Query: An Updated Review of Methods and Advancements in Microvascular Blood
  Flow Imaging   There has been a consistent growth in research involving imaging of
microvasculature over the past few decades. By 2008, publications mentioning
the microcirculation had grown more than 2000 per annum. Many techniques have
been demonstrated for measurement of the microcirculation ranging from the
earliest invasive techniques to the present high speed, high resolution
non-invasive imaging techniques. Understanding the microvasculature is vital in
tackling fundamental research questions as well as to understand effects of
disease progression on the physiological wellbeing of an individual. We have
previously provided a wide ranging review [38] covering most of the available
techniques and their applications. In this review, we discuss the recent
advances made and applications in the field of microcirculation imaging.
