Medical imaging is the process and technique of creating visual representations of body interiors for medical intervention and clinical analysis. It is also the visual representation of the functioning of some tissues or organs(physiology). Medical imaging seeks to reveal the internal structures that are hidden by bones and skin and to treat diseases and diagnose. Medical imaging is known to establish a database of normal physiology and anatomy so as to identify abnormalities. We can do imaging of tissues and removed tissues and organs can be performed for medical reasons. These procedures are mainly considered part of pathology instead of medical imaging.
It is the process in which visual representation of the interior body for clinical analysis and medical intervention are created . Database of normal anatomy and physiology are established by medical imaging .
Main concepts of medical image are Radiog, projection radiolography , fluoroscopy , magnetic resonance imaging , nuclear medicine , ultrasound , elastrography .
Radiography : There are two types of radiographic images used in medical image - Projection radiography and fluoroscopy .
Fluoroscopy : It gives real time images of internal body structure .
Projection radiography : It is also known as x ray which is determine the type and extent of fracture in the body .
Magnetic resonance imaging : It is used to polarize and excite hydrogen nuclei in human tissues which produce detectable signals resulting in the form of body image .
Nuclear medicine : It is used for diagnostic imaging and treatment of disease. It is commonly known as molecular medicine or molecular imaging & therapeutics .
Ultra sound : It uses high frequency in the megahertz range to produce images .
Elastography : Elastography is useful in medical diagnoses . Quasistatic elastography , shear wave elasticity imaging . acoustic radiation force impulse imaging etc are the main branches of ultra sound elastography .
Benefits of medical imaging signal : health is improved , low cost etc .
Medical imaging signals is a part of biological imaging and well incorporated radiology that uses various imaging techniques of X-ray radiography, medical ultrasonography, magnetic resonance imaging, ultrasound, elastography, endoscopy, thermography, tactile imaging, nuclear medicine functional imaging and medical photography techniques as PET(Positron emission tomography) and SPECT(Single photon emission computed tomography).
There are recording techniques and measurement techniques that are not primarily designed to produce images such as magnetoencephalography (MEG), electroencephalography(EEG), electrocardiography (ECG) and other techniques which produces data that is susceptible to being represented as graph vs. time or maps that contain data about measurement locations. These technologies can be considered as forms of medical imaging in another discipline.
The major topics to study in medical imaging signals are X-ray and CT imaging, Medical image processing, enhancement, filtering, Medical Image Visualization, Magnetic Resonance Imaging, Tracking, Motion estimation problems, PET and SPECT Ultrasound Imaging , Validation, Image Guided Surgery, Image Guided Therapy Computer-aided diagnosis Other Applications etc.
