Concept
Non-invasive techniques refer to methods that do not require incisions into the body or the removal of tissue, making them safer and less painful for patients. These techniques are widely used in medical diagnostics and treatment, as well as in scientific research, due to their minimal risk and recovery time.

Concept
Magnetic Resonance Imaging (MRI) is a non-invasive imaging technique that uses strong magnetic fields and radio waves to generate detailed images of the organs and tissues in the body. It is widely used in medical diagnosis and research due to its ability to provide high-resolution images without exposure to ionizing radiation.
Concept
Ultrasound imaging is a medical technique that uses high-frequency sound waves to produce images of structures within the body, aiding in diagnostics and treatment planning. It is non-invasive, does not use ionizing radiation, and is commonly used in obstetrics, cardiology, and musculoskeletal assessments.
Concept
Computed tomography (CT) is a medical imaging technique that uses computer-processed combinations of multiple X-ray measurements taken from different angles to produce cross-sectional images of specific areas of a scanned object, allowing for detailed internal visualization. It is widely used for diagnostic and therapeutic purposes in various medical fields due to its ability to provide high-resolution images of bones, blood vessels, and soft tissues.
Concept
Electroencephalography (EEG) is a non-invasive technique used to record electrical activity of the brain, typically for diagnosing neurological conditions, studying brain functions, and monitoring brain health. It involves placing electrodes on the scalp to capture brain wave patterns, offering insights into brain states such as sleep, epilepsy, and cognitive processes.
Functional Near-Infrared Spectroscopy (fNIRS) is a non-invasive imaging technique that measures brain activity by detecting changes in blood oxygenation and volume through near-infrared light. It is particularly useful for studying brain function in naturalistic settings and populations where other imaging methods may be impractical, such as infants or mobile subjects.
Concept
Positron Emission Tomography (PET) is a non-invasive imaging technique that allows for the visualization and measurement of metabolic processes in the body by detecting gamma rays emitted from a radioactive tracer injected into the patient. It is widely used in oncology, neurology, and cardiology to assess tissue function and detect diseases such as cancer, Alzheimer's, and heart disease.
Concept
Laser Doppler Flowmetry is a non-invasive technique used to measure blood flow in microvascular systems by analyzing the Doppler shift of laser light scattered by moving red blood cells. It provides valuable insights into tissue perfusion and is widely used in medical research and clinical diagnostics to assess microcirculatory function.
Transcranial Magnetic Stimulation (TMS) is a non-invasive procedure that uses magnetic fields to stimulate nerve cells in the brain, primarily used to treat depression and other neurological disorders. It is considered an alternative treatment when traditional methods like medication and psychotherapy are ineffective, offering a targeted approach with fewer side effects.
Concept
Optical Coherence Tomography (OCT) is a non-invasive imaging technique that uses light waves to capture micrometer-resolution, three-dimensional images from within optical scattering media, such as biological tissues. It is widely used in medical fields like ophthalmology to assess the retina and diagnose conditions like macular degeneration and glaucoma.
Concept
Bioimpedance Analysis is a non-invasive method used to assess body composition by measuring the resistance of body tissues to electrical currents. It is widely used for estimating body fat, muscle mass, and hydration levels, offering a quick and relatively accurate assessment compared to more invasive techniques.
Concept
Biomedical imaging is a critical technology that allows for the non-invasive visualization of the internal structures and functions of the body, aiding in diagnosis, treatment planning, and medical research. It encompasses various techniques that use different physical principles to capture images, each suited for specific applications and providing unique insights into biological processes.
Concept
Field walking is an archaeological survey method where individuals systematically walk over a landscape to collect artifacts from the surface, providing insights into human activity in the area. This non-invasive technique helps archaeologists map out the distribution of artifacts, identify potential excavation sites, and understand historical land use patterns without disturbing the ground.
Non-Invasive Tear Breakup Time (NIBUT) is a diagnostic measure used to assess the stability of the tear film on the eye's surface without physically touching the eye. It provides critical information for diagnosing dry eye conditions and evaluating the effectiveness of treatments by observing the time it takes for dry spots to appear after a complete blink.
Concept
Near-infrared spectroscopy (NIRS) is a non-invasive analytical technique that utilizes the near-infrared region of the electromagnetic spectrum to determine the composition of a sample by measuring the absorption of light. It is widely used in various fields such as medicine, agriculture, and food science for its ability to provide rapid and accurate analysis without the need for extensive sample preparation.
Fiber-optic transillumination is a diagnostic technique that uses a fiber-optic light source to illuminate tissues, allowing for the visualization of structures beneath the surface, such as detecting dental caries or assessing sinus conditions. This non-invasive method enhances diagnostic accuracy by providing a clear view of subsurface anomalies without the need for radiation exposure.
Concept
Demineralization detection involves identifying the early stages of mineral loss in dental tissues, which can lead to tooth decay if not addressed. Advanced techniques such as fluorescence-based imaging and digital radiography are used to detect these changes at a microscopic level before they become clinically visible.
Concept
A tracer is a substance or device used to track the flow or movement of a material, often by emitting a detectable signal or being easily identifiable. Tracers are commonly used in fields such as medicine, environmental science, and engineering to study dynamic processes and diagnose conditions without invasive procedures.
Invasive procedures avoidance emphasizes the importance of minimizing the use of medical interventions that require entering the body, aiming to reduce risks, complications, and recovery time. This approach prioritizes non-invasive or minimally invasive methods, ensuring patient safety and comfort while achieving effective treatment outcomes.
Concept
Ultrasonic scaling is a dental procedure that uses high-frequency sound waves to remove plaque, tartar, and stains from teeth, offering a less invasive and more efficient alternative to traditional manual scaling. It is particularly effective in treating periodontal disease and maintaining oral hygiene, with the added benefit of minimizing discomfort and healing time for the patient.
Concept
UV Transillumination is a diagnostic technique that uses ultraviolet light to illuminate and examine tissues or materials, making it easier to detect abnormalities or structures not visible under normal light. This method is particularly useful in medical diagnostics, forensic science, and material inspection, offering a non-invasive way to observe internal features or defects.
