To keep the temperature of an ultrasound probe down, the probe is operated at a low frame rate (with correspondingly low heat generation) for the vast majority of time. Probe operation is only switched to the high frame rate temporarily at times when high temporal resolution is needed, preferably under...http://www.google.es/patents/US8165364?utm_source=gb-gplus-sharePatente US8165364 - Temperature management for ultrasound imaging at high frame rates
