Virtual Instrumentation
Virtual instrumentation is an interdisciplinary field that merges sensing, hardware and software technologies
in order to create flexible and sophisticated instruments for control and monitoring applications.There are several definitions for virtual instrumentation. Some of them maybe:
-"an instrument whose general function and capabilities are determined in software"
-any computer can simulate any other if we simply load it with software simulating the other computer.
-a virtual instrument is composed of some specialized subunits, some general-purpose computers, some software, and a little know-how.
Virtual Instrument Architecture
the following blocks are present in a virtual instrument:
-Sensor Module: It performs signal conditioning and transforms it into a digital form for further manipulation
-Sensor Interface:wired and wireless sensor interfaces exist and they are used for communication between sensors modules and the computer
-Medical Information Systems Interface
-Processing Module:Integration of the general purpose microprocessors or microcontrollers allowed flexible implementation of complex processing functions.
-Database Interface: Computerized instrumentation allows measured data to be stored for off-line processing, or to keep records
as a part of the patient record
-User Interface:
For communicating with the user.Graphical User Interfaces (GUI), Multimodal presentation, Virtual and augmented reality, Functional Integration all come under this.
Distributed Virtual Instrumentation
medical information and services can be provided at a distance by physical distribution of virtual instrument components into telemedical systems. The Infrastructure for distributed virtual instrumentation includes:
-Internet
-Mobile telephony
-Medical information system network
-Private networks
