Essay On Image Fusion

The MRI equipment uses technology, which enables high-resolution 3D imaging with a lot of clarity. This technology makes it easier to detect and diagnose conditions such as blockages in blood

MRI uses the body’s natural magnetic properties to formulate an image of the soft tissues. It does this by using the hydrogen atom nucleus which has a single proton and is a spinning charged particle. The human body is made up of 70% water, which is hydrogen and oxygen. Those hydrogen nuclei (protons) spin inside the body, creating their own magnetic field. They are orientated randomly and cancel each other out when no field is applied.

Different maps are taken of the brain in order to determine if there are any problems with the brain. An electroencephalogram (EEG) is used an amplified read out of the brain waves. A magnetic resonance imaging scan (MRI) gives a detailed picture of the brain’s soft tissues. It also shows the structure of the brain. A function magnetic resonance imaging scan or function MRI (fMRI) shows the function of parts of the brain as well as the brain’s structure. It also has the ability to show when a person is lying. Scientists also use a neuroimaging technique called a positron emission tomography scan (PET scan) to view the brain. (Barron’s AP Psychology 6th Edition) The PET scan shows each brain area’s consumption of chemical fuel which is glucose. There is a scale for the PET scan to determine activity in the brain when performing a certain action. The colors range from purple to red, purple represents no activity while red represents very high activity. The PET scan can

During a brain MRI, a special mechanism called a head coil is placed around the patient's head to assist in producing very detailed images of the brain. The head coil does not touch the person, and the person can see through large gaps in the coil. A spine MRI is normally used to look for a herniated disk or narrowing of the spinal canal in patients with neck, arm, back, and leg pain. It is also the best examination to use to search for a recurrent disk herniation in a patient who has had prior back surgery. A bone and joint MRI can be used to check virtually all of the bones, joints, and soft tissues; it can be used to identify injured tendons, ligaments, muscles, cartilage, and bones. A MRI of the abdomen is most commonly used to look more specifically at an abnormality seen on another test, such as an ultrasound or a CT scan. The exam is usually customized to look at such organs as the liver, pancreas, or adrenal glands. For female patients, a pelvic MRI provides a more detailed look at the ovaries and uterus and is often used to follow up an abnormality seen on ultrasound. For male patients, a pelvic MRI is sometimes used to check those diagnosed with prostate cancer. Magnetic resonance angiography (MRA) depicts the blood vessels. The blood vessels in the neck and brain are often studied by MRA to look for areas of narrowing or widening. In the abdomen, the arteries supplying blood to the kidneys are also

Hospitals, Doctor offices, and many more use lots of different imaging methods daily to check on different parts of your body. From doing an X-ray to check on your bones, to a CT scan to check on the brain for hemorrhages, tumors, and atrophy. To an MRI is used to image soft tissues of the body like the heart and lungs (Timberlake, Karen p. 340). In this research paper, I will talk about 2 more different imaging methods and come more in depth with X-rays, CT scans, and MRI’s.

X- ray is electromagnetic radiation that penetrates structures within the body and creates images of these structures on photographic film or a fluorescent screen. Diagnostic x- ray is useful in detecting abnormalities within the body. They are a painless, non-invasive way to help diagnose problems such as broken bones, tumors, dental decay, and the presence of foreign bodies.

Medical imaging such as the x-ray work by shooting a x-ray beam at your body and on the other side of you they are detectors and it detects those waves which result in an image which ever part is not detected is your image. Many people may think a x-ray is a machine and that is true but a actual x-ray is a

