invasive method for imaging the heart. A new generation of three-dimensional (3-D)
ultrasound (US) technology has been developed with real-time 3-D (RT3-D) matrix phased-
array transducers. These transducers allow interactive 3-D visualization of cardiac anatomy
and fast ventricular volume estimation without tomographic interpolation as required with
earlier 3-D US acquisition systems. However, real-time acquisition speed is performed at the …
