...Hellinger, J. C., & Epelman, M. (2010). Fetal MRI in the Third Dimension. Applied Radiology,39(7-8), 8-22. Ultrasonography is a primary diagnostic tool used in obstetrics for multiple reasons, but predominantly because it’s minimally inconvenient for the mother, and it produces dependable, prompt results. Ultrasound uses a 2-dimensional grayscale and Doppler static and cine techniques to achieve structural and functional information. Advantages of utilizing ultrasound is the aid in evaluating: facial abnormalities, neural tube defects, skeletal defects, congenital heart disease, the central nervous system, and fetal biometry. Magnetic resonance imaging (MRI) is advancing as a secondary diagnostic tool for both the fetus and the mother....

...problems arose that needed to be handled immediately. BACKGROUND Carl Robins, a new recruiter for ABC, Inc. hired 15 new trainees in early April to work for Operations Supervisor Monica Carrolls. Mr. Robins could not accomplish the necessary procedures for the new hires to begin work, including drug screenings, completing applications, providing materials and scheduling a facility in which to hold the new hires’ training. Monica Carrolls did contact Mr. Robins May 15 in regard to his responsibility in the hiring process, without verifying if he fully understood his duties, Mr. Robins did not give any indication he was having trouble completing the tasks either. Mr. Robins failed to have a current orientation manual on hand himself and previous employees had failed to keep a current master copy. KEY PROBLEMS Mr. Robins needs to address several problems to resolve the issue in order to meet his goal of having the new hires working by July. The key problems needed to be overcome before the new hires are to report to Mrs. Carrolls are the following four obstacles. First the incomplete trainee applications and transcripts files. Secondly the mandatory drug screenings were not scheduled. Thirdly incomplete orientation manuals must be handled. Lastly he must resolve the facility scheduling conflict. ALTERNATIVES With incomplete applications and transcripts on file, Mr....

...Brief History of Medical Imaging Medical imaging has played a very significant role in medicine for over the last one hundred years. It is one of the most important diagnostic tools available to doctors and has revolutionized the medical diagnosis of patients. The use of medical imaging has enabled doctors to see inside a patient without having to cut them open. Medical imaging, especially X-ray examinations and sonography which is also known to some as ultrasound, is essential in an everyday medical setting. Preventive medicine as well as healing medicine depends on the proper diagnosis and treatment by physicians, and the use of diagnostic imaging can help evaluate the course of a disease, as well as assess and document the disease in response to the treatment. Medical imaging has rapidly expanded from the first medical image discovered by Professor Wilhelm Conrad Roentgen. During a late night experiment in November of 1895, Roentgen, a physics professor from Germany, was examining Crookes tubes. He noticed that some light had managed to pass through a tube that he had wrapped in thin black cardboard, reflecting on the wall of his dark laboratory. Upon further investigation he found that the light could also be passed through paper, books, and eventually through human flesh. Unintentionally, he had stumbled upon a very important discovery that led to the discovery of what we now call an X-ray. One of the very first x-rays was one...

...Fundamentals of Ultrasonics - PLASTICS please click for enlargement Variations of Joint Designs or Energy Directors For the design of plastic parts for assembly with ultrasonic energy, many recommendations exist to save time, energy and tooling modifications. The first step for a designer is to determine the most suitable joining technique. The following variations are possible: Ultrasonic Welding Ultrasonic Swaging, Staking, Spot-Welding Ultrasonic Insertion Ultrasonic Welding The molten material builds at the contact area of the energy director between the to be welded parts. The ultrasonic waves are transferred through the part to the joint area. Common "standard" joint designs include: Basic 90 Degree Energy Director 90 Degree Energy Director Step Joint 90 Degree Energy Director Tongue & Groove Herrmann Ultrasonics Mash Joint Double V-Point Tongue & Groove The recommended process examples listed above can be varied with inserted gaskets or in-molded 2K injection molded gaskets.

...methods to treat and diagnose a patient. One similarity to these fields are that they both are one to one with the patient and you get to know the person a little better as they open up to you and tell you what is going on as they tell you their life stories. Sonography and Ultrasound is the same thing; it just has two names it can go by. In the late 1940’s and early 1950’s, three physicians discovered that sound waves were sent though the body with echoes from different tissues that would form different images of the anatomy of your body. Ultrasound is a sound beam that transfers energy from one point to another like an x-ray beam. These sound waves can only pass through matter and are small vibrations. If there is not matter for the waves to travel through, there is nothing for it to vibrate on and therefore the sound would not exist. There are three components used in Ultrasounds; transducer, the ultrasound beam and an image display on a cathode ray tube or on a screen where the picture is produced. A transducer has two main purposes: Senses the echoes that have returned from the previous pulses to produce the image and it transmits sound in pulses and bursts to create the picture. An ultrasound beam is where light bends and passes through different materials to create an image. A cathode ray tube is a high-vacuum tube in which cathode...

...Gray, Gabe Let’s talk Business Week one Individual work Mr. Davidson October 21, 2014 The six stages of the communication process consist of; encodes, sender, decodes, message, noise, feedback and receiver. There is a difference between listening and hearing. When you’re hearing your brain is registering sounds, vs. when you’re listening you’re actually paying attention to what is being said and trying to fully understand the full message. A huge situation going on today is the Ebola scandal, people are panicking and not actually listening to persuasions you can take. But the general public isn’t the only one not listening; unfortunately the nurses at hospitals aren’t taking full measurements to prevent this from spreading. If the first patient that went into the Texas hospital with the Ebola symptoms would have been taken care of then, it could have been prevented from spreading to others. We might not think about it on the daily, but the communication process plays an important role in our everyday life. Although the hospital has apologized for not taking better consideration of the first patient with Ebola, it doesn’t change the fact that now they have the whole country panicking. Yet again the communication process plays another big role, because if the general public would actually listen and understand how Ebola spreads they would know that you run a low chance of actually getting infected. People need to actually listen...

