The cardiac ultrasound chart included a comparison chart of ultrasound system from various vendors. It includes systems used for echocardiography, share use and point-of-care ultrasound (POCUS). Systems range from high-end, flagship systems (listed first in each vendor entry) to mid-range and compact and economical solutions. Basic systems will offer 2-D echo, while top of the line echo systems offer 3-D and 4-D imaging, advanced visualization filters and automated quantification and measurements. POCUS systems are designed for a quick look inside a patient for triage and basic cardiac assessments. Some systems designed for use in cardiac cath labs or hybrid ORs offer transesophageal echo (TEE).
