"Medical imaging is the technique and process of imaging the interior of a body for clinical analysis and medical intervention."
The use of various imaging techniques such as X-rays, CT scans, MRI, and ultrasound to diagnose and monitor medical conditions.
Anatomy and physiology: The study of the structure and function of the body and its organs.
Medical terminology: The language that healthcare professionals use to describe the human body and its functions.
Radiation safety: The proper handling and protection against ionizing radiation used for diagnostic imaging.
Imaging modalities: X-ray, computed tomography (CT), magnetic resonance imaging (MRI), ultrasound, nuclear medicine, and optical imaging.
Image processing: The techniques to enhance or alter medical images to optimize diagnosis.
Quality assurance: Ensuring the quality and safety of imaging equipment and procedures.
Contrast agents: Substances used in medical imaging to enhance image contrast and help identify specific body structures or functions.
Dosimetry: The measurement of radiation dose received by patients during diagnostic imaging procedures.
Artifacts: The visual distortions or errors that may occur in medical images due to technical or physical factors.
Reconstruction algorithms: The mathematical algorithms used to reconstruct images from raw data acquired during imaging procedures.
Image interpretation: Understanding the anatomy and pathology presented in diagnostic images to make accurate diagnoses.
Radiopharmaceuticals: The use of radioactive materials to diagnose and treat diseases in nuclear medicine.
Instrumentation and equipment: The technology and machinery used for diagnostic imaging procedures.
Image archiving and transmission: The management of medical images and their transfer between healthcare providers.
Regulatory laws and standards: The regulations and standards that govern medical imaging procedures and equipment.
X-ray: X-rays use high-frequency electromagnetic radiation to create images of the body's internal structures.
CT scan: A computed tomography (CT) scan uses X-rays to create cross-sectional images of the body. It is used to diagnose a variety of conditions, including fractures, tumors, and infections.
MRI: Magnetic resonance imaging (MRI) uses a powerful magnetic field, radio waves, and a computer to produce detailed images of the body's internal structures.
Ultrasound: Ultrasound uses high-frequency sound waves to create images of the body's internal structures. It is commonly used for examining pregnant women and diagnosing conditions such as gallstones and kidney stones.
PET scan: A positron emission tomography (PET) scan uses a radioactive substance to produce images of the body's internal structures. It is commonly used to diagnose cancer and neurological diseases.
SPECT scan: A single-photon emission computed tomography (SPECT) scan is a type of nuclear imaging test that uses radioactive material to produce images of the body's internal structures.
Mammography: Mammography is a type of X-ray used to screen for breast cancer in women.
Fluoroscopy: Fluoroscopy is a type of X-ray imaging that allows the physician to view the body in real time.
Angiography: Angiography is an imaging technique used to visualize the blood vessels and blood flow within them.
Endoscopy: Endoscopy is a medical procedure that involves inserting an instrument with a camera into the body to view the internal structures.
Bone densitometry: Bone densitometry is a type of imaging used to measure bone density and diagnose osteoporosis.
"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."
