Darrlyn Duhe’ Linscott English 101 11 March 2013 Ultrasound Technicians Walking in a hospital setting there are a lot of interesting fields. One of the most interesting fields is Ultrasound Technician. Ultrasound Technicians perform medical diagnosis using high frequency sound waves and imaging techniques to generate images of cross sections of organs. Works under the direction of a radiologist. One amazing thing about Ultrasound Technicians is that they can see what goes on in a person’s body.
Duties and Responsibilities for being an ultrasound technician are very interesting but also demanding. For example, preparing patients for procedures by taking a patients history and answering any questions about the procedure. Record findings and also keep track of patient’s records. Also have to apply a gel to aid the sound waves’ ability to show the inside of the body. Recognizing the difference between normal and abnormal Images.
Another form of more sophisticated X-rays are CT Scans, computer tomography also known as Cat Scans. CT scans work very much like any other X-ray scan, but instead of having only a small burst of radiation sent through the body, numerous beams of X-rays are sent through the body and a set of electronic x-ray detectors rotate around the body, measuring the amount of radiation being
(Ahmed, et al., 2013) The gradient magnetic field comes about by the actual process of the MRI. The radiofrequency is switched on and off during an examination. Because of this the gradient magnetic field is born. These waves can produce a current in the pacemakers. They can cause the pacemaker to become faster or slower.
Magnetic Resonance imaging is accomplished through various measurements of this movement of the nuclear magnetic field. MRI contrast media are used to improve the visibility of internal body structures. These contrast agents alter the relaxation times of atoms within the body tissues. The most commonly used compound of contrast
This medical field is referred to as Sonography. Ultrasound uses sound (sonic) waves to capture images of the internal organs and tissues for the diagnosis and treatment of medical problems inside human beings. The Sonographer takes readings of the appropriate areas and angles that the physician had requested, and then sends the information back for interpretation. Unlike other diagnostic imagining system’s that use radiation, ultrasound is completely radiation free and is safe for both patients and ultrasound technicians. Knowing this little bit of information I’m sure questions are flaring up in your mind wondering what else Sonography has to offer for patients, and if still interested in learning more continue reading as for my facts about ultrasound will have your minds amazed about how technology has changed over the years and how it lets
MAGNETIC RESONANCE IMAGING PROCEDURE The world of medical imaging was still becoming accustomed to CT scan and ultrasound when a new way of imaging by using magnets and magnetic fields was invented. Some medical professionals wondered why they needed another test; radiologists and technicians were still trying to get used to the tests they had. But, the images produced by MRI were so spectacular, especially in areas that physicians could barely see before, like the knee, the shoulder, and other areas. Pictures of the brain, neck, and lower back were now visible from three different planes (axial, sagittal, coronal), as compared to the one (axial) that CT scan provided. There was no radiation and no serious side effects.
Investigating the various phenomena which occur when monochromatic light undergoes diffraction Title: Determine the wavelength of a monochromatic light source (laser). Measure the groove spacing of a CD and the diameter of powder spores using diffractive methods. Aim: The aims of this experiment are to determine the wavelength of the monochromatic light source and to determine the groove spacing of a CD and the diameter of the Lycopodium powder. Introduction: There are three parts to this experiment in the first part a diffraction grating is used to diffract light from a laser (monochromatic source of light). By measuring the angles of diffraction and by calculating the grating spacing, the wavelength of the light may be calculated.
Specialised laboratory Within this task I will describe what is required in a specialised laboratory and how these types of equipment will affect the progression of the lab in order for it to work to the best potential. This will explain the types of equipment will fit into this laboratory. Medical Laboratory This is a laboratory which tests are done on clinical specimens in order to get information about the health of a patient as pertaining to the diagnosis, treatment, and prevention of disease. Within this laboratory there are many types of equipment which are used like test tubes, a folin-Wu tube which is used for blood glucose determination, glass slides which are used with microscopes, a Petri dish, glass beakers, glass flasks, Pasteur pipette which is used for aspiration and addition of reagents, graduated pipettes which is again used to aspiration and addition of reagents but it if also it is often of minuscule amounts of the material where it is mainly used in colorimetry. They also use syringes and needles, disposable gloves, tourniquet which is used to cause an artificial venous stasis by applying pressure through this rubber tube.
Most diagnostic tests conducted in a Radiology Department expose patients using ionising radiation that are considered to be generally safe. There is no doubt that any radiation dose implicated could produce some form of effects on such individual. Hence, the purpose of radiation protection and safety programmes aim to prevent such unnecessary radiation exposures and to control the amount of exposure dose whenever is required. Even though it is necessary to reap the benefits on the use of radiation in the diagnosis of certain illnesses, it is still imperative to maintain the level of dosage to be at its minimum. This helps in reducing the patient’s lifetime risk of developing cancer while undergoing the different types of x-ray examinations.
