Diffuse correlation spectroscopy is a young but promising optical imaging technique for minimally invasive medical diagnosis. The technique calculates the time resolved correlations of light diffused by a media and it has been proven, for example, that breast tumours appear highly contrasted with this method. However, with biological tissue, the decorrelation time is in the range of a fraction of a millisecond and a high acquisition rate is needed to analyse such a phenomenon. In addition, after being sent through thick tissues, such as a human breast or head, the light signal has low power and a poor signal-to-noise ratio.In their paper in this issue of Electronics Letters, Jean-Michel Tualle, Antoine Dupret and Marius Vasiliu present a breakthrough which the authors believe could lead to many new biomedical applications. The team working in Paris have designed an integrated circuit that combines image acquisition and image processing at a very high rate, which can exceed 10 000 frames per second (fps).
