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.

Paper on time-reversing a handful of photons in Physical Review Letters

Turbid materials, such as opal glass, white paint, or skin, strongly scatter light, making it impossible to see through them. However, it is well known that light can still be focused through even the most turbid objects, if only you know exactly how that particular object scatters light. In a typical experiment, a megapixel camera is used to record how the light gets scattered. But how much light do you need to accurately record how the light was scattered? Intuitively one would expect one photon per pixel to be the lower limit. Surprisingly, this answer is far from correct. Researchers from the University of Twente and the California Institute of Technology demonstrate that there is no such lower limit, and experimentally demonstrated light focusing with as little as 0.004 harvested scattered photons per camera pixel ... read more

PEPPERED SKIN!

Wiendelt Steenbergen has been granted an STW Open Mind project ‘Peppered skin, and keeping cancer under control’. This is a one year project (grant 50 kEuro) to investigate the primary feasibility of killing circulating tumor cells through the skin. ... read more

Large European Project on breast imaging Granted

A European research consortium will develop a new imaging device for the diagnosis of breast cancer. A prototype of the device will be ready for large scale testing and production in four years. Not only will it provide improved photoacoustic and ultrasound imaging, it will also be able to combine the images generated by both techniques. ... read more

Vidi grant for Ivo Vellekoop

Ivo Vellekoop is awarded prestigious Vidi grant

Microscopes are essential tools in biology, neuroscience, and medicine. Current microscopes excel at imaging processes occurring in single, isolated cells. However, imaging the cells in their natural environment (inside biological tissue) is extremely hard because most biological tissues are non-transparent (turbid). ... read more
