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 and Storage-Phosphor Radiography" which was written by Karl Ludwig, M.D. et al. states that the case study was done with the express purpose of comparing a "large-area direct-readout flat-panel detector...
The results stated in the study were that: "ROC analysis showed A) Values of 0.820 (speed class 400), 0.780 (class 800), 0.758 (class 1600), and 0.676 (class 3200) for the flat-panel detector; 0.761 (class 400), 0.725 (class 800), and 0.662 (class 1600) for the storage-phosphor system; and 0.788 (class 400) for the conventional screen-film system. As value for the flat-panel detector at speed class 400 was significantly higher than that for all other systems (P
Once the image is procured, the radiologist sets the diagnostic. In addition, a surgical technologist assists radiographers in conducting inter-operative imaging. Finally, a radiology nurse would help provide patient care during radiological investigations or procedures by using their skills to identify and meet a patient's individual needs. In my view, a professional medical team member is essentially empathetic. Given that the healthcare sector is the only working space that concerns
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
Radiology and Ethics In the contemporary world of today, radiologists face a number of ethical challenges that are rather different as compared to the issues faced by other physicians in the healthcare field. This is due to the fact that the interaction between the physicians and patients is not like one that is in other fields. The issues that radiologists are challenged with on a daily basis include speeding up of
He proposed this technique as the solution to the problem of why some people do better than others in certain tasks, He likewise suggested cataloguing the differences in the size of the functional areas among individuals and correlating these with different talents and skills (Krotz 2001). Van Essen believed that his technique would ultimately lead to what makes people human or unique. Brain mapping charts and determines specific areas, such
Under conventional radiology, excessive exposure outputs a "black" film. In case of digital systems, good images are got from a large range of doses. With the help of digital fluoroscopy systems, it is extremely simple to get as well as delete images. There might be an inclination to get more images than what is required. In case of digital radiology, higher patient dosage implies improved image quality and therefore
Very near the beginning of World War II, Karl Dussik began exploring ultrasound technology for diagnostic purposes by "attempted to locate brain tumors and the cerebral ventricles by measuring the transmission of ultrasound beam through the skull" (Woo 7). This experiment produced disappointing results, and the development of this apparatus was not pursued further because of the elaborate set-up, and lack of clear visual representations of the brain. However, at about
