Abstract
In the last decade, computed tomography (CT) has undergone major advances and the development of multi-slice computed tomography can be considered as revolutionary because it has not only enhanced diagnostic imaging capabilities, but also ensured better patient compliance and comfort. The paper explores the numerous advantages that multi-slice computed tomography offers, the current applications of multi-slice computed tomography, future trends and also attempts to determine if there are any drawbacks to this procedure. A table and a number of photographs are included after the bibliography.

"The continuous evolution of computed tomography has seen many technological improvements, and multi-slice computed tomography is one such revolutionary development. It has numerous advantages like faster acquisition speed, reduced artifacts, reduced need for contrast, high resolution images etc. Although this imaging modality has some drawbacks like increased radiation exposure, and difficulty in reviewing, reporting and archiving data, the benefits clearly outweigh the disadvantages.
"The clinical applications of multi-slice computed tomography include the ability to detect small lung nodules, visualization of cranial vessels and aneurysms, cardiac imaging and virtual colonoscopy. The future trends in development will include functional and perfusion imaging, advanced image processing and computer-aided diagnosis programs. Problems like noise and excess radiation exposure is likely to be tackled effectively."

Abstract
This paper describes and explains the procedure of multi-slice computed tomography and then gives an overview of its advantages and disadvantages as compared to other imaging methods. The paper also discusses the clinical applications of multi-slice computed tomography and describes its future trends. This essay includes illustrations after the References page.

From the Paper
"In the last decade, computed tomography (CT) has undergone two major advances: the introduction of helical computed tomography imaging in 1990 and multi-detector computed tomography in 1998. The development of multi-slice computed tomography can be truly be considered as revolutionary because it has not only enhanced diagnostic imaging capabilities, but also ensured better patient compliance and comfort. Although the principles of a multi-slice computed tomography (MSCT) is similar to that of helical computed tomography, there are greater advantages with a multi-slice computed tomography, when compared to other imaging methods like single-slice computed tomography. Briefly, multi-slice computed tomography means that the scanner can acquire more than one slice at a time. This is possible because the detector system is composed of more than a single row of detector elements (Attachment B)."

History
In conventional radiology, anatomy is depicted in only two dimensions. The depth or thickness of structures cannot be measured on projection images. For a comprehensive evaluation of morphology of a structure, data related to the third dimension are essential. For nearly three quarters of a century, multiple, different angle views were used in routine radiography to gain three-dimensional perception of structures through triangulation. In a continuing quest for methods to access data in the third dimension, techniques such as stereoscopic pair image acquisition and tomography were developed. Although they were highly valuable technical advancements, they still could not provide accurate quantitative information in all three dimensions of a volume structure."

From the Paper
"The use of computed tomography (CT) and magnetic resonance imaging (MRI) present both advantages and disadvantages relative to imaging for the diagnosis of brain disorders. While the MRI typically yields superior visibility of the suspected brain tumor mass, CT is superior to the use of radionuclide scans to set primary intracranial lesions. Further, while MRI does not "see" (image) bone, thus making it superior to CT for suspected intracranial brain tumor, its viability in scanning for vascular disease is as of yet unproved. In addition to these, contrast- ... "

"The PCs produced by competitors were cheaper, but similar to IBM PCs. This led to the development of PCs all over the world, and due to the designing by IBM the products look extremely professional. Today, these products are the Windows operating system and Intel CPU computers. At the same time, it is important to note that within one year IBM had succeeded in selling 200,000 IBM PCs. This is a very large number when compared to 46 UNIVAC computers that were sold. In the same year, 1982, Compaq launched their PC and it was 100 percent compatible with IBM. They had to spend $1 million to develop the ROM BIOS that made it similar to IBM PCs, and which did not yet violate the copyright held by IBM. "

Abstract
The writer of this paper focuses on the basic functions of the computer, which is primarily a data processor designed to accept input data and instructions, while remembering the data by holding it in memory cells. This paper details the software and technology involved in operating either a home or business computer. The writer contends that computer hardware is a heterogeneous ensemble of input devices, output devices, circuitry and memory. The most important component of any computer is the central processing unit (CPU), which is designed to process information and perform specific operations. This paper examines the advances in various forms of technologies used in computers since the introduction of the first electronic, general-purpose computers of the 1940s. The writer clearly explains how each element of the computer is used, for example: The memory located in the hard drive is a sequence of numbered cells, each containing a piece of information. The rule is that the content of a memory cell is changeable at any time and that memory is similar to a scratchpad rather than a stone tablet. The writer also details the significance of the operating system, which is the most important component of the software system.

From the Paper
"As far as software is concerned, it can safely be said that a computer will always need at least one program running at all times to operate. Under what is supposed to be a normal operation, referring to the typical general-purpose computer, the program described above is the operating system (OS). The operating system has the job to decide which programs are run, when that particular event happens, and has to allocate resources, such as memory or input/output - I/O to these programs. Hardware and other programs would not function without an operating system, which actually provides a layer of abstraction over the hardware, thereby facilitating the access of other programs to the resources of the computer, such as code ("drivers") which enable programmers to write programs for a machine without being obligated to know the intimate details of all electronic devices attached to the computer."

From the Paper
"Dell Computers is a for-profit manufacturer of personal computers. Early on in its corporate history, Dell Computers made its name in the PC industry by offering a unique custom configuration of personal computers and portables. Thus, Dell made its mark by developing distinctive competencies in the then still-evolving PC market of the 1980's. The then, small, Texas based firm resolved to show to the world that Dell Computers was not simply technologically astute-in fact, the company placed a rather low priority upon this aspect of Dell in its marketing, pricing, promotions, and placement in the PC market. The company did not emphasize that Dell was on the cutting edge of every new technical development. Rather, the Dell Company stressed that the company had sound knowledge of how to manufacture, design, and market its products or services effectively in a way to keep costs low for the average consumer or small business."

Abstract
This paper looks at the history of Dell Computers, from its beginnings to the present day, and examines how Michael Dell and Dell Computer Corporation have survived the competition and challenges of the computer industry while other computer companies have floundered. The paper includes a look at some of Michael Dell's personal traits, Dell Computer Corporation's direct model approach to doing business, how Dell Computer fares today, and Dell's global strategies.

From the Paper
"Michael Dell has always been precocious and interested in advancing his knowledge. When he was an 8-year-old third grader, he wrote to a company that advertised he could "earn his high school diploma by passing one simple test. The woman who came to administer the test was surprised when a child appeared wearing a red terry-cloth bathrobe (Maney, 1999)." This was just the beginning of one of the most successful computer companies today."
