Diganostic Radiography Image Evaluation - Essay Example plate, a good quality image would need to fulfill certain physical criteria for an accurate diagnostic yield, although some parts of it are contributed to by technical soundness of the process of imaging and some are contributed to by the factors essentially related to the patient. Whatever may be the reason, a poor image quality compromises the diagnostic yield, and in some cases, a reading or a diagnosis is not possible, where the radiographic plate needs to be rejected, and re-examination is mandated (Beutel et al., 2000). In this assignment, an evaluatory report of a radiographic image will be presented with a critical discussion about the reasons for it being discarded and a re-examination being recommended. While evaluating an image, it must be borne in mind that evaluation of image is dependent on human vision as related to the examiner. Since radiographic images are essentially black and white, it is to be considered that ideal white light has flat spectrum in which all wavelengths of lights are present. In practice white light sources approximates this property. The light which has no colour or is achromatic such as in radiographic plates has only one descriptor, which is its brightness or grey value. This light has a saturation of 0% and it contains only white light. However, when the saturation varies, it becomes difficult to differentiate between two adjacent differing shades of gray which are considered to be mixtures of varying blacks and whites. Therefore, it is also to be noted that equal distances in physical intensity are not perceived as equal distances in brightness. This occurs due to the fact that intensity levels are dynamic and hence must be measured and indicated log arithmically. Intensity levels must be spaced logarithmically rather than linearly to accomplish equal steps in perceived brightness (Dougeni et al., 2007). The most important parameter of an image is its resolution. The perceived resolution is also determined by the imaging

Law and Business Ethics and Social Resonsibility Research Paper

Law and Business Ethics and Social Resonsibility - Research Paper Example The actions of insurance companies and drug producers are clearly unethical and they are even being socially irresponsible. This is because they are operating against distributive justice system. According to distributive justice system, the awards and the costs should be distributed in a fair manner. This means that those who care bare the higher cost should bare it and those who are in need of rewards should be rewarded. The insurance companies should share the cost of medical treatment with customers by decreasing their profit margins and premiums in order to share the margins. The way the drug companies and insurance companies are operating is unethical because these companies are operating against the utilitarian approach of ethics. This approach asserts that decisions that provide the highest number of awards and lowest quantity of cost to the society should be given precedence over those decisions that provide lower amount of benefits and higher amount of costs. Due to the mal practice of insurance and drug companies, the society is experiencing higher cost. KOWALEWSKI, A. J. (2011, November 3). Less Than $26 Billion? Dont Bother. - NYTimes.com.
