Abstract
A CMUT on CMOS imaging chip is disclosed. The imaging chip can use direct connection, CMOS architecture to minimize both internal and external connection complexity. Intelligent power management can enable the chip to be used for various imaging applications with strict power constraints, including forward-looking intra-vascular ultrasound imaging. The chip can use digital logic to control transmit and receive events to minimize power consumption and maximize image resolution. The chip can be integrated into a probe, or catheter, and requires minimal external connections. The chip can comprise integrated temperature control to prevent overheating.
