The major functions of the RIS can include patient scheduling, resource management, examination performance tracking, reporting, results distribution, and procedure billing. [2] RIS complements HIS (hospital information systems) and PACS (picture archiving and communication system), and is critical to efficient workflow to radiology practices. [3]
In July 1959 at the 9th International Congress of Radiology, [7] an organization was formed as International Secretariat of Radiographers and Radiological Technicians in Munich, Germany. Its name was then changed to International Society of Radiographers and Radiological Technicians in August 1962.
The systems are also designed to maintain quality with the varying size and attenuation of an individual patient over their length. Implementations vary between manufacturers, some systems are based on a desired noise level in the image, while others are based on a specified reference output (milliampere second, mAs ).
Patient Blood Management is an approach that can be implemented in hospital settings for taking care of people who require blood transfusions. [4] PBM includes techniques that may help ensure each person receiving a blood transfusion receives optimal treatment for their condition and also ensures that the blood supply (bank of donated blood) is maintained to ensure that all people who require ...
Echocardiography uses 2D, 3D, and Doppler imaging to create pictures of the heart and visualize the blood flowing through each of the four heart valves. Echocardiography is widely used in an array of patients ranging from those experiencing symptoms, such as shortness of breath or chest pain, to those undergoing cancer treatments.
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 ("diagnostic" radiography and "therapeutic radiography") and industrial radiography.
Taking an X-ray image with early Crookes tube apparatus, late 1800s.. For the first three decades of medical imaging's existence (1897 to the 1930s), there was no standardized differentiation between the roles that we now differentiate as radiologic technologist (a technician in an allied health profession who obtains the images) versus radiologist (a physician who interprets them).
Perfusion levels also differ from person to person depending on metabolic demand. [citation needed] Examples follow: [citation needed] Heart tissues are considered overperfused because they normally are receiving more blood than the rest of tissues in the organism; they need this blood because they are constantly working.
