaging systems.Fujifilm's innovative approach to dual energy subtraction further enhances diagnostic visibility with three advanced processing algorithms: Fujifilm Ac Selerate's DES delivers enhanced diagnostic detail, making it an innovative new standard of care for routine chest exams in today's changing healthcare environment, as well as offering an effective assessment and follow-up tool to help rule out the need for other, more dose-intensive and higher cost exams such as CT. Ac Selerate 3D enhanced imaging technology, digital tomosynthesis is an advanced radiography application that produces multiple tomographic slices from a single sweep of the x-ray tube.Tomosynthesis images were compared to anterior-posterior (AP) and cross-table lateral radiographs regarding demarcation and extent of demineralization and osteolysis.The purpose of this paper is to identify indications for volumetric X-ray digital linear tomosynthesis (DLT) with single- and dual-energy subtraction techniques for artificial pulmonary nodule detection and compare X-ray DLT, X-ray digital radiography, and computed tomography.Clinical benefits in medical applications include lower radiation dose to the patient without compromising image quality.Its major advantages are high frame rates, low noise, high reliability, no image lag, and high spatial resolution.However, two kinds of metal artifacts can influence diagnosis: undershooting and ripple.

    A digital image data processor collects data from the detector and a motion controller moves the source around the object. (2003) Impact of metallic dental implants on CT-based attenuation correction in a combined PET/CT scanner. RESULTS: Tomosynthesis was superior to radiography with sharper delineation of demineralization and osteolysis in the AP projection.Dynamic, portable, fast and wireless, integrated battery powered new Digital X-Ray PSA detector offers a comprehensive view of a subject, enabling practitioners to provide their clients with advanced diagnostic capabilities.Digital tomosynthesis (pronounced toh-moh-SIN-thah-sis) creates a 3-dimensional picture of the breast using X-rays. Because it is relatively new, it is available at a limited number of hospitals.Our flat panel detectors combine the best in amorphous silicon sensor panels, radiation-converting materials, low-noise analog and high-speed digital electronics, custom ASIC control and processing electronics, and compact packaging.FDR Ac Selerate uses dual energy subtraction (DES), an advanced radiographic technology that removes anatomical structures of high and low x-ray absorption, such as soft tissue or bone, which along with other underlying and/or overlying structures can obscure suspected pathology.
