1. A scan head for an ultrasound imaging system, comprising:

  • a scan head body;

    a number of transducer elements disposed within the scan head body;

    a number of electronic components that are electrically coupled to the transducer elements for driving the transducer elements and for processing received echo signals;

    wherein the electronic components are hermetically sealed within a thermally conductive compartment that is spaced from an interior surface of the scan head body to form a plenum between the thermally conductive compartment and the interior surface of the scan head body and wherein the scan head further includesa magnetically controlled fan having motor controlling electronics that are sealed within the thermally conductive compartment and a rotor with a number of fan blades configured to be moved by the motor controlling electronics in order to force air through the plenum and remove heat generated by the electronic components.
