The Introduction to Biomedical Instrumentation Systems. Some of the areas covered include: The sources of biomedical signals, Performance requirements of biomedical instrumentation systems, factors to consider when designing biomedical instruments, etc.
The use of optical fiber sensors in medical field is based on their ability to transmit light over great distances with low power loss and the interaction of the light with a measurand system.
These sensors are electrically passive … Read More
A transducer is a device that converts one form of energy or variable into another form of energy or variable. A transducer is required to convert physiological variables into electrical signals which are easier to be … Read More
Biomedical signals/physiological signals are those signals (phenomenon that conveys information) which are used primarily for extracting information on a biological system under investigation. Our body produces various physiological signals. The accessibility to these signals is important because these signals:
In most of the medical instrumentation systems, some calibration is necessary at regular intervals during their operation. The calibration signal is applied to the sensor input or as early in the signal processing chain as possible.
In many measurement applications … Read More
Biomedical Instrumentation deals with the measurement and analysis of current or voltage signals from different parts of the body. The human body generates a variety of voltages which are usually very small. Biomedical instrumentation helps medical personnel or physicians … Read More
