  • SMT, 1994-1998. Fifth call for proposals supporting document. Topic 26: Measuring methods and calibration procedure for laser doppler flow meters for the determination of blood perfusion in tissue (LDBP monitoring and imaging)


More detailed and more technical background information is given relating to this topic of the fifth call for proposals under the specific programme for standards, measurements and testing (SMT), 1994-1998. The proposed item has the following general aim:

- Elaboration and description of a complete testing facility for calibration of LDBP meters;
- Definition of a reproducible method to quantify the volume of tissue (particularly the depth) probed by the different instruments available on the market;
- Definition of a quantification method for the blood flow, perfusion, concentration and average velocity in standardized (preferable absolute) units as measured with the different commercialized instruments;
- Method to deduct from the quantification a standard calibration procedure to be used by the clinical users. This would also include a method for interpretation and comparison of obtained measuring results on patients;
- To draft a full report containing proposals to be incorporated in the forthcoming European standard on this matter especially for what concerns building up of equipment for testing, testing and calibration procedures and handling of obtained data.

A time scale and expected result format are also described.