Without the MRI there were many risks, the surgeries preformed were very high risk and not guaranteed to go well. Human’s risked their lives and others to find out possible medical issues they could have. The MRI was first invented by Raymond Damadian in 1977 to diagnose cancer.⁴ Although there were multiple scientists involved, such as Sir Peter Mansfield and Paul Lauterbur, Damadian was the one responsible for “the construction the first full-body human MR scanner.”¹ Lauterburg introduced the first true MR image in nature in March of 1973, with all his research and experimental setups, he was able to produce “crude images of his first living organism: a tiny clam.”¹ With multiple practices and much help, Mansfield developed the first human image, a finger in 1977, which was played a big part in his earning of the Noble Prize in Physiology and Medicine in 2003, where he shared with Lauterburg. Damadian saw the NMR scanner as something different than Lauterburg and Mansfield, he saw it as “phenomenon that might be used to probe the body and diagnose human disease.”¹ The image below represents the first full-body MR image produced mid-summer, 1977. Damadian was the first to commercially display his findings and reseach through his company

Positron emission tomography is used for research and medical diagnosis of soft tissue in humans and animals. It uses radioactive drug tracers that are swallowed, injected, or inhaled into the body, to produce radioactive emissions that are then detected with a computer tomographer (Mayo Clinic 2013). This computer tomographer creates an image much like a camera makes an image on film, when exposed to light (Denniston 2014). The scans are then used to produce three dimensional images that provide information on a targeted body system. When interpreting the images, diseased areas of an organ, are identified by dense regions of the radioactive drug tracer. Some of the area's of the body commonly scanned are blood, bone, brain,

Magnetic Resonance Imaging, or commonly known as MRI, is a technique used in medicine for producing images of tissues inside the body. It is an important diagnostic tool because it enables physicians to identify abnormal tissue without opening the body through surgery. MRI lets physicians see through bones and organs. MRI does not expose the patient to radiation, unlike tests that use X-rays. MRI provides an unparallel view inside the human body. It is the method of choice for the

Magnetic Resonance Imaging (MRI) is a diagnostic procedure technique that uses a magnetic field and radio waves to create detailed images of the organs and the tissues within the body (Mayo Clinic 2013 par.1). When the human body lies inside the MRI machine, the magnetic field temporarily

MRI uses radio waves and magnets to create images of your brain. Your doctor can use these images to identify damage to your brain tissue and cells that occurs due to stroke.

There are several types of MRI technique. One of them is Closed Magnetic Resonance technique. It uses a high magnetic field range, with ranges from 1.5 to 3 Tesla. The large magnetic field helps in showing some fine details. Another type of MRI is Open MRI, where a low magnetic range is used, between 0.23-0.3 Tesla. This technique is suitable for patients whose bodies can not tolerate being to examined by the high-range Closed MRI, such as being claustrophobic. This technique is one of the disadvantages that reduces the use of this technology for some patients. Another issue is with patients who have metal objects in their bodies. It causes them pain because of the magnetic field- making them scream sometimes out of pain, and sometimes raises

Last of the diagnostic imaging tools is the MRI. MRI, which stands for Magnetic Resonance Imaging, was a technique developed in the 1950?s by Felix Bloch, and is the most versatile, powerful, and sensitive tool in use. The process of MRI was originally called NRI, Nuclear Resonance Imaging, but was found to be to confusing due to the fact that MRI?s don?t use radioactivity and ionizing radiation. The MRI generates a very powerful electromagnetic field, which allows the radiologist to generate thin-section images of any part of the body. Also it can take these images from any direction or angle, and is done without and surgical invasion. Another plus side to the MRI is the time it takes to perform, where as a CAT scan may take 30-60 min. A MRI may only take 15 minutes max. The MRI also creates ?maps? of biochemical compounds within a cross-section of the body. These maps give basic biomedical and anatomical information that provides new knowledge and may allow early diagnosis of many diseases.

An MRI (magnetic resonance imaging) is a scan that uses a system of techniques, involving magnetism, radio waves and a computer to generate detailed images of the human body. Essentially, it is a tube encased by a large circular magnet. The patient would be placed on a moveable bed, which is then inserted into the tube. The magnet then creates a strong magnetic field that aligns the protons of hydrogen atoms. These hydrogen atoms come from the human body, which is 50-65% H2O. These atoms are exposed to a beam of radio waves. This spins the various protons of the body. As they spin, they produce a slight
