Computed tomography, more commonly know as a CT or CT scan, is an X-ray technique that is used to produce very detailed images of internal organs located in various parts of the body, such as the head, chest, and abdomen. Doctors use the images produced through this procedure to help diagnose and treat diseases. Other terms for the technique are also called computerized tomography or computerized axial tomography (CAT). While conventional X-ray exams produce two-dimensional images, CT scans uses an X-ray-sensing unit that rotates around your body and a large computer to create cross-sectional images of the inside of your body. This paper will address vital educational information including a brief history, uses for computed tomography, and the effects that it may have on the patient.
Computed Tomography

Brief History

British engineer, Godfrey Hounsfield of EMI Laboratories, England and Allan Cormack of Tufts University in Massachusetts invented computed tomography. Their work led to….

The recent two reported cases also suggest that there may be many more similar incidences happening around unnoticed. The two contrasting examples of overdoses of radiation at hospitals confirms that if the hospitals accept their responsibilities properly and try to serve the patient's in professional manner, such types of accidental over exposure can be avoided.
Instead of creating a medical terror, the reporter managed to provide relevant information in a progressive manner. He informed how many other advanced hospitals are trying to approach Cedars-Sinai Medical Center in Los Angeles to discuss about the issue and to check their own equipments and protocol to avoid such incidences. Furthermore, the FDA has also issued notices and alerts for all the medical facilities that use CT imaging to review their procedures and to avoid such incidences. The article further infuse positive approach by reporting about the Cedar Sinai investigation and their demand from….

Computed Tomography (CT)Basic Fundamentals of ModalityComputer modality is the interaction between computers and humans, which can be unimodal or multi-modal (Karray et al., 2008). The fundamentals involve the usability of this interaction along with functionality. Functionality determines whether the purpose for which the interaction between humans and computer takes place is fulfilled or not. Usability is whether the adequate accomplishment of goals for which the interaction is created is effective in its range and degree. Humans use the most sophisticated machines, but there is no interaction if the purpose is not satisfied.How Images are ProducedThe images are produced by computerized x-ray beams coming out of the x-ray machines in computed tomography (CT) (National Institute of Biomedical Imaging and Bioengineering-a, n.a.). The light beams are aimed at a specific body area for which an x-ray is required. This main computer modality fulfills some purpose with interaction with humans. The signals created….

Conventional Tomography outlining the various aspects, issues and methods used. It has 10 sources.
The field of medical imaging has been in existence for over one hundred years but new research and scientific breakthroughs have changed both its image and its role. adiology is not only diagnostic but is expanding to encompass curative techniques as well. The most common radiological investigation remains the conventional X-ray but a wide range of new and more efficient modalities have also been available for the past several decades. Amongst these methods is tomography, specifically in reference to this paper, Conventional Tomography.

Conventional Tomography:

Principle

adiographs deal with the internal anatomy of bodies, commonly used to view bones, calcified material, and soft tissue masses. This area has branched out since the use of fluorescent dyes but still is limited by the fact that a conventional radiography is unable to display within the framework of two-dimensional x-ray picture all….

Positron Emission Tomography (PET)
PET represents a new step forward in the way scientists and doctors look at the brain and how it functions. An X-ray or a CT scan shows only structural details within the brain. The PET scanner gives us a picture of the brain at work. - What is PET?

The epigraph above is reflective of the enthusiasm being generated among clinicians concerning the advent of positron emission tomography and its potential for imaging the human brain. The introduction of sophisticated neuroimaging techniques such as computerized tomography and magnetic resonance imaging has shifted the emphasis of neuropsychology from lesion localization to diagnosing the etiology of diseases (Maruish & Moses, 1997).

Behavioral neurology also benefited from innovations in neuroimaging techniques. The advent of improvements in the imaging of brain anatomy through computed tomography (CT) and magnetic resonance imaging (MI), as well as functional imaging with single photon emission computed tomography (SPECT),….

Extant literature has been dedicated to the evaluation of closed head injuries using the Canadian Scale and New Orleans criteria for Adult patients in rural areas.The work of Stielle et al. (2005) explored the comparison of the Canadian CT head rule and the New Orleans Criteria in various Patients suffering from minor head injuries. Their work indicated that the current application of computed tomography (CT) for cases of minor head injury is rapidly increasing.This technique is further noted to be inefficient and highly variable in its actual application. The Canadian CT Head ule (CCH) as well as New Orleans Criteria (NOC) are clinical decision rules that bwere previously developed in order to guide CT use for the patients suffering from minor head injury while also recording a Glasgow Coma Scale (GCS) scores of between 13-15 for the CCH as well as a score of 15 on the NOC scale. Stielle….

