Abstract

Among medical imaging modalities, such as computed tomography (CT) andmagnetic resonance imaging (MRI), ultrasound imaging stands out due to itstemporal resolution. Owing to the nature of medical ultrasound imaging, it has beenused for not only observation of the morphology of living organs but also functionalimaging, such as blood flow imaging and evaluation of the cardiac function. Ultrafastultrasound imaging, which has recently become widely available, significantlyincreases the opportunities for medical functional imaging. Ultrafast ultrasoundimaging typically enables imaging frame-rates of up to ten thousand frames persecond (fps). Due to the extremely high temporal resolution, this enablesvisualization of rapid dynamic responses of biological tissues, which cannot beobserved and analyzed by conventional ultrasound imaging. This Special Issueincludes various studies of improvements to the performance of ultrafast ultrasound

Abstract

This Special Issue “Atmospheric Conditions for Wind Energy Applications” hosts papers on aspects of remote sensing for atmospheric conditions for wind energy applications. Wind lidar technology is presented from a theoretical view on the coherent focused Doppler lidar principles. Furthermore, wind lidar for applied use for wind turbine control, wind farm wake, and gust characterizations is presented, as well as methods to reduce uncertainty when using lidar in complex terrain. Wind lidar observations are used to validate numerical model results. Wind Doppler lidar mounted on aircraft used for observing winds in hurricane conditions and Doppler radar on the ground used for very short-term wind forecasting are presented. For the offshore environment, floating lidar data processing is presented as well as an experiment with wind-profiling lidar on a ferry for model validation. Assessments of wind resources in the coastal zone using wind-profiling lidar and global wind maps using satellite data are presented..
