Modern 3 tesla clinical MRI scanner. Magnetic resonance imaging (MRI) is a medical imaging technique mostly used in radiology and nuclear medicine in order to investigate the anatomy and physiology of the body, and to detect pathologies including tumors, inflammation, neurological conditions such as stroke, disorders of muscles and joints, and ...
Article 10 of the directive sets out the scope of the derogation for MRI, stating that the exposure limits may be exceeded during "the installation, testing, use, development, maintenance of or research related to magnetic resonance imaging (MRI) equipment for patients in the health sector, provided that certain conditions are met."
Magnetic refrigeration. Gadolinium alloy heats up inside the magnetic field and loses thermal energy to the environment, so it exits the field and becomes cooler than when it entered. Magnetic refrigeration is a cooling technology based on the magnetocaloric effect. This technique can be used to attain extremely low temperatures, as well as the ...
Bathythermograph. The bathythermograph, or BT, also known as the Mechanical Bathythermograph, or MBT; [ 1] is a device that holds a temperature sensor and a transducer to detect changes in water temperature versus depth down to a depth of approximately 285 meters (935 feet). Lowered by a small winch on the ship into the water, the BT records ...
Instruments used specially in radiology are as follows: [ 1][ 2][ 3] high strength (0.15 to 1.5 teslas) [ 4] are used to excite protons that produce the record results (like CT scan). It can show particular tissues more clearly than CT.; [ 4] video link. These radioactive compounds are administered so that specific tissues take them up.
An operating temperature is the allowable temperature range of the local ambient environment at which an electrical or mechanical device operates. The device will operate effectively within a specified temperature range which varies based on the device function and application context, and ranges from the minimum operating temperature to the maximum operating temperature (or peak operating ...
T4-Gutachter. The T4-Gutachter (in English, 'Action T4 experts') were medical experts who were employed by the Zentraldienststelle-T4 to organize and carry out the Action T4 euthanasia program in Nazi Germany. Based on reporting forms with information about the mentally ill and disabled, they decided who would be killed in "euthanasia" centers.
Strain–encoded magnetic resonance imaging ( SENC-MRI) is a magnetic resonance imaging technique for imaging the strain of deforming tissue. It is undergoing testing to diagnose some heart diseases, particularly congenital right ventricle dysfunctions, which are difficult to diagnose. [1] It is an improvement on magnetic resonance elastography ...
