| titleOfInvention | Ultrasound device to detect a patient's heartbeat |
| abstract | An apparatus for detecting a heartbeat of a patient includes an ultrasonic transmitter, a Doppler-shifted ultrasonic receiver, and a time-dependent signal (51, 51a) sent by the receiver, the frequency varying with time. And an evaluation means configured to extract the component (51b) and to evaluate the instants t 1 , t 2 , t 3 and t 4 of the heartbeat from the fluctuation of the frequency component within at least one time. In particular, a time-of-interest window (WOI) (53a, 53b, 53c, 53d) is determined from the variation of at least one frequency component. At that time, moment, time-dependent signal from the receiver (51, 51a) is determined as the moment of the maximum value (b 1, b 2, b 3, b 4) in the WOI. The heartbeat can be used to trigger image acquisition, particularly with an MRI device. Tracking means may be provided to determine which transmitter and / or receiver covers the heart, particularly for imaging the fetus. [Selection] Figure 2 |
