"Medical imaging is the technique and process of imaging the interior of a body for clinical analysis and medical intervention."
Use of various imaging modalities to create visual representations of internal structures and functions, most commonly used in diagnosis and treatment planning.
Anatomy and Physiology: Understanding the structure and function of the human body is crucial when interpreting medical images.
Imaging modalities: Learning the principles and characteristics of different imaging modalities, such as X-ray, ultrasound, CT, MRI, PET, SPECT, etc.
Image acquisition and processing: The process of acquiring high-quality images and preprocessing them to enhance their quality and extract relevant features.
Image analysis: The methods and algorithms for analyzing and interpreting medical images, including image segmentation, feature extraction, classification, and quantification.
Image visualization: Techniques for visualizing medical images and exploiting their 3D information, including volume rendering, surface reconstruction, and virtual reality.
Radiation safety: Understanding the potential risks and benefits of ionizing radiation and how to minimize exposure to patients and clinicians.
Clinical applications: The use of medical imaging in various clinical applications, such as diagnosis, prognosis, treatment planning, and guiding interventions.
Image-guided therapy: The integration of medical imaging with therapy devices or procedures, such as image-guided surgery, radiation therapy, and drug delivery.
Image databases: The creation and management of large-scale medical image databases, including data storage, retrieval, sharing, and privacy/security issues.
Artificial intelligence and machine learning: The use of AI and ML techniques for automated image analysis, decision-making, and discovery of new knowledge in medical imaging.
X-ray: X-ray imaging involves the use of low-dose radiation to produce an image of the body's internal structures. This is one of the most common types of medical imaging, particularly for bone fractures.
Computed Tomography (CT): CT imaging combines multiple X-ray images to create a detailed image of the body's internal structures. This type of imaging is particularly useful for diagnosing cancers and detecting vascular diseases.
Magnetic Resonance Imaging (MRI): MRI uses a strong magnetic field and radio waves to produce an image of the body's internal structures. It is particularly useful for diagnosing soft tissue injuries, brain disorders, and musculoskeletal diseases.
Ultrasound: Ultrasound uses high-frequency sound waves to create an image of the body's internal structures. It is commonly used for prenatal imaging, heart imaging, and evaluating blood flow.
Nuclear Medicine: Nuclear medicine involves the use of small amounts of radioactive material to create an image of the body's internal structures. This type of imaging is particularly useful for detecting cancers, cardiovascular diseases, and neurological disorders.
Positron Emission Tomography (PET): PET imaging involves the injection of a small amount of radioactive material to create an image of the body's internal structures. It is particularly useful for detecting cancers and neurological disorders.
Single Photon Emission Computed Tomography (SPECT): SPECT imaging is similar to PET imaging but involves the injection of a different radioactive material to produce an image of the body's internal structures. It is also used primarily for detecting cancers and neurological disorders.
Fluoroscopy: Fluoroscopy involves the use of X-ray radiation to produce real-time images of the body's internal structures. It is commonly used for guiding surgical procedures, such as the insertion of a catheter or the removal of a foreign object.
Optical Coherence Tomography (OCT): OCT uses light waves to produce an image of the body's internal structures. It is commonly used for ophthalmic imaging, dermatology, and cardiovascular imaging.
Endoscopy: Endoscopy involves the insertion of a small camera into the body to produce an image of the internal structures. It is commonly used for gastrointestinal imaging, bronchoscopy, and laparoscopy.
"Medical imaging seeks to reveal internal structures hidden by the skin and bones, as well as to diagnose and treat disease."
"Medical imaging also establishes a database of normal anatomy and physiology to make it possible to identify abnormalities."
"Electroencephalography (EEG), magnetoencephalography (MEG), electrocardiography (ECG), and others."
"These technologies can be considered forms of medical imaging in another discipline of medical instrumentation."
"As of 2010, 5 billion medical imaging studies had been conducted worldwide."
"Radiation exposure from medical imaging in 2006 made up about 50% of total ionizing radiation exposure in the United States."
"Medical imaging equipment is manufactured using technology from the semiconductor industry, including CMOS integrated circuit chips, power semiconductor devices, sensors, and processors."
"As of 2015, annual shipments of medical imaging chips amount to 46 million units."
"In the case of medical ultrasound, the probe consists of ultrasonic pressure waves and echoes that go inside the tissue to show the internal structure."
"The term 'noninvasive' is used to denote a procedure where no instrument is introduced into a patient's body."
"No instrument is introduced into a patient's body, which is the case for most imaging techniques used."
"Medical imaging is the technique and process of imaging the interior of a body for clinical analysis and medical intervention."

"Medical imaging seeks to reveal internal structures hidden by the skin and bones, as well as to diagnose and treat disease."
"Medical imaging also establishes a database of normal anatomy and physiology to make it possible to identify abnormalities."
"Although imaging of removed organs and tissues can be performed for medical reasons, such procedures are usually considered part of pathology instead of medical imaging."
"Measurement and recording techniques, such as electroencephalography (EEG), magnetoencephalography (MEG), electrocardiography (ECG), and others."
"In the case of projectional radiography, the tube uses X-ray radiation."
"X-ray radiation is absorbed at different rates by different tissue types such as bone, muscle, and fat."
