LiU PhD-student Martin Hultman, Department of Biomedical Engineering (IMT), was given the award for best research presentation at the thirteenth edition of Medicinteknikdagarna, this year held in Västerås. Martin's presentation Multi-exposure Laser Speckle Contrast Imaging for microvascular flow assessment focused on how laser light can be utilized to image the blood flow in the smallest blood vessels in the body; the capillaries. By using a physical phenomenon known as laser speckle and capturing this with a high-speed camera, and by analyzing the images in programmable logic hardware (FPGA), high resolution blood flow images can be presented in real-time. The technique can be used in clinics when investigating blood flow in the skin, which for example is of interest for burn wound assessment and during intervention of critical limb ischemia (CLI).
The award is given by the International Federation for Medical and Biological Engineering (IFMBE) and Svensk förening för medicinsk teknik och fysik (MTF)
