Ultrasound probes and their general applications.

Probe	Configuration	Frequency (MHz)	Applications
Standard linear	Long, narrow rectangular probe face	5–13	To visualize superficial structures (such as the pleural space, vascular structures and soft tissue) and for procedural guidance)
Neonatal/pediatric linear	Long, narrow rectangular probe face or hockey stick configuration	7–22	Same as standard linear with a smaller footprint for procedural purposes and for a better fit in between rib spaces
Phased array	Small, square probe face	1–5	For visualization of cardiac anatomy and abdominal compartment
Neonatal/pediatric phased array	Smaller square/rectangular probe face	4–8	Same as standard phased array but with smaller footprint for a better fit in between rib spaces
Curvilinear	Curved/rectangular probe face	1–5	Allows for a deeper penetration with a wide field of view. Used for visualization of the abdominal and thoracic space, as well as for procedural guidance
