Abstract
A scan head for an ultrasound imaging device has a body that encloses a number of ultrasound transducers and controlling electronics. The electronics are sealed in the body of the scan head. The scan head has a fan that is configured to remove heat caused by the operation of the electronics. The motor is magnetically controlled and has controlling electronics that are sealed in the body of the scan head. In one embodiment, an airflow channel surrounds the electronics in the scan head and the fan is configured to move air through the airflow channel. In another embodiment, the electronics are thermally coupled to a heat exchanger heat via a conductive substrate and the fan is configured to move air over the heat exchanger.
