Abdominal Ultrasound Imaging, Pelvic Ultrasound Imaging, Obstetric Ultrasound Imaging, Doppler Ultrasound Imaging, 3-D and 4-D Ultrasound Imaging, Echocardiograms, Carotid and Abdominal Aorta Ultrasound Imaging are all different types of ultrasounds. Abdominal Ultrasound Imaging is used to examine internal organs, including liver, gallbladder, spleen, pancreas, kidneys, and bladder. They show movement of internal tissues and organs and allow physicians to see the flow of blood. This ultrasound can

Each imaging modality is characterized primarily as being able to render high-resolution images with good contrast resolution (anatomic imaging) or to render images that depict tissue function (functional imaging). Anatomic (Structural) Imaging Imaging the structure of the body has been and continues to be the major application of medical imaging, although, as described in 9.2.2, functional imaging is a very active area of research. The goal of anatomic imaging is to accurately depict the structure

Ultrasonic imaging is used widely for observing muscles and tissues beneath the human skin without physically breaking the skin barrier. Being non-invasive (Pinnacle Health, n.d.), it is suitable to be utilized by healthcare professionals as part of the entire suite of procedures for investigating aliments, ensuring there are no health problems, or to monitor the progress of recovery. A specific application of ultrasonic imaging is the Transthoracic Echocardiogram (TTE). Echocardiogram is an imaging procedure

tissues of the human body, avoiding annoying and aggressive procedures such as myelography (lumbar puncture), arthrography (introduction of contrast media in joints) and others involving aggression or discomfort to the patient. Magnetic resonance imaging is a diagnostic study in which no X-ray magnetic waves are used but this type of

Brain imaging technologies allow neuroscientists and neurologists the ability to see inside the brain through the use of different technology and techniques such as CAT, MRI, fMRI & EEG scans (Nigel Holt et al., 2012). With the information obtained neurologists/scientists to locate and determine areas of the brain and their relationship with the functions in the human body. Brain imaging technology also allows neurologists to locate possible areas in the brain that may be affected by neurological/psychiatric

Ultrasound imaging is required in a plethora of situations. They allow physicians to have a more in-depth glimpse of what is going on inside of patients’ bodies, and can therefore permit them to act accordingly. Of course, it is given that technology with such profound capabilities must be quite convoluted. However, to simplify, in can be condensed in six simple procedures. First, the ultrasound machine conducts high frequency pulses into your body through a probe. These waves traverse into your

Medical imaging refers to any process in a medical setting where the body is imaged to diagnose non-superficial injury or disease. The professional of medical imaging involves a variety of imaging techniques, two of the most common being Computed Tomography (CT), and Ultrasound scans. Medical imaging can be used for diagnostic (CT/Ultrasound) or therapeutic purposes, as is the case with Radiation Therapy which using ionising radiation to control malignant cells. Furthermore, medical imaging modalities

Magnetic resonance imaging (MRI) or Nuclear magnetic resonance imaging (NMR) is a non-ionizing imaging modality used for clinical imaging over the past 25-30 years. This imaging modality provides excellent soft tissue imaging with good contrast resolution in different parts of the body like brain, muscles etc compared to other ionizing modalities like CT (Computed tomography) and conventional radiography. The most important advantage of MRI compared to other imaging modalities is the fact it uses

Island.net, Nikola Tesla was the first to discover the rotating magnetic field that made magnetic resonance possible. MRI stands for Magnetic Resonance Imaging and is a medical test that physicians/doctors use to have a better understanding of a diagnose or to discover the diagnose. It is also used to treat medical conditions. This medical imaging technique uses radio waves, a magnetic field, and a computer to produce clear and detailed images of the inside boy. Such thing produces images of organs

Magnetic Resonance Imaging (MRI) is a medical exam used to image the body to help screen, diagnose, measure the success of medical treatments, and view the function of some organs. MRI uses a magnetic field, radio waves, and hydrogen nuclei within the human body to produce images. MRI does not use radiation to acquire images as many of the other imaging modalities do. Not using radiation is a benefit of MRI since radiation is cumulative, and there are always concerns of radiation induced cancers

