We have the following five types of biomedical instrumentation/measurement systems:
In biomedical instrumentation we may have the sensing system measuring a physiological parameter directly, such as the average blood flow in an artery or … Read More
When a sample is introduced into a flame, only a small fraction of the atoms are in an excited or high energy state [as per the Boltzmann equation] and most atoms of the element remain in the unexcited or ground … Read More
Instruments that are used in biomedical measurements can be grouped into four categories, based on the following:
The techniques employed in … Read More
Though EEG signal detection provides a key indicator for detection of neurological status and disorders, its biomedical application is limited. This is because of the complicated nature of EEG signal and the complexities regarding the interpretation of the signals.
Some … Read More
Modern diagnostic and monitoring ECG acquisition and analysis systems are equipped with modern-day computer technology. ECG monitoring devices constitute an important part of the patient monitoring systems. Patient monitoring systems are used to continuously or intermittently measure the vital signs … Read More
After absorption of light energy, all compounds release some energy as heat; fluorescent compounds represent a special case in which some energy is also given off as light. Spectrofluorimeters are optical devices that measure the amount of light that is … Read More
The principle of immunoassay sensor operation is based on the observation of ligand-binding reaction products between a target analyte and a highly specific binding reagent. The important component of an immunosensor is the biological recognition element, which normally consists of … Read More
Intra-arterial blood gas sensors usually use a single or double fiber configuration. Typically, the matrix containing the indicator is attached to the end of the optical fiber. Because the solubility of O2 and CO2 gases, as well as … Read More
A mass spectrometer is an instrument that produces a stream of charged particles (ions) from a substance being analyzed, separates the ions into a spectrum according to their mass-to-charge ratios, and ascertains the relative abundance of each type of ion … Read More
