Apparatus, system and method for measuring volumetric flow of blood in a vessel. |
摘要 |
<p>A system (11) for measuring the volumetric flow of blood in a vessel of a patient comprises a transducer (26) positioned in the vessel, which produces a substantially uniform ultrasonic beam which encompasses the vessel. The transducer (26) receives ultrasonic energy scattered from the red blood cells and supplies a signal to a first moment detector (80). A calculated correction factor from a block (82) and the output of the first moment detector (80) provide an electrical output representing volume flow.</p> |
