MEDICAL DICTIONARY TERMS
photocoagulatorAn optical medical instrument that uses an intense, precisely focused beam of light to stop weakened blood vessels from hemorrhaging. The thermal effect of the beam strengthens the weakened vessels and halts any uncontrolled growth. The instrument...
digital radiography (DR)Medical diagnostic (x-ray) imaging using laser printers to produce high-resolution digital hard copy instead of film exposed...
capnometerAn instrument incorporating an infrared detector assembly, used to analyze carbon dioxide gases and in medical applications...
endoscopeA medical instrument used to view inside the human body by inserting the instrument into a natural or created aperture. The...
optical coherence tomography (OCT)A noninvasive (typically medical) optical imaging acquisition technique that uses light waves to form distinct, three...
short-arc lampA compact high-pressure light source in which an electrical discharge between electrodes spaced no more than 12 mm apart...
tissue opticsThe study of the optical properties of living tissue. Increased understanding of the behavior of light in this varied,...
femtosecond laserA type of ultrafast laser that creates a minimal amount of heat-affected zones by having a pulse duration below the...
photodynamic therapy (PDT)A medical technology that uses lasers or other light sources in combination with photosensitizing drugs to treat cancerous...
single-photon emission computed tomography (SPECT)A medical imaging method in which gamma camera heads rotate about the patient to detect radionuclides, enabling physicians...
fluorometryThe analysis and measurement of the fluorescence emitted by a source. Fluorometric processes are more sensitive than light...
nuclear magnetic resonance (NMR)A phenomenon, exploited for medical imaging, in which the nuclei of material placed in a strong magnetic field will absorb...
transversely excited atmosphere carbon dioxide laserAbbreviated TEA CO2 laser. A gas laser that provides shorter pulses and higher peak powers than conventional CO2 lasers. The...
Digital Imaging and Communications in MedicineDigital Imaging and Communications in Medicine (DICOM) is an international standard for medical imaging created by both the...
Secondary Speckle PatternA self-interference effect that generates random patterns; secondary speckle pattern (SSP) typically occurs in diffuse...
ophthalmic photographyThe methods and techniques used to obtain medical photographs of the human eye. To photograph the exterior of the eye,...
multimodality imagingA technique that combines two or more imaging processes in order to minimize the disadvantages within each of the...
borescopeA device for the internal inspection of hard-to-get-at mechanical parts, such as rifle barrels, sewer pipes, oil wells, or...
positron emission tomography (PET)A medical imaging device that uses a ring of crystal/photomultiplier tube assemblies encircling the patient to detect gamma...
