Thermal MR Injuries “The number of MR imaging related adverse events has increased steadily since the first years of clinical use, which may be due to the increase in the number of MR procedures” (Hardy& Weil, 2010). The primary type of adverse injuries is skin injuries. The Joint Commission and other organizations have raised awareness of skin injuries that are related to MR imaging. Technologists should always pay close attention to prevent accidents and injuries during MRI procedures.…

Medical Imaging and how the MRI Scan is used in the medical field today. Understanding Medical Imaging Medical Imaging has several different technologies that are used to view the human body. There are different types of Medical Imaging such as MRI, X-ray, CT, ultrasound, mammography, molecular imaging, and Pet Scan. Every medical imaging has a different image when using on the human body. The MRI uses a powerful magnetic field and radio waves to get detailed pictures of the internal body…

aligns all the Hydrogen protons in the body into one direction or plane i.e. to polarise the spin into one direction since all the atoms precess about their own axis. Once all the Hydrogen atoms are aligned along the same axis the Varying Coils labelled X, Y and Magnetic Z Coils in Figure 2 apply a second magnetic field of similar magnitude to the uniform field at a specific target location that is being investigated. The purpose of this is that it will flip the spins of a specific number of…

The best imagining device that would be best to use to localize the tumor in the man’s brain is the MRI. This is because the MRI, which is also known as the Magnetic Resonance Imaging, is a scanner that uses a powerful magnet and radio waves linked to a computer to create remarkably clear and detailed cross sectional images of the body. The MRI machine can be used to view, monitor or diagnose various things. It can be used to identify and monitor abnormalities of the brain and spinal cord, and…

Every year there are nearly 8 million bones broken a year, but who is going to be the one x-raying them? Well that’s where Radiologic Technology comes in. When you hear RT you will usually think oh that’s so easy all do you is look at bones and see where they are. We have 212 bones and we need to know every single one. We do more than look at bones. They also will do imaging exams like X-rays, computerized axial tomography, or CT, scans and mammograms. If you would ask any of the students…

variations of 3D reconstruction . 3D reconstruction is most commonly used by the medical field to examine the interior of the human body through a variety of different medical imaging technologies, such as MRIs, CT scans, ultrasounds, PET scans, and x-rays. In…

between need to be safe during any form of radiation treatment or procedure. So why are there careless mistakes of people being over exposed to radiation, when it can be so easily prevented? Unborn children are having full “babygram”, which is an x-ray of an infant’s entire body, and leaving sensitive organs exposed with no shielding (Bogdanich & Rebelo, 2011). Many other procedures that are commonly done are computed tomography, magnetic resonance imaging, and positron emission tomography.…

The position of the source is crucial for accurate treatment planning and delivery. The patient needs to be examined (through ultrasound, CT imaging, etc.) before treatment planning begins and before each treatment so that the geometry and positioning of the source to the intended target is precise and accurate. Each day before HDR treatment, the radiation therapist must utilize a departmental QA checklist. There are several components to this checklist. • Visual inspection of transfer…

CT scans is essentially a more in –depth X-ray that uses computer technology to gather a more detailed image that is cross-sectional. A CT scan offers the physician insight as to size, shape and longitudinal location of structures that lie deep inside the body such as organs, tissues and tumors…
