The coil is the part of the machine that will actually make it work, by giving of a radio frequency. The scanner uses hydrogen atoms to tell the difference between different tissues. MRI scanners will use ‘spin’ which is a property in the machine which can tell the differences between tissues, such as fat, tendons, and muscle. Once the MRI scanner is turned on and the patient is in ready to be scanned the nuclei of the hydrogen atoms in the machine can spin in one of two different directions. The hydrogen atom nuclei can change the direction of spin to the opposite direction.
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.
Radiologist technologist are very important to the society because with the knowledge of taking the x-rays, MRIs, CAT scans, and Ultrasounds we can help in the diagnosis process. From broken bones, to tumors in the brain, to a baby still in the womb, we can look at what is going on in someone if there is a
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.
Types of Robotic Surgery Robotic surgery allows surgeons to perform many complex procedures with more precision, flexibility, and control than standard surgical techniques (Mayo Clinic Staff, 2011). There are several types of robotic surgeries that are used for many conditions. This section will cover three areas and the conditions that fall under each of those areas. The areas to be covered are robotic abdominal surgery, including colon and rectal surgery, robotic cardiovascular surgery, and robotic urologic surgery. Robotic abdominal surgery, and colon and rectal surgery are used to treat conditions like the following: gallbladder cancer, liver cancer, and pancreatic disorders.
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
It serves as a guiding tool during stent placement and peripheral interventions. It allows the assessment of possible intra - or postoperative complications. With the aid of IVUS, disease progression and regression can be determined, cardiac transplant status can be evaluated and IVUS can be utelized in clinical research. The most common IVUS imaging is done on the coronary arteries. EUS-guided angiotherapy makes intravascular therapy possible and is done in conjunction with real time ultrasound investigation of thrombosis and hemostasis (Buthani,
These are based on the presence of characteristic neurological and neuropsychological features and the absence of alternative conditions. To exclude other cerebral pathology or subtypes of dementia, advanced medical imaging with computed tomography (CT) or magnetic resonance imaging (MRI), and with single photon emission computed tomography (SPECT) or positron emission tomography (PET) can be used. This diagnosis may predict conversion from prodromal stages (mild cognitive impairment) to Alzheimer's disease. Thus an assessment of intellectual functioning including memory testing can further characterize the state of the disease. Medical organizations have created diagnostic criteria to ease and standardize the diagnostic process for practicing physicians.
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.
