This joint research project combines the capabilities of German, Baltic and Polish industries and SMEs with those of universities in the conception, development and demonstration of the advantages in the use of procedures and algorithms for irregular signal acquisition and subsequent parallel signal processing. In particular, these techniques will be applied to the construction of an innovative, time resolved, medical imaging procedure based on Laser-Doppler flowmetry. This project will investigate the feasibility of an advanced measurement method which might lead to novel and useful instruments e.g. on-line, 2D determination of blood flow in capillaries of the skin.
European links: The project coordinator is leader of the European Concerted Action "Laser-Doppler Flowmetry for Microcirculation Monitoring".
Parallel processing, a powerful technique for fast, cost efficient processing of irregularised data, allows the extension of the applications to new measurement techniques based on emerging alias-free pseudorandomised digital signal processing. These parallel algorithms are currently optimised in cooperation between ISATEC and Latvia. A parallel computer board for on-line, high speed and high resolution processing has been utilised. The sequential application codes have already been transferred to the parallel architecture of the processing board. This includes portable and scaleable migration of existing application codes with high computational costs to parallel environments.
The development of the experimental electromechanical laser scanning device, the implementation and the programming of a control unit have been made by IIE. The testing of the device at different stages of the development takes place in ABF.
New scientific results concerning the clinical and the technical applications of the device under development will be presented at international conferences and published in international journals.
All results of the project will serve at a future manufacturing and exploitation of the prototypes. Profits will be equally shared between the participating institutes and companies but not between the participating individuals.
