Abstract

An ultrasound system and method provide a workflow to acquire 3D images of the fetal heart gated by a synthetic heart gating signal. An ROI is defined in an ultrasound image which delineates the fetal heart. The ultrasound system is controlled to automatically estimate the fetal heart rate from echo signals received from the ROI. When the system has acquired a stable synthetic heart rate signal, an indication thereof is given to the user and the user then commands the system to acquire 3D fetal heart images for a number of fetal heart cycles which are gated using the synthetic heart rate signal.

First claim

What is claimed is:

1. An ultrasonic diagnostic imaging system for gated acquisition of 3D fetal heart images, the system comprising:
an ultrasound probe including a two dimensional array transducer adapted for 3D fetal imaging;
an image processor adapted to process image signals from the probe for display;
an image display coupled to the image processor;
a graphics generator responsive to a user control adapted to identify a region of interest (ROI) in an ultrasound image,…
