Abstract- Ultrasound is one of the most popular medical imaging technologies that can help a physician evaluate, diagnose and treat medical conditions. Although ultrasound imaging is generally considered good medical tool but the overall detection rate of Congenital Heart Defects (CHD) using ultrasound image remain anomic. Congenital Heart Defects are the heart problem that occurs before birth. Recognizing Congenital Heart Defects at right time is a difficult task for Physicians due to lack of subject specialists or inexperience with the previous cases or even as the children they can’t express their problem in a proper way. In order to improve the diagnosis accuracy and to reduce the diagnosis time, it has become a demanding issue to develop an efficient and reliable medical Decision Support System.
(47) However, antibiotic administration increases the prevalence of antibiotic-resistant bacteria, and predisposes the patient to infection with organisms such as Clostridium difficile, a cause of antibiotic-associated colitis. (15) It is evident that there is excessive and inappropriate use of antibiotics especially in the prevention and treatment of hospital-acquired infections, including SSI prophylaxis. (48) In the latter case, timing of administration of the first dose is a corner stone to success. (49, 50) Yet administeration usually occurs at the wrong time and duration lasts for too long which affects the cost of patient care. It was shown by several studies that the local implementation of practice guidelines can yield significant improvements in antibiotic use and the cost of surgical
Physics and Engineering 2 Labs Laboratory Report Lab 10: Basic Optics Aleksei Kim Aibat Zhakeyev Alisher Urazbekov Experiment 1: Reflection Abstract: Procedure: The light source is placed on a blank sheet of paper and turned the wheel to select a single ray. In front of the ray we place the mirror on the paper. We need to see the incident and reflected rays, that is why we place the plane surface of the mirror in the path of the incident ray at an appropriate angle. On the paper, trace and label the surface of the plane mirror and the incident and reflected rays. Indicate the incoming and the outgoing rays with arrows in the appropriate directions.
It is possible to focus the microscope on this upper surface by focusing on a piece of dust on the lens. The side of the plano-convex lens with curvature was easily identified by placing it on a flat surface and pressing downwards on its outside edges, if it wobbled when pressed this suggested it was on the curved side. It was necessary to do this as the experiment requires that the curved face be in contact with the optical flat. The mount containing the glass plate, optical flat, and the plano-convex lens was moved until the centre of the fringe was at the intersection of the cross hairs of the microscope. The central dark fringe of the produced interference pattern is the
A RARE CASE: AN ADVANCED STAGE HEPATOCELLULAR CARCİNOMA PATİENT PRESENTED WİTH MULTİPLE SPLENİC METASTASES SUMMARY: Hepatocellular carcinoma is the most common primary liver tumor and it is one of the most common cause of deaths in patients with cirhosis. İt’s histopathologic diagnosis is difficult because biopsy usually couldn’t perform due to risc of bleeding. Clinicians especially diagnose it with radiologic and clinical parameters of patient. Splenic metastases are rarely conditions. But when its present we should make an examination for finding primary tumor.
These signals travel through a medium in the body and after striking with various tissues, return back to the transducer. Then the returned signals are processed and displayed on the screen, as either a real image or different artefacts. Using an ultrasound, this is a simplified way of understanding an image acquisition. In the following text, the principles of ultrasound generation from a piezoelectric crystal and physical properties governing image creation are discussed, with appropriate
Chapter 2 Literature Survey Diabetic retinopathy is a serious disease which results from complications that arises in case of the diabetic patient. A device called fundus camera is used to record image of the patient's eye. With the help of the fundus image the trained professionals look for the signs of DR i.e. microaneurysms. It is not a easy job to do and it requires a lot of expertise and man hour to get a accurate result.
Cerebrum growth is quite often deadly and could prompt to a suite of other medical issues. Because of its exceedingly unpredictable nature, mind disease study is going ahead at a moderate pace. The main 3 reasons for mind tumor are: DNA Mutation Tumor happens when the cell loses its capacity to bite the dust. In plain talking, the cells get to be everlasting. What's more, they begin duplicating rapidly and multiply at incredible velocities.
CTA generates 3D images within minutes on the workstation. Rapid treatment planning (Saba, 2013. Stephen, 2011) Disadvantages: At times CTA may require larger volume of contrast than DSA. CTA cannot delineate vessels as small as 3-5 mm and those close to the bones due to artefacts. Cerebral veins may appear as clear as arteries hence making interpretation difficult for the radiologist.
In the feature based method, finding the facial feature such as nose, eyes brows, eyes pupil and lips. In image based method there is scanning of image which looks like face. In Eye detection there is a Regression approach, Bayesian approach . There is also webcam based eye detection approach. In this technique the mean gradient vector algorithm is used to detect the eye ball center.
