"Radiography is an imaging technique using X-rays, gamma rays, or similar ionizing radiation and non-ionizing radiation to view the internal form of an object."
The technical aspects of obtaining radiographic images.
Anatomy and physiology: Understanding the structure and functioning of the human body is crucial to identifying and interpreting radiographic images.
Radiation physics: Fundamental concepts of radiation, types of radiation, radiation units, and radiation interactions with matter.
Radiographic imaging equipment: Understanding the functioning and components of various radiographic imaging equipment like x-ray machines, CT scanners, MRI machines, etc.
Image formation and processing: The process of how digital and analog images are produced and how they are processed to enhance and interpret the detail.
Exposure factors and patient positioning: Selection of appropriate exposure factors and patient positioning for various anatomical regions.
Radiographic positioning: Techniques used to position the body part being imaged to generate high-quality diagnostic images.
Radiographic film processing and quality assurance: The processes used to develop radiographic films and ensuring the quality of images produced.
Radiation protection and safety: How to minimize exposure to radiation and maintain a safe working environment for the patient and the radiographer.
Contrast media: The use of contrast media to enhance visibility of different structures within the body during imaging.
Different imaging modalities: Understanding the use, advantages, and limitations of different radiographic imaging techniques such as x-rays, MRI scans, CT scans, etc.
Radiographic pathology: Understanding how different medical conditions affect the appearance of radiographic images.
Radiographic terminology: Becoming familiar with radiographic terms to effectively communicate with radiologists and other healthcare professionals.
X-Ray: Uses electromagnetic radiation to create a hard tissue image of the human body.
Fluoroscopy: A real-time x-ray used to view the function of organs or blood vessels.
Computed tomography (CT): Uses x-rays to create a 3D image of the body.
Magnetic resonance imaging (MRI): Uses radio waves and a magnetic field to create detailed images of the body’s soft tissues.
Ultrasonography: Uses sound waves to create images of the body’s internal structures.
Angiography: A type of x-ray used to view blood vessels.
Mammography: A low-dose x-ray used to screen for breast cancer in women.
Positron emission tomography (PET): Uses a radioactive tracer to create images of chemical reactions in the body.
Single-photon emission computed tomography (SPECT): Uses a radioactive tracer to create images of how organs and tissues are functioning.
Bone densitometry: Measures bone density to diagnose osteoporosis or monitor response to treatment.
Interventional Radiology: Uses radiology images to guide minimally invasive procedures for treatment or diagnosis.
Digital Radiography: Uses sensors to create digital images, eliminating the need for film.
Conventional Radiography: The traditional method in which an image is created on film.
"Applications of radiography include medical radiography ("diagnostic" and "therapeutic") and industrial radiography."
"A certain amount of the X-rays or other radiation is absorbed by the object, dependent on the object's density and structural composition. The X-rays that pass through the object are captured behind the object by a detector (either photographic film or a digital detector)."
"The generation of flat two-dimensional images by this technique is called projectional radiography."
"In computed tomography (CT scanning) an X-ray source and its associated detectors rotate around the subject which itself moves through the conical X-ray beam produced."
"Information regarding attenuation of these beams is collated and subjected to computation to generate two-dimensional images in three planes (axial, coronal, and sagittal)."
"Radiography is an imaging technique using X-rays, gamma rays, or similar ionizing radiation and non-ionizing radiation."
"Industrial radiography uses similar techniques as medical radiography but is applied in industrial settings, such as inspecting welds in pipelines."
"Similar techniques are used in airport security (where 'body scanners' generally use backscatter X-ray)."
"The X-rays that pass through the object are captured behind the object by a detector (either photographic film or a digital detector)."

"Information regarding attenuation of these beams is collated and subjected to computation to generate two-dimensional images in three planes (axial, coronal, and sagittal) which can be further processed to produce a three-dimensional image."
