Cmut-on-cmos based guidewire intravascular imaging

A system for intravascular imaging comprising:

• a guidewire with a first diameter and comprising:
• a proximal end;
• a distal end;
• and
• a core wire;
• a first electronics compartment, with a second diameter, disposed proximate the distal end of the guidewire and comprising a window;
• one or more CMUT imaging arrays disposed on a first silicon chip;
• one or more CMOS electronic devices disposed on the first silicon chip and electrically connected to the one or more CMUT imaging arrays;
• wherein the first silicon chip is disposed in the electronics compartment.