The advantages of the system can be numerous. One of them is better image quality, wherein better trabecular details would be seen; another advantage is that there is absolutely no need for retakes. This would save time and money, as well as avoid additional radiation for the patient. There will also be no loss of films, because there is no danger of these images being misplaced or lost, unlike as in the case of conventional x-rays. It is also possible to obtain multiple images with one single exposure, and the images can be manipulated according to the need of the attending physician/s. In addition, it is also possible to obtain multiple images on one film, and images can also be provided on medium other than film, like for example, on a CD, on paper, or they can even be viewed on a monitor. These are some….

InVision

Children's Hospital of Philadelphia (CHOP) has recently constructed an ultramodern pediatric imaging facility. The healthcare facility exclusively focuses its improved services on children's imaging. In this paper, we present a marketing approach that covers computed Tomography (CT), fluoroscopy, General radiology (X-ay), Magnetic resonance Imaging (MI), Nuclear Medicine as well as ultrasound. The work includes an assessment of both the internal as well as external environment which is important in allowing us to determine the full advantage associated with the CHOP brand, the strategic location of the facility as well as the purchase of the new and improved equipment to warrant the integrated marketing strategy. The approach is however, threatened by the existence of another major hospital within Philadelphia that also offers pediatric imaging services. This risk will however be mitigated by CHOP's approach of focusing on pediatric imaging at an affordable price. Pediatric imaging is to form CHOP's niche….

Certainly, it must be stated that more study is needed and worth pursuing in this diagnostic method in forensics.

Based on etiologic differences, male-to-female ratio is 1.5-3:1. Primary biliary cirrhosis accounting for only 1.5% of deaths from cirrhosis is mostly found in females and ethanol-related cirrhosis is greatly found in males. Age-specific death rates in the United States tend to be greatest in the older age groups, topping at 49 per 100,000 males aged from 65-74 years and at 26.7 per 100,000 women of the age group from 75-84 years. (Cirrhosis: (www.emedicine.com)
Diagnosis and Imaging Modalities:

Ultrasound, computed tomography, magnetic resonance imaging, and angiography are suggested as imaging modalities for the diagnosis of liver cirrhosis. In cases of patients doubtful for diffuse liver disease, ultrasound of the liver is being used as a screening-imaging tool and it is useful in for follow-up examinations. In order to make the presence of liver disease to be clear, computed tomography is usually carried out and it is detected by ultrasound. Against this background,….

Breast Cancer and Imaging
There are still a number of cases where women who have been diagnosed with breast cancer exhibit metastatic disease at the first presentation, this despite the fact that there have been significant steps made towards early detection of breast cancer. In the United States alone, five percent of such cases have been reported with a further thirty percent of women with early-stage, non-metastatic breast cancer at diagnosis having the possibility of developing distant metastatic disease. A cure has not been found for metastatic breast cancer, however the introduction of newer systematic therapies has led to significant improvements in survival (Scott, 2015).

What is breast cancer?

Cancers are named depending on the location of such mass of tissue, therefore when the cell division and growth in the breast is abnormal there occurs breast cancer. Most of these abnormal cell growth happen slowly and over time before they could be detected,….

Educational development is a mix of both formal and informal learning conditions as assessment of my own educational experience has taught me. I cannot say that one is more important than the other; each segment together has taught me different elements -- made me grow -- and combined in producing the 'me' that you see today.
In his "Notes for an Obituary," Einstein once noted that the system of education was a deliberate intention on the part of the state to mislead youth. He distrusted all forms of education, and from his pre-adolescent days refused to be taught. Religious leaders, too, he felt were disillusioned and deluding society. Yet Einstein felt that the fault belonged, not to the rabbi or to the priest, but with the force behind them that disregarded liberty of thought and made education compulsory. As regards Einstein himself, he was determined that formal education would not teach….

practitioner in a family medical practice, a physician will see an assortment of ailments. Many inflicted individuals first seek aid in a family practice setting. From that point multiple outcomes and referrals are possible. The treatment can also vary greatly. Treatment can range from a simple dose of antibiotics to surgery. In this aspect, family clinics and physicians are of great importance in American society. Branchial cleft cysts are fairly uncommon and there are three known types. As it is the result of a recessive genetic disorder, both parents must be carries for the ailment. "The birth defect may appear as open spaces called cleft sinuses, which may develop on one or both sides of the neck. A branchial cleft cyst may form from fluid drained from a sinus. The cyst or sinus can become infected" (McGuirt, 2005). This type of cyst is generally composed of squamous or columnar….
