An emerging field in three- and four-dimensional (3D/4D) ultrasound involves the use of an electronic matrix transducer with the ability to acquire volumes with speed and enhanced resolution. This new technology holds promise in fetal echocardiography. The recent introduction of matrix array probes in fetal ultrasound has made possible a new modality of volume acquisition and elaboration. This technology has the potential to minimize motion artifacts associated with 3D/4D ultrasound with a satisfactory spatial resolution. The system allows beam steering and focusing in the 3D volume dataset, making it possible to simultaneously examine two different planes of section of the same structure, in real time, without resolution loss. The strength of the Matrix array approach for examination of fetal structures lies in the possibility of directly acquiring a semi toroid volume of ultrasonographic data, creating a new imaging mode called Live 3D Volume Imaging.
