Summary
PACS is considered to be a high-end application of image archiving system that has been in wide use in healthcare informatics and is known best to be a modern and electronic picture archiving and communication system. To understand it in a simplified manner, this system is provided by different providers in different forms, and these are used in mainly hospital based healthcare for having an image and data acquisition system with an in-build storage system which can have on-demand display of radiological images through these display subsystems integrated by various digital networks1…

With different providers coming forward and providing these archiving and management systems, the systems across hospitals are becoming increasingly computerised with use of digital optical archives. Although these are expected to ease the image and data acquisition, there could be mechanical troubles on acquisition devices, problems with the schemes of image transmission, problems with retrieval of images, and difficulty in displaying images4. These problems have been reported to be encountered in the early phase of implementation of these systems in some hospitals, currently, the providers like Agfa and Fujifilm provide advanced systems, and these new generation systems are comparatively easier to use. They have been able to accomplish these with the use of improved hardware and software. Despite these, these systems are not free from criticisms since many users have encountered problems with digitizer on one hand and on the other, use of this new and novel system was bugged with paucity of operating processes due to lack of experience5.
The greatest advantage was perceived to be the capability to access every archived radiologic image which had been impossible with the traditional flat plate radiographic image acquisition systems due mainly to inability to integrate images with the future investigations6. It has been strongly criticised, however, that the complicated image display system would need improvement since still now, the radiologists regard the conventional image viewing system to be the best. This indicates need for further research into this area to be able to develop and implement systems which are worth wider acceptability7.
The important thing to consider is that a PACS would be involved in integration of image and data acquisition, storage, and display subsystems across various digital networks. To begin with most systems utilised DICOM standards in image communication, format, and management. Therefore when different manufacturers developed PACS components, it had to be compatible with the existing standardized DICOM services such as image storage, query, retrieval, and printing8. Essentially PACS systems would ensure a seamless dataflow across networks where compatibility with DICOM systems and necessary image conversions would be one of major requirements for these systems to be implemented. This system was dealt with differently by various PAC systems from different providers through compatibility with different applications, some of which are "diagnostic, review, analysis, and interactive teaching, as well as desktop workstations for surgical simulation, radiation therapy planning and other applications9."
Therefore, briefly, the system has been designed to work in the following fashion. The radiologists use diagnostic workstations to make a primary diagnosis. This can be ...Download file to see next pagesRead More

Against super PACs

... the functions of our elected government because the only choices the voters have for candidates will be coming from their Super PAC controlled roster of candidates. The Big Corporation money will get the candidate what he wants and in exchange, the candidate will have to remember which corporation contributed how much to his campaign and repay them in kind once any legislation affecting that corporation comes to the floor in congress. In other words, a Super PAC created public official can never be trusted to vote for and on behalf of his actual constituents. The reasons I have mentioned above are but the tip of the iceberg when it comes to the reasons as to why the voting public openly distrusts and is against the existence of the Super...

The Image of Fetish

The effect of trauma on the young was a sexual dysfunction of sorts, and Freud applied the term Fetish to describe the condition the boys would suffer in their sex life (1).
According to Freud, a young boy, experiencing a range of shame-like and fear emotions, would, upon learning the news of his mother’s “absent” penis, focus on some object while attempting to turn his gaze away from his mother, the source of his distress, and thereby avoid the news that his mother had just given him. In so doing, the object of the young boy’s attention, that object upon which the boy focused to avoid looking at his mother, would then become the object of the young boy’s subsequent sexual fetish (1). Meaning tha...

Gender and Body Image

Those body parts with which each gender was most dissatisfied were consistent with the body parts emphasized through ideal images.
It has long been recognized that our body images interact with the world and change in response especially in terms of a culturally defined set of social relations. (Sault, p. 18) Here, it is stressed that every action upon our bodies is a symbolic act that represents our social relationships which in turn are reciprocally related and grow together, with a change in one reflected by a change in the other. The body image system is dynamic, interactive, and so closely integrated that neither body image nor social relations have priority or precedence over the other. (Sault, p. 18)

The Effect of Mass Media on Latinos' Self Image

The willful perversion of facts relating to the representation of Latinos in the U.S. media is disgraceful, inconsiderate and extremely misleading and hence calls for immediate attention to prevent the degradation of a particular section of the society since their depiction and imagery in mass media plays a significant role in shaping their social identity and governs their self-esteem. Television and films both being dominant forms of media persistently depict racial stereotypes which are largely false representations of the

Baudrillard on Image or Illusion

...Baudrillard on Image, Illusion Our modern society is obsessed with the image in many different ways. The more our technology has progressed, the more we have found ways in which to create images in ways that are indiscernible from reality. Special effects in movies are defining the way that we view cinema, and televisions are built in such a way as to diminish the obviousness of watching an image on a screen. In other words, they are hoping to appear indecipherable from reality. The perfection of the image to some might be seen by some to be indicative of our progress, though there obviously are other ways to view this tendency. One person who concerned himself with this tendency to create an indecipherable image was the theorist...