...Do the benefits of routine cancer screening outweigh the drawbacks? Living in the twenty-first century with all the medical technology available you would think one would be indestructible. Am I right? Scientist keeps coming up with cures, and modern machines seem to detect diseases early on. Or do they? Have you ever been given bad news just to find out later it was false? This has happened to most all of us sometime in our life. Somebody is being told today they have cancer. They have instantly been thrown into a sea of emotions, caught and knocked down by every wave of evil thought. They are eventually relieved that they had denied treatment only after finding out the test was wrong. All the worry this family went through could have been avoided. Some would go ahead with treatment, finding out later that they shouldn’t have. Don’t get me wrong, it is a great benefit to have all the modern updates of medical science at our fingertips. But, have we come to rely on the answers of machines rather than our own self-exams and our own intuition? Instead of being on a roller coaster of emotions, or taking dangerous amounts of unnecessary treatments, shouldn’t we wait until there’s a reason for concern and then use the force of science to combat the enemy? Until the ratio of routine screenings rise to meet a level of accuracy, I feel they are hardly as necessary as one is lead to believe. Routine cancer screenings bring too many false positives with premature and over...

...example is the most feared form of skin cancer: melanoma. Melanoma rates have gone up since the late 1980s. Most of the increase is in early cancers detected as skin-exam screening became more common. But late-stage melanoma cases didn't decline, Kramer says. Neither did the death rate. Brawley agrees. "I cannot quote a study showing that melanoma screening definitely saves lives," he says. "We cure some melanomas that don't need to be cured. “Nobody wants to live with cancer. Nobody wants to be over diagnosed or over treated. It's just that we want -- need -- answers that medical science does not yet have. "What we really need is a 21st century definition of cancer so we can move away from 20th century screening and diagnosis using a 1840s definition of cancer," Brawley says. There are limits to science, says Susan G. Fisher, PhD, professor and chair of public health sciences at the University of Rochester, N.Y. "People are uncomfortable and concerned because they think we are recommending less screening in some groups," she says. "The message for the public is that science is hard. As we get more and more information we get smarter about our advice. The most recent evidence says that in groups at low risk, we are creating more problems than benefits with early screening." The USPSTF recommends routine screening -- that is, for people at normal risk -- for only three...

...MGMT 404 week 3 O*Net Research Center 1. The occupation I was looking for was an Ultrasound technician. Ultrasound tech. was the second occupation that came up during my search. I think the information was comprehensive. The site gave specific information like salaries by state. I really liked the salary break down. The list of tasks is very close to what the ultrasound techs do at my office. They have to submit a report after every ultrasound that they complete. They also have to decide what images they are going to include in the clients portfolio. Before an ultrasound can began, the ultrasound tech. has to review the patient’s record to see if they are having a normal or abnormal pregnancy. Apart of the ultrasound tech. job is to understand the past problems that the client has had. The tools and technology used are also the same. In order to do an ultrasound the tech needs a machine, probe and the correct software. There is a great deal of knowledge that is needed to operate an ultrasound machine. Education, customer service, and physics are all things that an ultrasound tech. must have. The skills needed to work as a tech are speaking, active listening, monitoring, time management, operation monitoring. At my office we do fetal ultrasounds and it is important for the ultrasound techs to monitor the settings on the machine so they don’t become harmful to the unborn baby and mother. 2.

...it may not cause serious harm. While some types of prostate cancer grow slowly and may need minimal or no treatment, other types are aggressive and can spread quickly. Prostate cancer that is detected early — when it's still confined to the prostate gland — has a better chance of successful treatment. One of the biggest and prevalent issues with prostate cancer is the rates of sensitivity and specificity. Sensitivity and specificity measure the number of false positives and false negatives, and are useful in evaluating the effectiveness of screening methods. Sensitivity is the number of true positive results divided by the sum of the true positive results and false negative results. Specificity is the number of true negative results divided by the sum of the true negative results and false positive results. The article explains that the PSA test and Digital Rectal Examination (DRE) are the most widely used forms of prostate cancer screening. The PSA test is simply a blood test. Even though the PSA is widely available to the general population it’s the sensitivity is 34.9% and the specificity is 63.1% which is not good at all. The DRE test is available by appointment in a doctor's office; there is discomfort for the patient and a risk of slight bleeding. The sensitivity is 27.1% and the specificity is 49.0%, which is worse than the PSA test. To help ensure that the readings will be more reliable most doctors use the two tests together, the sensitivity remains low at 38.0%, and...

...Our third initiative will focus on partnering with the community, especially its leaders, in Brasilia, the capital city of Brazil. By building relationships with the community, we can create shared value as we help educate the population about the disease while marketing our product implicitly. Now, I am going to talk about why we chose Brasilia as our location and how we will carry this plan out. First of all, we decided to carry out this project in Brasilia because prostate cancer is the most common cancer for men in Brazil. But, the more important reason for selecting this location lies in that there are Brazilian leaders, who have had cancer, living in the region. To soften the market for our bigger expansion into South America in the future, it is important to respond to the culture there and interact with the community. When we attempt to enter the market in Brasilia, people can be on alert and oppose us since we are a foreign pharmaceutical company. In response, becoming friendly with the Brazilian leaders with some kind of connection to cancer will help the population accept our company better. In Brazil, the current president and ex-president have both suffered and recovered from cancer. So, we believe that these important figures obviously know the importance of treatments and of awareness of such diseases. And since they are major influencers that the citizens listen to, it would be easier to enter the market in Brasilia if we could get them in on our project....
