Also known as an infant warmer, a radiant warmer is a medical apparatus which consists of an open bed with an overhead warmer which is used to keep an infant warm.
radiation oncology
Radiation oncology is the branch of radiology that uses radiant energy and isotopes in the study and treatment of diseases, especially malignant cancer.
radiology
Concerned with the use of radiation (such as x-rays) or other imaging technologies (such as ultrasound and magnetic resonance imaging) to diagnose or treat disease.
radiolucent
Radiodensity is the property of relative transparency to the passage of X-rays through a material. Radiolucent indicates greater transparency to X-ray photons. For example, a radiolucent table permits the passage of x-rays without leaving a shadow on the film. Soft tissues are radiolucent; bones are not.
radiometry
The measurement of radiation by photography, as in x-ray film and film badge, by Geiger-Mueller tube, and by scintillation counting.
Randall forceps
Breathing circuits used during the administration of anesthesia in which the exhaled gas is recirculated to the patient with CO2 removed.
reconstructive surgery
Concerned with the problems related to endocrinology and infertility.
respiration rate
The number of breaths (inspirations and expirations) in one minute.
retinoscope
Instruments for retinoscopy that determines the refractive state of the eye. In principle, a retinoscope provides a light source to illuminate the retina, and then locates the aerial image of the retina in space to obtain an index of the refractive quality of the patient's lens system.
retractor
A surgical instrument used to hold back organs or the edges of an incision.
reverse trendelenburg
A position in which the lower extremities are lower than the body and head, which are elevated on an inclined plane.
rheology
The study of the deformation and flow of matter, usually liquids or fluids, and of the plastic flow of solids. The concept covers consistency, dilatancy, liquefaction, resistance to flow, shearing, and viscosity
rheumatology
Concerned with the diseases of the joints, muscles, bones, and tendons, including arthritis, back pain, and muscle strains.
rhinolaryngoscope
A rigid medical device used in the examination of the upper respiratory tract. The instrument includes a lamp at the tip for illumination and a built-in optical system.
