    Abstract : The main objective for digital image- and video camera systems is to reproduce a real-world scene in such a way that a high visual quality is obtained. A crucial aspect in this regard is, naturally, the quality of the hardware components of the camera device. There are, however, always some undesired limitations imposed by the sensor of the camera.

  5. 5. Optical Monitoring of Cerebral Microcirculation

    Author : Peter Rejmstad; Karin Wårdell; Göran Salerud; Neda Haj-Hosseini; Kerstin Ramser; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical monitoring; cerebral microcirculation; diffuse reflectance spectroswcopy DRS ; laser Doppler flowmetry LDF ;

    Abstract : The cerebral microcirculation consists of a complex network of small blood vessels that support nerve cells with oxygen and nutrition. The blood flow and oxygen delivery in the microcirculatory blood vessels are regulated through mechanisms which may be influenced or impaired by disease or brain damage resulting from conditions such as brain tumors, traumatic brain injury or subarachnoid hemorrhage (SAH).
