This book was released on 2018 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: X-ray imaging is a core component of our modern medical diagnosis arsenal in combatting a broad range of disease. X-ray imaging allows medical professionals to see the internal structure and layout of the human body, and in this way allows for the visualization of unseen ailments. A current “disease of poverty” which is the target of this study is tuberculosis, a lung bacteria which is visible on x-ray imaging. X-ray imaging is a well known and used technology, yet x-ray imaging remains very expensive and unwieldy for use in less-developed regions of the world. Within the last three to four decades, the world has seen a massive explosion in consumer camera technology development, largely driven by circuit miniaturization, and this has led to cheaper and higher resolution cameras being produced. X-ray images themselves rely on a material to turn x-rays, the photons which pass through the person in medical imaging, into electrical signals which can be read by a computer. This collection of x-ray photons can be done through the coupling of a scintillating screen and a camera which images the scintillating screen to create an x-ray image. This study explores this particular method of x-ray imaging which is likely to be cheaper than existing methods of x-ray imaging, yet also likely yields images of poorer resolution and contrast distinction in x-ray images. The theoretical components necessary to setup such a system in the most efficient manner possible were analyzed, taking into consideration safety and finance constraints. The imaging capabilities of a Nikon D810 (f/1.4, 50 mm lens) and iPhone 5S (f/2.2 lens), higher and lower quality cameras respectively, were analyzed using three scintillating screens, the MCI Optonix DRZ High, Scintacor DRZ Medium, and Scintacor DRZ Ultrafine screens, to capture the x-rays produced from a 14 mA 100 kV x-ray tube. It was found that the Nikon D810 coupled with the MCI Optonix DRZ High Screen produced results similar in performance to current medical imaging, and the iPhone 5S images were too noisy to be conclusive. Further work should go into developing a more finalized and standalone product that can be tested in clinically important settings, as this study does provide the proof-of-concept framework for this to be possible.

The initial focus is on modalities that are closely related to traditional camera systems such as endoscopy and microscopy. This is followed by more complex image formation processes: magnetic resonance imaging, X-ray projection imaging, computed tomography, X-ray phase-contrast imaging, nuclear imaging, ultrasound, and optical coherence tomography.
Download or read book Large Area Digital X Ray Imaging System Phase 1 written by Dieter H. Pommerrenig and published by . This book was released on 1989 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Design trade off, and performance analysis performed during Phase 1 show conclusively, that large area, solid state digital x ray imaging panels can be produced cost competitively. Their performance level is projected to exceed the film/screen combination presently used. Also, it was concluded that the radiation dose applicable will not have detrimental effects on the gate array architectures of the electronic read out device. Large area digital x ray imaging panel will find utility in both medical diagnostic as well as industrial inspection applications. Their use will potentially replace the film currently used in these applications. The critical technologies can be summarized as follows: panel architecture, component configurations, radiation damage assessment, pixel read out rates, performance projections, and cost analysis. It was concluded that large area, solid state x ray imaging panels can be produced using present technologies.
Download or read book Design and Characterization of an 8x8 Lateral Detector Array for Digital X ray Imaging written by Christos Hristovski and published by . This book was released on 2010 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: X-ray imaging has become one of the most pervasive and effective means of diagnosis in medical clinics today. As more imaging systems transition to digital modes of capture and storage, new applications of x-ray imaging, such as tomosynthesis, become feasible. These new imaging modalities have the potential to expose patients to large amounts of radiation so the necessity to use sensitive imagers that reduce dose and increase contrast is essential. An experimental design that utilizes laterally oriented detectors and amorphous semiconductors on crystalline silicon substrates has been undertaken in this study. Emphasis on fabricating a device suitable for medical x-ray imaging is the key principle throughout the design process. This study investigates the feasibility and efficiency of a new type of x-ray imager that combines the high speed, low noise, and potential complexity of CMOS circuit design with the high responsivity, large area uniformity, and flexibility of amorphous semiconductors. Results show that the design tradeoffs made in order to create a low cost, high fill factor, and high speed imager are realistic. The device exhibits good responsivity to optical light, possesses a sufficient capacitive well, and maintains CMOS characteristics. This study demonstrates that with sufficient optimization it may be possible to design and deploy real time x-ray system on chip imagers similar to those used in optical imaging.

This book was released on 2013-06-29 with total page 525 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the proceedings of the NATO Advanced Study Institute on "Pictorial Information Systems in Medicine" held August 27-September 7, 1984 in Hotel Maritim, Braunlage/Harz, Federal Republic of Germany. The program committee of the institute consisted of KH Hohne (Director), G. T Herman, G. S. Lodwick, and D. Meyer-Ebrecht. The organization was in the hands of Klaus Assmann and Fritz Bocker In the last decade medical imaging has undergone a rapid development New imaging modalities such as Computer Tomography (CT), Digital Angiography (DSA) and Magnetic Resonance Imaging (MRI) were developed using the capabilities of modern computers. In a modern hospital these technologies produce already more then 25% of image data in digital form. This format lends itself to the design of computer assisted Information systems Integrating data acquisition, presentation, communi cation and archiving for all modalities and users within a department or even a hospital. Advantages such as rapid access to any archived Image, synoptic presentation, computer assisted image analysis to name only a few, are expected. The design of such pictorial information systems, however, often called PACS (Picture Archiving and Communication Systems) In the medical community is a non-trivial task involving know-how from many disciplines such as - Medicine (especially Radiology), - Data Base Technology, - Computer Graphics, - Man Machine Interaction, - Hardware Technology and others. Most of these disCiplines are represented by disjunct scientific communities.
Download or read book Teleradiology written by Sajeesh Kumar and published by Springer Science & Business Media. This book was released on 2008-07-25 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: Developments in teleradiology are progressing at great speed. As a consequence, there is a need for a broad overview of the field. This first-ever book on teleradiology is presented in such a way that it should make it accessible to anyone, independent of their knowledge of technology. The text is designed to be used by all professionals, including radiologists, surgeons, nurses and allied health professionals, and computer scientists. In a very short time, driven by technical developments, the field of teleradiology has become too extensive to be covered by only a small number of experts. Therefore, Teleradiology has been written with chapter contributions from a host of renowned international authorities in teleradiology (see the Contents and the Contributors). This ensures that the subject matter focusing on recent advances in teleradiology is truly up to date. Our guiding hope during this task was that as editors of multiple chapters we could still write with a single voice and keep the content coherent and simple. We hope that the clarity of this book makes up for any limitations in its comp- hensiveness.
