The Visual Representation of a Body Part in Imaging Technology

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 technicians use cutting-edge technology to create high quality, three dimensional images of organs and tissues inside the body to study

* Ultrasound. An ultrasound uses high-frequency sound waves to generate images of your internal organs, such as your kidneys and bladder, on a computer screen.

Ultrasound imaging has many uses in medicine, from confirming and dating a pregnancy to diagnosing certain conditions and guiding doctors through precise medical procedures

Another form of imaging is ultrasound. Ultrasound, which uses very high frequency sound, is directed into the body. And because the tissue interference's reflect sound, doctors are able to produce, by use of a computer, a photograph or moving image on a television. Ultrasound has many application uses on the body, but is more commonly used in examinations of the fetus during pregnancy, because use of radiation may affect the outcome of the baby. Some other practices for ultrasound include examination of the arteries, heart, pancreas, urinary system, ovaries, brain, and spinal cord. And because sound travels well through fluids it is a very useful technique for diagnosing cysts( which are filled with fluid), and fluid filled structures such as the bladder. And since sound is absorbed by air and bone it is impossible to use a ultrasound on bones or lungs.

- Even though the X-ray expose patient to harmful radiation it is used to see inside the human body and diagnose broken bones, gallstones and later tuberculosis.

I. Ordinary X-rays are used to diagnose many conditions and can be used to see a variety of things in the body,

An MRI uses computer-generated radio waves and a strong magnetic field to produce a detailed image of the brain. “MRIs are helpful in the diagnosis of tumors, eye diseases, infections, inflammation, and damage due to head injury” (Hill 2008). When getting an MRI, you lay on a table that slides into a tube, and they use computer-generated radio waves and a very strong magnetic field to see images of the brain. This test will allow the doctor to see two and three-dimensional images of your brain.

X-rays have numerous different effects on the tissues of the body, depending on the time of exposure and energy of the X-ray photons. Best contrast between different tissues is when the photon energy is about 30 keV, for diagnostic purposes. Resulting in the photoelectric effect dominating at this energy. The tissues absorb X-rays and electrons are released. The X-ray absorption depends on the number of protons in the nuclei of the atoms encountered. A high number will attenuate the beam, producing a strong x-ray shadow, enabling for a high quality image of

Healthcare has evolved tremendously over the last few decades. Technology, being one of the biggest impacts has reached new heights and has advanced our learning and knowledge to places unimaginable. Many different modalities take place in the health field to ensure the greatest treatment for everyone with improving outcomes. Three modalities that have enhanced and have taken special roles in 3-D imaging include, CT scans, MRI, and Ultrasound; each with their own advantages and disadvantages. These modalities all require training, are cost effective, and take a specific amount of time to obtain all the necessary information. These same modalities have different traits regarding the use of radiation, contrast, evidence

Medical ultrasound (also known as diagnostic sonography or ultrasonography) is an diagnostic imaging technique based on the application of ultrasound. It is used to see internal body structures such as tendons, muscles, joints, vessels and internal organs. The aim of often to find a source of a disease or to exclude any pathology. The practice of examining pregnant women using ultrasound is called obstetric ultrasound, and is widely used.

Magnetic resonance imaging (MRI) uses radio waves and a magnetic field to show images and structures in the human body. Because computerized tomography (CT) scans, ultrasounds and x-rays all have limitations on what images they can show, an MRI is often preferable to doctors when trying to diagnose what is wrong with a patient.

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

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.

Medical or Diagnostic Imaging refers to the various techniques that can be used to see inside the human body. Its non-invasive nature means that the body does not have to be opened up surgically for medical practitioners to view the organs anatomically. In clinical settings, it can be used to aid in the diagnosis or treatment of different ailments. Many kinds of medical imaging techniques have already been developed, each with their own advantages
