Welcome to the Biomedical Photonic Imaging group

We investigate the use of light for medical purposes. Our final aim is to develop optical and hybrid optical-acoustical technologies for medical diagnosis, in particular in the fields of oncology and wound healing. Physiological properties of primary interest to us are microcirculatory blood flow, hemoglobin concentrations, and blood oxygenation. Our approaches include physical research into light-tissue interaction and its measurement, biomedical engineering to realize suitable instrumentation for in vivo use, and clinical evaluation together with several medical partners.

BMPI welcomes two new members

December 1st 2014: BMPI welcomes two new members. Last month, two new students joined BMPI for their Master assignments.

Gerwin Osnabrugge [Left] is a Biomedical Engineering master student. In coming months, Gerwin will investigate the anisotropic memory effect, which describes the similarity between different interference patterns created by light propagating through a scattering medium. Using this principle, he hope to image fluorescent structures beyond the ballistic regime. For detailed information about this project, contact Dr. Ivo Vellekoop (i.m.vellekoop@utwente.nl). ... read more

BMPI welcomes three new members

June 6th, 2014 - BMPI welcomes three new members: Colin Veenstra , Sjoukje Schoustra and Ivo van der Lugt .Colin and Sjoukje are Master students and Ivo is a Bachelor student. All are studying Biomedical Engineering at University Of Twente.

In coming months, Colin will investigate about the absorption coefficient measurement using integrating sphere. Sjoukje's research will be focussed on second version of Photoacoustic Mammoscope [PAM2] and initial clinical measurements. Ivo's bachelor assignment is aiming at identifying and reducing motion artefacts in LASCA [ Laser Speckle Contrast Analysis] measurements.

BMPI wish them good luck with their assignments!! ... read more
