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. Applications of radiography include medical and industrial radiography. Similar techniques are used in airport security,. To create an image in conventional radiography, a beam of X-rays is produced by an X-ray generator and it is projected towards the object. A certain amount of the X-rays or other radiation are 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. The generation of flat two-dimensional images by this technique is called projectional radiography. In computed tomography, an X-ray source and its associated detectors rotate around the subject, which itself moves through the conical X-ray beam produced. Any given point within the subject is crossed from many directions by many different beams at different times. Information regarding the attenuation of these beams is collated and subjected to computation to generate two-dimensional images on three planes which can be further processed to produce a three-dimensional image.
Radiology is the medical specialty that uses medical imaging to diagnose diseases and guide their treatment, within the bodies of humans and other animals. It began with radiography, but today it includes all imaging modalities, including those that use no ionizing electromagnetic radiation, as well as others that do, such as computed tomography (CT), fluoroscopy, and nuclear medicine including positron emission tomography (PET). Interventional radiology is the performance of usually minimally invasive medical procedures with the guidance of imaging technologies such as those mentioned above.
Interventional radiology (IR) is a medical specialty that performs various minimally-invasive procedures using medical imaging guidance, such as x-ray fluoroscopy, computed tomography, magnetic resonance imaging, or ultrasound. IR performs both diagnostic and therapeutic procedures through very small incisions or body orifices. Diagnostic IR procedures are those intended to help make a diagnosis or guide further medical treatment, and include image-guided biopsy of a tumor or injection of an imaging contrast agent into a hollow structure, such as a blood vessel or a duct. By contrast, therapeutic IR procedures provide direct treatment—they include catheter-based medicine delivery, medical device placement, and angioplasty of narrowed structures.
The Radiological Society of North America (RSNA) is a non-profit organization and an international society of radiologists, medical physicists and other medical imaging professionals representing 31 radiologic subspecialties from 145 countries around the world. Based in Oak Brook, Illinois, it was established in 1915.
Radiographers, also known as radiologic technologists, diagnostic radiographers and medical radiation technologists are healthcare professionals who specialise in the imaging of human anatomy for the diagnosis and treatment of pathology. Radiographers are infrequently, and almost always erroneously, known as x-ray technicians. In countries that use the title radiologic technologist they are often informally referred to as techs in the clinical environment; this phrase has emerged in popular culture such as television programmes. The term radiographer can also refer to a therapeutic radiographer, also known as a radiation therapist.
The Society of Radiographers (SoR) is a professional body and trade union that represents more than 90 percent of the diagnostic and therapeutic radiographers in the United Kingdom. The College of Radiographers (CoR) is a charitable subsidiary of the Society, they are collectively known as the Society and College of Radiographers (SCoR).
The Royal College of Radiologists (RCR) is the professional body responsible for the specialties of clinical oncology and clinical radiology throughout the United Kingdom. Its role is to advance the science and practice of radiology and oncology, further public education, and set appropriate professional standards of practice. The college sets and monitors the educational curriculum for those training to enter the profession, and administers the Fellowship of the Royal College of Radiologists exams. It is a registered charity in the United Kingdom (no. 211540).
Willi A. Kalender is a German medical physicist and professor and former chairman of the Institute of Medical Physics of the University of Erlangen-Nuremberg. Kalender has produced several new technologies in the field of diagnostic radiology imaging.
The American Society of Radiologic Technologists (ASRT) is a professional membership association that serves medical imaging technologists, radiation therapists, and radiologic science students. The organization, located in Albuquerque, New Mexico provides its members with ongoing education and professional development opportunities.
The European Society of Radiology (ESR) is an international medical society based in Vienna, Austria dedicated to the promotion and coordination of scientific, philanthropic, intellectual and professional activities of radiology in Europe. In addition to various other activities, the ESR serves as an umbrella organisation for European radiologists, organises the annual European Congress of Radiology (ECR) and coordinates the publication of European Radiology, a monthly peer-reviewed medical journal. Additionally, the ESR pilots the harmonisation of teaching programmes throughout Europe with various activities and initiatives.
Medical Radiation Scientists (MRS) are healthcare professionals who perform complex diagnostic imaging studies on patients or plan and administer radiation treatments to cancer patients. Medical radiation scientists include diagnostic radiographers, nuclear medicine radiographers, magnetic resonance radiographers, medical/cardiac sonographers, and radiation therapists. Most medical radiation scientists work in imaging clinics and hospitals' imaging departments with the exception of Radiation Therapists, who work in specialised cancer centers and clinics.

He was formerly the Associate Chancellor and Chairman of Radiology at University of California, San Francisco. Over 8 of his papers have each been cited over 100 times.
Madan M. Rehani is an Indian-born medical physicist.
Diagnostically acceptable irreversible compression (DAIC) is the amount of lossy compression which can be used on a medical image to produce a result that does not prevent the reader from using the image to make a medical diagnosis.
Carl Helmut Diefenthal was a German-born American medical missionary, professor, and radiologist who spent more than 25 years working in the Tanzanian town of Moshi. He and his wife founded the Kilimanjaro School of Radiology in the late 1980s.
World Radiography Day marks the anniversary of the discovery of X-rays in 1895. The purpose of this day is to raise public awareness of radiographic imaging and therapy, which play a crucial role in the diagnosis and the treatment of patients and, most importantly, ensuring radiation is kept to the minimum required, hence improving the quality of patient care. The day is celebrated worldwide by various national radiographers' associations and societies, including Nigeria's Association of Radiographers of Nigeria, United Kingdom's Society of Radiographers (SoR), among others. The International Society of Radiographers and Radiological Technologists have celebrated 8 November as World Radiography Day since 2007. 2007. 'Radiographers Association of Madhya Pradesh(India)''' has celebrated this day since 1996 and the theme for this day was raised by '''Mr.Shivakant Vajpai''', Secretary of Madhya Pradesh Radiographers Association, also holding a designation of Radiation Safety Officer and Senior Radiographer in government of Madhya Pradesh, India.
