Test Statistics-BioInstrumentation

In this article, we will learn about different test parameters that are required after performing medical tests on patients to analyse statistical data. We may define terms for test results 1. True positive (TP):  A true positive test result is one that detects the condition when the condition is present. TP denotes the number of true … Read moreTest Statistics-BioInstrumentation

LASER Working | Types & Applications

LASER LASER stands for Light Amplification by Stimulated Emission of Radiation. LASER is a narrow beam of light of a single wavelength (monochromatic) in which each wave is in phase(coherent) with other near it. Laser apparatus Laser apparatus is a device that produces an intense concentrated, and a highly parallel beam of coherent light. Atom … Read moreLASER Working | Types & Applications

Ultrasound Principle | Working & Applications

What is Ultrasound? Ultrasound or ultrasonography is a medical imaging technique that uses high-frequency sound waves and their echoes to create images of the inside of the body. This technique is similar to the SONAR used by submarines, echolocation used by bats, dolphins, and whales. How Ultrasound Creates an Image A gel is applied to the body area which … Read moreUltrasound Principle | Working & Applications

Human Body Anatomical Planes & Sections

Body Planes They are the hypothetical geometric planes that are used to divide the body into sections. Body Planes are commonly used in both human and zoological anatomy to describe the location or direction of bodily structures. 1. Sagittal or median plane divides the body into sinister and dexter (left and right) sides. 2. Coronal … Read moreHuman Body Anatomical Planes & Sections

Electroencephalography or EEG

Electroencephalography or EEG is the technique of capturing brain’s electrical activity. It was first discovered by Hans Berger in 1929. EEG signal recording can be done using scalp electrodes or intracranial procedure of capturing EEG. International 10-20 system of electrode placement is widely used across the globe for recording scalp EEG. Neurologist classified the brain … Read moreElectroencephalography or EEG