The Basic Concepts of MRI: Magnetic Resonance Imaging Cindy Lu Saint John’s College Junior College Abstract MRI is ranked as one of the most rapidly advancing diagnostic imaging techniques used today. Though it is at the top, the hazards of it must be acknowledged, accepted and respected. The procedure itself is safe, but if there is a chance that it might go wrong, then it can go really wrong. Hence it is valuable to know the safety issues considered by radiologist, clinicians, physicians and

MR is a powerful imaging machine depend on the radio wave, unlike the other modalities which depend on the ionizing radiation. However, there are different sources of risk with magnetic resonance imaging, which the health providers should aware of (Dempsey, Condon, & Hadley, 2002). One of the main risks is ferromagnetic metal objects which can be projectiles with a strong static field. As the MRI develops and the magnetic field increases from 1.5 Tesla to 3 Tesla and more, as the power to pull the

There are a number of ways that brain activity can be measured and viewed, these vary from Magnetic Resonance Imaging (MRI) to lesion studies, each one having their own advantages and disadvantages. A lesion study can be construed as a method of the neuropsychologist to study the behaviour that is altered by the selected removal of one or more of the brain’s components (Gazzaniga et al., 2008, p.125). This method of study implements a unique insight into how the human brain generates emotion and

Functional magnetic resonance imaging (fMRI) is the scanning technique that examines the brain activity using the changes in the neuronal and cerebral blood flow. When haemoglobin is deoxygenated, it becomes paramagnetic (weakly attracted) and when it is oxygenated, it becomes diamagnetic (directed in 180 degrees towards magnet). Depending on the level of oxygenation, both of these slightly differ in magnetic resonance signal. Capillary red blood cells transfer oxygen to neurons, and when neurons

limitations about various segmentation methods will be discussed which methods have already discussed in chapter 2. First of all the need of segmentation over MR images should be known, though there are so many limitations presents in Magnetic Resonance Imaging (MRI) such as: Partial Volume Radio Frequency Noise Intensity homogeneities Gradients Motion Wrap Around Gibbs Ringing Susceptibility There are some disadvantages are also occurs in MRI: MR acquisition takes considerably longer time as compared to

Diagnostic imaging is one of the services the physicians use to optimize the patient management. It is a physician’s privilege where s/he owns the authority to recommend, order, and analyze this kind of diagnostic method. Are the physiotherapists qualified enough to own the privileging of diagnostic imaging as the physicians? Does the literature support this issue? What about the regulations and legislations that support or refute the right of physiotherapist to be a privileged in using diagnostic

Chapter 1 INTRODUCTION In medical science, imaging technology plays an important role in the diagnosis of the disease . It helps the doctor to see the interior part or portion of the body with ease which results in easy diagnosis i.e. doctor can make effective surgeries which is crucial for the diagnosis of disease and doctor can look inside easily without opening or closing too much part of the body. In the medical imaging there are different kind of alternates through which images are taken and

Radionuclide Imaging Radionuclide imaging is a process of scanning body using the elements that emit radiations. They are mixed with the chemical compounds, and these compounds get concentrated in the parts of body which are infected or the diseased areas of the body. The device known as GAMMA CAMERA produces an image to locate the Radionuclide particle. It is a technique of imaging the parts of body like various organs, bones, brain, etc. by using small doses of radioactive chemical particles which

Forensic imaging, particularly MRI technology is crucial in determining the cause of death in forensic pathology. There are a few main techniques for forensic imaging, magnetic resonance imaging (MRI), post-mortem computed tomography (PMCT), and conventional radiography. The PMCT is generally used for gunshot wounds, detection of gas embolism, trauma cases, and changes in the skeletal system. Some advantages of this technique are that it is fast, easy to handle, good three-dimensional reconstruction

“Live cell imaging” Introduction Live cell imaging is based on time laps images and it has various applications in biomedical and biology sciences (figure1). It gives spatial and temporal information as well as information about cell functions through monitoring and measuring the cellular dynamic process in biological structures. Successful live cell imaging is challenging as the cells needs to be kept at a good condition while making sure of the high quality imaging. There are different
