PRESSURE-VOLUME WITH MEDICAL DIAGNOSTIC ULTRASOUND IMAGING

摘要

PURPOSE: A pressure volume using medical diagnosis ultrasonic wave imaging is provided to effectively execute an invasive measurement process by using atmospheric pressure. CONSTITUTION: B-mode data and flow ultrasonic wave data are simultaneously obtained (30). A three-dimensional area of a patient is marked in the B-mode data. An obtaining process is repeated in a cardiac cycle (32). The pressure of cardiac thin films is estimated from the flow ultrasonic wave data (40). The volume of the three-dimensional area is calculated from the B-mode data (42).
