Essay On Image Processing - 977 Words

My research focuses on medical imaging and image processing to understand structure and brain function of both healthy and diseased brain. Specifically, some of my interests and expertise include: 1) developing improved MRI relaxometry methods and their applications towards diseased brain, 2) investigating the relationship between brain structure and function and cognitive performance in both healthy and diseased brain such as multiple sclerosis (MS), 3) investigating the neurophysiological bases of brain white matter signals; 4) developing potential biomarker for multiple sclerosis using iron sensitive MRI measures. Past Research: My PhD thesis combined the development of MRI methods and their applications to patients with MS. The main†¦show more content†¦This work addressed means to overcome the tissue heating limitations to enable more rapid multi-slice T2 mapping. The tissue heating limitations were overcome by shortening the echo train lengths. Consistent T2 values were found with as few as 4 refocusing RF pulses compared to 20 refocusing RF pulses. RF power savings through the use of reduced number of RF pulses enabled increased slice coverage. That means, using the improved method, MRI scan time can be reduced by 5 times compared to the previous method. This T2 mapping approach is useful for obtaining accurate T2 values in grey matter and white matter in the brain. These findings were originally published in [1] and [2]. Second, evaluate the iron dynamics in MS using improved T2 mapping method using 26 age- and sex-matched healthy volunteers and patients with multiple sclerosis. Compared to controls, the MS patients had smaller deep grey matter volumes and increased iron content in these structures over two years, but significant changes were found one the deep grey matter structures. This finding indicates, combination of atrophy and T2 measurements in deep grey matter can be used as biomarkers to monitor disease progression and dynamics of iron accumulation in MS. This work has been published as a conference proceeding [3] and then as journal article [4]. Third, we compared the benefits and limitations of different MRI relaxometry (T2, T2*, T2’ and FDRI, relaxometryShow MoreRelatedImage Processing Essay1065 Words   |  5 PagesINTRODUCTION In image processing, noise reduction and restoration of image is expected to enhance the qualitative inspection of an image and the performance criteria of quantitative image analysis methods Digital image is inclined to a variety of noise which attribute the quality of image. The main purpose of de-noising the image is to reinstate the detail of original image as much as possible. The criteria of the noise removal problem depends on the noise type by which the image is contaminatedRead MoreImage Processing Essay1097 Words   |  5 Pageslatency is going up. As we cannot measure everything with a scale or a tape, we use some optical methods of Image Processing. In this paper, we present an approach that can be used to determine the lengths and some other degrees of measurements like diameter, spline, Caliper(perpendicular angle) etc. We used mostly the Image Processing techniques because all the measurements are done on an Image. We also use some other techniques like Euclidean algorithm. Index Terms: - Spline, Euclidean algorithm,Read MoreWhile many people perceive images to be fully reliable, how the image is used is what really600 Words   |  3 PagesWhile many people perceive images to be fully reliable, how the image is used is what really determines its validity. In this essay I will be briefly demonstrating the different ways in which fMRI (functional magnetic resonance imaging) is used and how this brain imaging technology can help investigate the relationship between biological factors and behaviors of schizophrenia patients.

Do you think that the international business community is being too lax about the abuse of intellectual-property rights? Are international companies simply afraid to speak out for fear of jeopardizing access to attractive markets? Answer: It depends on the products. If the products are marketed for automotive parts which will affect people’s life such as break, fluids, filters, batteries etc. When consumers are in accident because of a ounterfeits products, the legitimate manufacturer needs to prove that the product is not their own and will be out of their responsibilities. In contrast, if the products are clothes that sell on the street, people who buy those products they know what they are buying that it’s not real. Buying cheap t-shirts which is very easy to shrink in laundry machine. Customer they know what they are getting for what they are paying the Answer: Yes, for example in China an international company has difficulty fighting piracy because filing a lawsuit can severely damage its business relations there. Since government officials are people who run the pirated company such as China’s national army operates factories who make pirated goods. In addition, criminals are often connected to political leaders and receive legal protection from prosecution. Then an international company who operates in China have to be very careful about that because it’s easily to be getting out of business. They have to control the genuine products to be sold in US, CANADA or AUSTRALIA only, then they can have their sales volume in particular basis. 3 . Increased digital communications may pose a threat to intellectual property because technology allows people to create perfect clones of original works. How do you think the Internet might affect intellectual—property laws? Answer: Since internet is very easy to access anywhere in the world, everything now becomes to be peer to peer system it’s very difficult for any kind of protections after getting online. However, Napster Software Company is made money by having people sign up for being memberships for free at the beginning, when more subscribers they start to charge for downloading songs, movies online in order to pay to the companies for patents, trademarks or copyrights.
