Abstract: An ultrasound imaging system may acquire ultrasound data from a heart. The ultrasound data may be analyzed to on-invasively provide a value for cardiac pressure, such as left ventricular end diastolic pressure (LVEDP). In some examples, the ultrasound data may be acquired from B-mode images, Doppler images, and/or strain measurements. In some examples, the ultrasound data may be acquired across an entire cardiac cycle of the heart. In some examples, the ultrasound data may include strain measurements and/or volume measurements of the left atrium. In some examples, the ultrasound data may be analyzed by a correlation algorithm, such as a partial least squares model and/or a neural network.

Abstract: An ultrasonic diagnostic imaging system and method enable the automatic acquisition of standard view planes of the heart in real time, such as the AP4, AP3, and AP2 views. A 3D image of the heart is acquired and the processed in conjunction with a geometrical heart model. The heart model is fitted to the heart in its acquired pose to segment the desired image planes from the 3D image data. During successive image acquisition intervals the image planes are tracked through successive image data as a multi-plane system to update a display of the multiple images. The successive image acquisitions can be volume image acquisitions or multi-plane acquisitions of just the tracked image planes during each acquisition interval.
