In radar meteorology, the motion of the radar antenna during data collection. Scanning usually follows a systematic pattern involving one of the following: 1) In horizontal scanning, used to generate PPI displays, the antenna is continuously rotated in azimuth around the horizon or is rotated back and forth in a sector (sector scanning); at the completion of each 360?or sector scan, the elevation angle of the scan typically is increased; 2) Vertical scanning, used to generate RHI displays ...

A special test used to diagnose thyroid disease. During this procedure, the amount of iodine "taken up" by the thyroid is measured and images or "pictures" of the thyroid gland are taken. So-called hot spots, or areas of particularly strong energy, represent areas of increased hormone production. Cold spots, or particularly weak energy spots, represent poorly functioning or nonfunctioning areas of the thyroid gland.
