(Computed Radiography Digital Solutions)
The advantages of the system can be numerous. One of them is better image quality, wherein better trabecular details would be seen; another advantage is that there is absolutely no need for retakes. This would save time and money, as well as avoid additional radiation for the patient. There will also be no loss of films, because there is no danger of these images being misplaced or lost, unlike as in the case of conventional x-rays. It is also possible to obtain multiple images with one single exposure, and the images can be manipulated according to the need of the attending physician/s. In addition, it is also possible to obtain multiple images on one film, and images can also be provided on medium other than film, like for example, on a CD, on paper, or they can even be viewed on a monitor. These are some of the many advantages that the technology of Computed Radiography provides. (Computed Radiography, finally an affordable technological advancement for conventional radiology?)
The 'Direct Digital Radiography' System provides options for the transition to digital technology. This system offers the highest quality images that are available...
Developed only in recent years, the system can be used across a large number of potential applications. The advantages of the system are that it consists of two types of detectors, one direct and the other, indirect. In the setup for its imaging, indirect sensors convert x-rays into light, and then convert that into electronic signals. The images depend on both signal profiles as well as on image resolution. The system relies on a scintillation method, wherein x-ray energy may be converted into light, and this light can then be converted into electronic signals by thin-film diodes. In the direct DR method, there is a flat panel detector in its setup, and this consists of an amorphous selenium semi-conductor x-ray absorber coating, over a thin film transistor array, made up of amorphous silicon. (Go directly from capture)
The x-ray photons that are obtained will be directly converted into electronic signals, and the advantage is that it eliminates the need for additional steps in order to capture and convert incident x-ray energy, as in other traditional methods. The innate advantage of the Direct Digital Radiography system is that the exam time would be reduced; the quality of care
It uses a great deal of expensive and cutting-edge technology, and none of this is cheap. While DR can do a great deal for a hospital radiology department, that department also must have the funds available to support what needs to be purchased and accomplished where DR is concerned if the department chooses to use this technology. Image Quality Image quality, other than cost, is quite probably the largest issue that
(Ibid) Summary & Conclusion The advantages of DR are stated to be: (1) no processing time and immediate image acquisition; (2) no imaging plates or cassettes to hassle with; and (3) excellent image quality. Disadvantages of DR include the fact that it is more expensive than CR imaging, mobile radiography necessitates a wire between computer and imaging system, the DR cannot perform corss table radiography if the imaging sensor is attached,
The conclusion according to Ludwig, et al. (2001) is that "the flat-panel detector has diagnostic performance superior to that of conventional screen-film storage-phosphor radiography for detecting shall artificial osseous lesions at clinical exposure settings. With the flat-panel detector, exposure may be reduced by a sum of 50% in order to gain satisfactory In the study entitled: "Performance of a Flat-Panel Detector in Detecting Artificial Bone Lesions: Comparison with Conventional Screen-Film
D. (http://www.cancernews.com/data/Article/210.asp). The created a need to research and develop a better method of mammography, which lead to the development of the new digital machine. What is digital mammography? Conventional film screen mammography uses low energy x-rays that pass through a compressed breast during a mammography examination. The exiting x-rays are absorbed by film (x-ray film) which is then developed into a mammography image that can be held and looked at by the
Magnetic Resonance Imaging History of MRI The Magnetic Resonance Imaging (MRI) was first tested in Budapest Hungry in 1882. Later in 1937, Professor Isidor Rabi of Columbia University assembled a Nuclear Magnetic Resonance. This tool was effective because it could absorb and emit radio waves after exposure to a strong magnetic field. Professor Carr Herman produced one-dimensional MRI imaging processor in 1952. The nuclear powered NMR was instrumental in experiments developed to
Radiology and Cyberspace The creation of 'cyberspace,' or the sharing of information through email, on the Internet and on websites, has had a profound impact on nearly every field of human endeavor. Medical science, and particularly Radiology, has been particularly affected and enhanced by new technology. Radiology, by its very nature, has always been a leader in the use of emerging technology in the medical field. Now, new technology developed during
