Introduction

What isVirtual-Bio-Instrumentation

(VBI)?


3/35

The field of Virtual bioinstrumentation was

emerged after year 2000 and finally after 8

years of research work virtual bio-

instrumentation as a fully equipped separate

field from virtual instrumentation and bio-

instrumentation.

History


4/35

VBI Applications

Basic Research

Medical Schools / Universities

Private Research Companies (e.g.Pharmaceuticals)

Typically Animal based (Human data available

in some cases) Freedom to acquire and analyze data

according to individual


5/35

VBI Applications

Clinical Research

Collect data from existing equipment

Often includes statistical analysis based ontreatment protocols

Not many willing to devote time to learn or

program in LabVIEW


6/35

VBI Applications

Medical Informatics

Hospital/Bed Management

ICU Data Monitoring / DisplayHospital / Clinic Diagnostic Tools

Diagnostic Equipment

e.g. Echocardiograph Machine Treatment Equipment

e.g. Ventilator


7/35

Biomedical Fields for DAQ

Common Mechanical Stimuli

Pressures, Flows, Temperatures

Biopotentials

ECG, EMG, ERG, EEG, ENG, etc

micro V/mV levels, > 20 kHz Sample Rate

Imaging Techniques

Echocardiogram, blood vessel contraction

Edge detection, microscopic imaging

Role of Virtual Instrumentation

User-Friendly GUI Interface for Experiments and Analysis

Modular Development Scheme

Flexibility/Adaptability


9/35

VI Development

Simultaneous I/O Data storage for post-processing

Automation and HMI


10/35

Basic Research

Basic Research Field ideal for incorporation of existingNI hardware & LabVIEW.

Requires NI personnel be familiar with biomedicalapplications and sufficiently able to converse in

medical lingo. Requires stronger ties with research equipment

suppliers [e.g. World Precision Instruments (WPI)].

BioBench has been retooled to accommodate a wider

variety of experiments and analysis. NI, suppliers and users should exercise a substantial list

of typical biomedical experiments to understand anddocument issues.

Clinical Research

Clinical Research also has potential for significantinfiltration of VBI

Requires NI personnel be familiar with biomedicalapplications and sufficiently able to converse in medicallingo.

Requires stronger ties with clinical equipment suppliers.

BioBench / LabVIEW incorporate a user-friendly means ofcollecting and automatically synchronizing data frommultiple serial, GPIB, and analog sources.

Serial (RS232) output is most common form availablefrom commercial equipment.

BioBench now has additional flexibility in allowing data tobe analyzed during or after collection

Medical Informatics

The process of transforming data into information inhealthcare.

Electronic Medical Record (EMR)/Computerized PatientRecord (CPR)

Decision support Information retrieval

25/35

Commercial Medical Devices

Hospital / Clinical Diagnostic Tools

Testing and/or development

Requires FDA involvement / approval. Significant time / resource cost for each piece

of equipment developed.

Recommend this development be left to thirdparty vendors for the near future.
