    Abstract: An ultrasonic diagnostic imaging system is gated to acquire images at different phases of a physiological cycle such as the heartbeat. At each successive heart cycle a trigger actuates the acquisition of a continuous sequence of images, starting at a particular phase of the heart cycle and ending when the next heart cycle begins. Multiple triggers are used, each starting at a different phase of the heart cycle and each acquiring images at uniform temporal spacing. After the first trigger is used a sequence of images has been captured which are temporally evenly spaced over the heart cycle, and as successive triggers are used uniform temporal spacing is maintained as the heart cycle is filled in with additional images for replay of an image loop of phase re-ordered images at a high frame rate of display.

    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.
