摘要： In accordance with the invention, an ultrasound imaging device includes a fluid flow path between a distal end having ultrasound transducers and a proximal end that is electrically coupled to the distal end to enable the exchange of electrical signals. Cooling fluid within the flow path transfers heat generated by the ultrasound transducers and other heat-generating components located at the distal end. The heat flow path is one element of an active thermal management sub-system, which may also include a Thermo Electric Cooler (TEC). The active thermal management sub-system may alternatively or additionally include a heat sink to transfer thermal energy. A temperature monitor may be used for the embodiment in which the sub-system dynamically provides thermal regulation.

摘要： A laser driver circuit to provide a current signal to power a laser device is described. A bias current provided to the laser device may be changed while changes in the output power of a light signal from the laser device is monitored. A slope efficiency associated with the laser device may be determined based upon the changes in the bias current and changes in the output power.
