Problems solved by technology

[0004] Conventional techniques like STIC have at least two problems: it takes too long to acquire all the data; and the resulting volume has limited resolution in the height direction
For example, a physician holding a 2D array probe and patient simultaneously is more likely to move during longer acquisitions
Any relative movement between the 2D array probe and the patient anatomy being scanned can introduce motion artifacts
Again, any irregularities in the movement of the patient's heart may cause additional motion or spatial artifacts

Abstract

An ultrasound imaging system and method are provided. An ultrasound imaging device (100) includes a probe (106), a display device (118), and a processor (116). The processor is configured to acquire first 4D ultrasound data of the first partial volume (158) for a first period of time that is longer than an estimated cardiac period and to acquire second 4D ultrasound data of the second partial volume (160) for a second period of time that is longer than the estimated cardiac period. The processor is configured to combine the first 4D ultrasound data with the second 4D ultrasound data to generate 4D ultrasound data of a region-of-interest. The processor is configured to display an image generated by the 4D ultrasound data of a region-of-interest.

Description

technical field [0001] The present disclosure generally relates to ultrasound imaging systems and methods for generating 4D ultrasound data of a region of interest by acquiring 4D ultrasound data of multiple local volumes. Background technique [0002] 2D array probes coupled with current generation ultrasound systems are not fast enough to acquire clinically appropriate volume sizes for applications such as fetal heart imaging. Currently, both the required temporal resolution and the required spatial resolution cannot be simultaneously obtained from a single volume acquired with conventional 2D array probes. [0003] Therefore, some conventional ultrasound systems scan slowly across the volume, acquiring 2D image frames at different locations during the scan. For example, for a typical fetal heart rate, the scan may take 8-12 seconds. During scan time, the fetal heart may beat about 16 to 30 times. Phase data indicating the phase of the heart at the time of acquisition o...
