Computed Tomography, More Commonly Know Term Paper

… The technologist is also able to see and hear the patient, and if necessary will communicate with the patient over an intercom.

Several computers are used to control the entire CaT system (, 2004). The main computer that oversees the operation of the entire system is called the "host computer." There is also a dedicated computer that reconstructs the "raw CaT data" into an image. The CaT gantry and table have multiple microprocessors that control the rotation of the gantry, movement of the table, tilting of the gantry for angled images, and other functions such as turning the x-ray beam on and off. While a Cat scan may seem a hindrance to the patient, it is painless. If the exam involves uses of an intravenous…. [read more]

Positron Emission Tomography (Pet) Term Paper

… How Positron Emission Tomography Works.

The detection of the annihilation of radiation by the radiation detectors used in PET is the basis of the operation. Such detectors operate on the principle of "coincidence detection"; here, the external detection and localization of a positron emitter inside the brain takes advantage of the fact that the two annihilation photons travel in opposite directions. In addition, the system takes advantage of the fact that they also emerge simultaneously: "A coincidence circuit between pairs of opposite detectors arrayed about the imaged object records an event only if both detectors record an event simultaneously (N t nen, 1992, p. 95).

These so-called "coincidence circuits" are constructed in such a way that the signal from each detector is able to be…. [read more]

Alternative Approach to Computerized Tomography Article Review

… One is that it actually summarized the findings of literature from a fairly lengthy time period -- there are references to certain applications dating back to the 1980s. In this respect the article was extremely comprehensive in its scope, although perhaps it may have been better suited focusing on more contemporary applications. Still, for the variety of knowledge it covered and the degree of insight it shed, it is certainly an excellent starting point for research into this field, and helps to synthesize the various points of relevance of the other articles explicated within this assignment.

Kai Hung Fung Artwork Instrument Essay

… Limitations of Using Human Body over Alternative Mediums

It is not an easy job to use human body as an interactive instrument in ads as it sometimes might not explains the idea behind the ads. The human body might mislead from the actual ideas as people get distracted by the human body and not paying attention to the actual theme behind the ads that is why it is very difficult to use the human body as a communication instrument. However Fung has used human body in such a way that the onlooker is not led to a misguided direction and the basic theme of the art remains vividly perceptible to him.

Fung's use of human body as an interactive instrument works most of the times…. [read more]

Imaging and Optics Term Paper

… ¶ … Optics Applications in Information Technology Today

How imaging and optics technology are revolutionizing the way businesses communicate their products to the consumer.

Imaging and optics technology have provided a wide range of industries with the ability to label, track, and prevent bad documentation to their products for a more efficient and economically sound business.

Audience: College students, professors, general public.

Imaging and optic applications are truly ancient, and people quickly recognized the innovation these devices represented. "Two thousand years ago," Peter Weiss says, "Roman Emperor Nero peered through an emerald monocle to better see his gladiators in combat. Twelve hundred or so years later, eyeglasses started to adorn faces" (p. 200). To date, though, optical lenses have primarily served just one purpose: to…. [read more]

Brain Scans as Evidence Research Proposal

… Brain Scans as Evidence

"Brain images provide insight to understanding behavior.

Additionally, the images themselves carry great impact, particularly when used to show differences in either the anatomy or the biological functioning of two different brains.

For these reasons, brain images have increasingly been used

in both criminal and civil trials"

Even though images from brain scans may be used as "evidence" in trials, researchers regularly relate a number of concerns that currently challenge the perception the quote introducing this study asserts. In fact, lshani Ganguli (2007), Harvard University, cites Nancy Kanwisher, a professor of cognitive neuroscience at MIT, to assert in the article, lshani Ganguli "Watching the Brain Lie": "[Functional magnetic resonance imaging] fMRI Is a Messy Muddy Mixed Field...[That Requires] Extremely Well Trained….

Radiology Reducing Patient Exposure and Maintaining Image Quality Term Paper

… Radiology, Reducing Patient Exposure and Maintaining Image Quality

Radiology as a branch of medicine was born due to the pioneering effort of German physicist Wilhelm Roentgen who accidentally discovered X-rays while researching in his lab in 1895. The amazing benefit that X-rays offered to medical science was recognized and, with the research of French scientists Marie and Pierre Curie after the discovery of Roentgen, scientific and technological developments have resulted in the vital contribution which radiology has presently come to offer in the diagnosis and treatment of various ailments. Radiology is a diagnostic as well as a therapeutic instrument. In order to recognize diseases and other conditions inside the human body, diagnostic imaging makes use of several varied modalities like plain radiography, CT scanning, Magnetic…. [read more]

How Has Technology Impacted How Healthcare Is Ran Today and in the Future Thesis

… ¶ … Healthcare: How Technology Has Changed Medicine


The objective of this work is to examine how technology has effectively changed the practice of medicine.

(1) Electronic health record (EHR): Originally, the EHRs were viewed as electronic file cabinets to hold patient data from various sources however, they are now viewed as a part of an automated order-entry and patient-tracking system providing real-time access to patient data, as well as a continuous longitudinal record of their care.

(2) Computerized provider order entry (CPOE): CPOE in its basic form is typically a medication ordering and fulfillment system. More advanced CPOE will also include lab orders, radiology studies, procedures, discharges, transfers, and referrals.

(3) Clinical decision support system (CDSS): CDSS provides physicians and nurses with real-time…. [read more]
