The Philips iE33 cardiovascular ultrasound machine, launched in 2004, has been a cardiovascular gold standard for over a decade. The 2010 iE33 xMatrix model is equipped with xMatrix transducers featuring thousands of elements each, enabling real-time 2-plane imaging and 4D capabilities without a mechanical probe. It also supports QLAB quantification and various cardiovascular-specific software enhancements to boost diagnostic confidence. The Epiq 7 is its replacement, but for similar features focused on radiology or OB/GYN, the Philips iU22 is a preferred choice. Prices start at $8,100.
